Living organisms including humans are social when they live collectively in interacting populations, whether they are aware of it, and whether the interaction is voluntary or involuntary.

Gainsborough 18de eeuw
Conversation in a Park by Thomas Gainsborough, 1745


The word "Social" derives from the Latin word socii ("allies"). It is particularly derived from the Italian Socii states, historical allies of the Roman Republic (although they rebelled against Rome in the Social War of 91-88 BC).


In the absence of agreement about its meaning, the term "social" is used in many different senses and regarded as a concept, referring among other things to:

Attitudes, orientations, or behaviors which take the interests, intentions, or needs of other people into account (in contrast to anti-social behaviour) has played some role in defining the idea or the principle. For instance terms like social realism, social justice, social constructivism, social psychology, social anarchism and social capital imply that there is some social process involved or considered, a process that is not there in regular, "non-social" realism, justice, constructivism, psychology, anarchism, or capital.

The adjective "social" is also used often in politics, although its meaning in a context depends heavily on who is using it. In left-wing circles it is often used to imply a liberal characteristic, while in right-wing circles it is generally used to imply a conservative characteristic. This adjective is used much more often by those on the political left than by those on the political right. For these reasons, those seeking to avoid association with the left-right political debates often seek to label their work with phrases that do not include the word "social". An example is quasi-empiricism in mathematics which is sometimes labelled social constructivism by those who see it as an unwarranted intrusion of social considerations in mathematical practice.

Social theorists

In the view of Karl Marx[1], human beings are intrinsically, necessarily and by definition social beings who, beyond being "gregarious creatures", cannot survive and meet their needs other than through social co-operation and association. Their social characteristics are therefore to a large extent an objectively given fact, stamped on them from birth and affirmed by socialization processes; and, according to Marx, in producing and reproducing their material life, people must necessarily enter into relations of production which are "independent of their will".

By contrast, the sociologist Max Weber[1] for example defines human action as "social" if, by virtue of the subjective meanings attached to the action by individuals, it "takes account of the behavior of others, and is thereby oriented in its course".

In socialism

The term "socialism", used from the 1830s onwards in France and the United Kingdom, was directly related to what was called the social question. In essence, early socialists contended that the emergence of competitive market societies did not create "liberty, equality and fraternity" for all citizens, requiring the intervention of politics and social reform to tackle social problems, injustices and grievances (a topic on which Jean-Jacques Rousseau discourses at length in his classic work The Social Contract). Originally the term "socialist" was often used interchangeably with "co-operative", "mutualist", "associationist" and "collectivist" in reference to the organization of economic enterprise socialists advocated, in contrast to the private enterprise and corporate organizational structures inherent to capitalism.

The modern concept of socialism evolved in response to the development of industrial capitalism. The "social" in modern "socialism" came to refer to the specific perspective and understanding socialists had of the development of material, economic forces and determinants of human behavior in society. Specifically, it denoted the perspective that human behavior is largely determined by a person's immediate social environment, that modes of social organization were not supernatural or metaphysical constructs but products of the social system and social environment, which were in turn products of the level of technology/mode of production (the material world), and were therefore constantly changing. Social and economic systems were thus not the product of innate human nature, but of the underlying form of economic organization and level of technology in a given society, implying that human social relations and incentive-structures would also change as social relations and social organization changes in response to improvements in technology and evolving material forces (relations of production). This perspective formed the bulk of the foundation for Karl Marx's materialist conception of history.

Modern uses

In contemporary society, "social" often refers to the redistributive policies of the government which aim to apply resources in the public interest, for example, [social security]. Policy concerns then include the problems of social exclusion and social cohesion. Here, "social" contrasts with "private" and to the distinction between the public and the private (or privatised) spheres, where ownership relations define access to resources and attention.

The social domain is often also contrasted with that of physical nature, but in sociobiology analogies are drawn between humans and other living species in order to explain social behavior in terms of biological factors. The term "social" is also added in various other academic sub-disciplines such as social geography, social psychology, social anthropology, social philosophy, social ontology, social statistics and social choice theory in mathematics.

Asperger syndrome

Asperger syndrome (AS), also known as Asperger's, is a developmental disorder characterised by significant difficulties in social interaction and nonverbal communication, along with restricted and repetitive patterns of behavior and interests. As a milder autism spectrum disorder (ASD), it differs from other ASDs by relatively normal language and intelligence. Although not required for diagnosis, physical clumsiness and unusual use of language are common. Signs usually begin before two years of age and typically last for a person's entire life.The exact cause of Asperger's is unknown. While it is probably partly inherited, the underlying genetics have not been determined conclusively. Environmental factors are also believed to play a role. Brain imaging has not identified a common underlying problem. In 2013, the diagnosis of Asperger's was removed from the Diagnostic and Statistical Manual of Mental Disorders (DSM-5), and people with these symptoms are now included within the autism spectrum disorder along with autism and pervasive developmental disorder not otherwise specified (PDD-NOS). It remains within the International Classification of Diseases (ICD-11) as of 2019 but as a subtype of autism spectrum disorder.There is no single treatment, and the effectiveness of particular interventions is supported by only limited data. Treatment is aimed at improving poor communication skills, obsessive or repetitive routines and physical clumsiness. Interventions may include social skills training, cognitive behavioral therapy, physical therapy, speech therapy, parent training, and medications for associated problems, such as mood or anxiety. Most children improve as they grow up, but social and communication difficulties usually persist. Some researchers and people on the autism spectrum have advocated a shift in attitudes toward the view that autism spectrum disorder is a difference rather than a disease that must be treated or cured.In 2015, Asperger's was estimated to affect 37.2 million people globally. Autism spectrum disorder affects males more often than females. The syndrome is named after the Austrian pediatrician Hans Asperger, who, in 1944, described children in his practice who lacked nonverbal communication, had limited understanding of others' feelings, and were physically clumsy. The modern conception of Asperger syndrome came into existence in 1981 and went through a period of popularization. It became a standardized diagnosis in the early 1990s. Many questions and controversies remain. There is doubt about whether it is distinct from high-functioning autism (HFA). Partly because of this, the percentage of people affected is not firmly established.

B. R. Ambedkar

Bhimrao Ramji Ambedkar (14 April 1891 – 6 December 1956), popularly known as Babasaheb Ambedkar, was an Indian jurist, economist, politician and social reformer who inspired the Dalit Buddhist movement and campaigned against social discrimination towards the untouchables (Dalits), while also supporting the rights of women and labour. He was independent India's first law and justice minister, the architect of the Constitution of India, and a founding father of the Republic of India. In India and elsewhere, he was often called Babasaheb, meaning "respected father" in Marathi and Hindi.

Ambedkar was a prolific student earning doctorates in economics from both Columbia University and the London School of Economics and gained a reputation as a scholar for his research in law, economics, and political science. In his early career, he was an economist, professor, and lawyer. His later life was marked by his political activities; he became involved in campaigning and negotiations for India's independence, publishing journals, advocating political rights and social freedom for Dalits, and contributing significantly to the establishment of the state of India. In 1956, he converted to Buddhism initiating mass conversions of Dalits.

In 1990, the Bharat Ratna, India's highest civilian award, was posthumously conferred upon Ambedkar. Ambedkar's legacy includes numerous memorials and depictions in popular culture.


Communication (from Latin communicare, meaning "to share") is the act of conveying meanings from one entity or group to another through the use of mutually understood signs, symbols, and semiotic rules.

The main steps inherent to all communication are:

The formation of communicative motivation or reason.

Message composition (further internal or technical elaboration on what exactly to express).

Message encoding (for example, into digital data, written text, speech, pictures, gestures and so on).

Transmission of the encoded message as a sequence of signals using a specific channel or medium.

Noise sources such as natural forces and in some cases human activity (both intentional and accidental) begin influencing the quality of signals propagating from the sender to one or more receivers.

Reception of signals and reassembling of the encoded message from a sequence of received signals.

Decoding of the reassembled encoded message.

Interpretation and making sense of the presumed original message.The scientific study of communication can be divided into:

Information theory which studies the quantification, storage, and communication of information in general;

Communication studies which concerns human communication;

Biosemiotics which examines communication in and between living organisms in general.The channel of communication can be visual, auditory, tactile (such as in Braille) and haptic, olfactory, electromagnetic, or biochemical.

Human communication is unique for its extensive use of abstract language. Development of civilization has been closely linked with progress in telecommunication.


In political and social sciences, communism (from Latin communis, "common, universal") is the philosophical, social, political, and economic ideology and movement whose ultimate goal is the establishment of the communist society, which is a socioeconomic order structured upon the common ownership of the means of production and the absence of social classes, money, and the state.Communism includes a variety of schools of thought, which broadly include Marxism and anarchism (anarcho-communism), as well as the political ideologies grouped around both. All of these share the analysis that the current order of society stems from its economic system, capitalism; that in this system there are two major social classes; that conflict between these two classes is the root of all problems in society; and that this situation will ultimately be resolved through a social revolution.

The two classes are the working class—who must work to survive and who make up the majority within society—and the capitalist class—a minority who derives profit from employing the working class through private ownership of the means of production.

The revolution will put the working class in power and in turn establish social ownership of the means of production, which according to this analysis is the primary element in the transformation of society towards communism.

Critics of communism can be roughly divided into those concerning themselves with the practical aspects of 20th century communist states and those concerning themselves with communist principles and theory.Marxism-Leninism and democratic socialism were the two dominant forms of socialism in the 20th century; democratic socialism advocates economic reform through gradual democratic legislative action rather than through revolution.


Culture () is the social behavior and norms found in human societies. Culture is considered a central concept in anthropology, encompassing the range of phenomena that are transmitted through social learning in human societies. Cultural universals are found in all human societies; these include expressive forms like art, music, dance, ritual, religion, and technologies like tool usage, cooking, shelter, and clothing. The concept of material culture covers the physical expressions of culture, such as technology, architecture and art, whereas the immaterial aspects of culture such as principles of social organization (including practices of political organization and social institutions), mythology, philosophy, literature (both written and oral), and science comprise the intangible cultural heritage of a society.In the humanities, one sense of culture as an attribute of the individual has been the degree to which they have cultivated a particular level of sophistication in the arts, sciences, education, or manners. The level of cultural sophistication has also sometimes been seen to distinguish civilizations from less complex societies. Such hierarchical perspectives on culture are also found in class-based distinctions between a high culture of the social elite and a low culture, popular culture, or folk culture of the lower classes, distinguished by the stratified access to cultural capital. In common parlance, culture is often used to refer specifically to the symbolic markers used by ethnic groups to distinguish themselves visibly from each other such as body modification, clothing or jewelry. Mass culture refers to the mass-produced and mass mediated forms of consumer culture that emerged in the 20th century. Some schools of philosophy, such as Marxism and critical theory, have argued that culture is often used politically as a tool of the elites to manipulate the lower classes and create a false consciousness, and such perspectives are common in the discipline of cultural studies. In the wider social sciences, the theoretical perspective of cultural materialism holds that human symbolic culture arises from the material conditions of human life, as humans create the conditions for physical survival, and that the basis of culture is found in evolved biological dispositions.

When used as a count noun, a "culture" is the set of customs, traditions, and values of a society or community, such as an ethnic group or nation. Culture is the set of knowledge acquired over time. In this sense, multiculturalism values the peaceful coexistence and mutual respect between different cultures inhabiting the same planet. Sometimes "culture" is also used to describe specific practices within a subgroup of a society, a subculture (e.g. "bro culture"), or a counterculture. Within cultural anthropology, the ideology and analytical stance of cultural relativism holds that cultures cannot easily be objectively ranked or evaluated because any evaluation is necessarily situated within the value system of a given culture.


Facebook, Inc. is an American online social media and social networking service company. It is based in Menlo Park, California. It was founded by Mark Zuckerberg, along with fellow Harvard College students and roommates Eduardo Saverin, Andrew McCollum, Dustin Moskovitz and Chris Hughes. It is considered one of the Big Four technology companies along with Amazon, Apple, and Google.The founders initially limited the website's membership to Harvard students and subsequently Columbia, Stanford, and Yale students. Membership was eventually expanded to the remaining Ivy League schools, MIT, and higher education institutions in the Boston area. Facebook gradually added support for students at various other universities, and eventually to high school students. Since 2006, anyone who claims to be at least 13 years old has been allowed to become a registered user of Facebook, though variations exist in this requirement, depending on local laws. The name comes from the face book directories often given to American university students. Facebook held its initial public offering (IPO) in February 2012, valuing the company at $104 billion, the largest valuation to date for a newly listed public company. It began selling stock to the public three months later. Facebook makes most of its revenue from advertisements that appear onscreen.

The Facebook service can be accessed from devices with Internet connectivity, such as personal computers, tablets and smartphones. After registering, users can create a customized profile revealing information about themselves. Users can post text, photos and multimedia of their own devising and share it with other users as "friends". Users can use various embedded apps, and receive notifications of their friends' activities. Users may join common-interest groups.

Facebook had more than 2.3 billion monthly active users as of December 2018. It receives prominent media coverage, including many controversies such as user privacy and psychological effects. The company has faced intense pressure over censorship and over content that some users find objectionable.

Facebook offers other products and services. It acquired Instagram, WhatsApp, Oculus Rift, and GrokStyle and independently developed Facebook Messenger.


Gender is the range of characteristics pertaining to, and differentiating between, masculinity and femininity. Depending on the context, these characteristics may include biological sex (i.e., the state of being male, female, or an intersex variation), sex-based social structures (i.e., gender roles), or gender identity. Traditionally, people who identify as men or women or use masculine or feminine gender pronouns are using a system of gender binary whereas those who exist outside these groups fall under the umbrella terms non-binary or genderqueer. Some cultures have specific gender roles that are distinct from "man" and "woman," such as the hijras of South Asia. These are often referred to as third genders.

Sexologist John Money introduced the terminological distinction between biological sex and gender as a role in 1955. Before his work, it was uncommon to use the word gender to refer to anything but grammatical categories. However, Money's meaning of the word did not become widespread until the 1970s, when feminist theory embraced the concept of a distinction between biological sex and the social construct of gender. Today, the distinction is followed in some contexts, especially the social sciences and documents written by the World Health Organization (WHO).In other contexts, including some areas of the social sciences, gender includes sex or replaces it. For instance, in non-human animal research, gender is commonly used to refer to the biological sex of the animals. This change in the meaning of gender can be traced to the 1980s. In 1993, the US Food and Drug Administration (FDA) started to use gender instead of sex. Later, in 2011, the FDA reversed its position and began using sex as the biological classification and gender as "a person's self representation as male or female, or how that person is responded to by social institutions based on the individual's gender presentation."The social sciences have a branch devoted to gender studies. Other sciences, such as sexology and neuroscience, are also interested in the subject. The social sciences sometimes approach gender as a social construct, and gender studies particularly do, while research in the natural sciences investigates whether biological differences in males and females influence the development of gender in humans; both inform debate about how far biological differences influence the formation of gender identity. In some English literature, there is also a trichotomy between biological sex, psychological gender, and social gender role. This framework first appeared in a feminist paper on transsexualism in 1978.

Karl Marx

Karl Marx (German: [ˈkaɐ̯l ˈmaɐ̯ks]; 5 May 1818 – 14 March 1883) was a German philosopher, economist, historian, sociologist, political theorist, journalist and socialist revolutionary.

Born in Trier, Germany, Marx studied law and philosophy at university. He married Jenny von Westphalen in 1843. Due to his political publications, Marx became stateless and lived in exile with his wife and children in London for decades, where he continued to develop his thought in collaboration with German thinker Friedrich Engels and publish his writings, researching in the reading room of the British Museum. His best-known titles are the 1848 pamphlet, The Communist Manifesto, and the three-volume Das Kapital. His political and philosophical thought had enormous influence on subsequent intellectual, economic and political history and his name has been used as an adjective, a noun and a school of social theory.

Marx's theories about society, economics and politics – collectively understood as Marxism – hold that human societies develop through class struggle. In capitalism, this manifests itself in the conflict between the ruling classes (known as the bourgeoisie) that control the means of production and the working classes (known as the proletariat) that enable these means by selling their labour power in return for wages. Employing a critical approach known as historical materialism, Marx predicted that, like previous socio-economic systems, capitalism produced internal tensions which would lead to its self-destruction and replacement by a new system: socialism. For Marx, class antagonisms under capitalism, owing in part to its instability and crisis-prone nature, would eventuate the working class' development of class consciousness, leading to their conquest of political power and eventually the establishment of a classless, communist society constituted by a free association of producers. Marx actively pressed for its implementation, arguing that the working class should carry out organised revolutionary action to topple capitalism and bring about socio-economic emancipation.Marx has been described as one of the most influential figures in human history, and his work has been both lauded and criticised. His work in economics laid the basis for much of the current understanding of labour and its relation to capital, and subsequent economic thought. Many intellectuals, labour unions, artists and political parties worldwide have been influenced by Marx's work, with many modifying or adapting his ideas. Marx is typically cited as one of the principal architects of modern social science.


Law is a system of rules that are created and enforced through social or governmental institutions to regulate behavior. It has been defined both as "the Science of Justice" and "the Art of Justice". Law is a system that regulates and ensures that individuals or a community adhere to the will of the state. State-enforced laws can be made by a collective legislature or by a single legislator, resulting in statutes, by the executive through decrees and regulations, or established by judges through precedent, normally in common law jurisdictions. Private individuals can create legally binding contracts, including arbitration agreements that may elect to accept alternative arbitration to the normal court process. The formation of laws themselves may be influenced by a constitution, written or tacit, and the rights encoded therein. The law shapes politics, economics, history and society in various ways and serves as a mediator of relations between people.

A general distinction can be made between (a) civil law jurisdictions, in which a legislature or other central body codifies and consolidates their laws, and (b) common law systems, where judge-made precedent is accepted as binding law. Historically, religious laws played a significant role even in settling of secular matters, and is still used in some religious communities. Islamic Sharia law is the world's most widely used religious law, and is used as the primary legal system in some countries, such as Iran and Saudi Arabia.The adjudication of the law is generally divided into two main areas. Criminal law deals with conduct that is considered harmful to social order and in which the guilty party may be imprisoned or fined. Civil law (not to be confused with civil law jurisdictions above) deals with the resolution of lawsuits (disputes) between individuals and/or organizations.Law provides a source of scholarly inquiry into legal history, philosophy, economic analysis and sociology. Law also raises important and complex issues concerning equality, fairness, and justice.


Marxism is a theory and method of working class self-emancipation. As a theory, it relies on a method of socioeconomic analysis that views class relations and social conflict using a materialist interpretation of historical development and takes a dialectical view of social transformation. It originates from the works of 19th-century German philosophers Karl Marx and Friedrich Engels.

Marxism uses a methodology, now known as historical materialism, to analyze and critique the development of class society and especially of capitalism as well as the role of class struggles in systemic economic, social, and political change.

According to Marxist theory, in capitalist societies, class conflict arises due to contradictions between the material interests of the oppressed and exploited proletariat—a class of wage labourers employed to produce goods and services—and the bourgeoisie—the ruling class that owns the means of production and extracts its wealth through appropriation of the surplus product produced by the proletariat in the form of profit.

This class struggle that is commonly expressed as the revolt of a society's productive forces against its relations of production, results in a period of short-term crises as the bourgeoisie struggle to manage the intensifying alienation of labor experienced by the proletariat, albeit with varying degrees of class consciousness.

In periods of deep crisis, the resistance of the oppressed can culminate in a proletarian revolution which, if victorious, leads to the establishment of socialism—a socioeconomic system based on social ownership of the means of production, distribution based on one's contribution and production organized directly for use. As the productive forces continued to advance, Marx hypothesized that socialism would ultimately be transformed into a communist society: a classless, stateless, humane society based on common ownership and the underlying principle: "From each according to his ability, to each according to his needs".

Marxism has developed into many different branches and schools of thought, with the result that there is now no single definitive Marxist theory. Different Marxian schools place a greater emphasis on certain aspects of classical Marxism while rejecting or modifying other aspects. Many schools of thought have sought to combine Marxian concepts and non-Marxian concepts, which has then led to contradicting conclusions. However, lately there is movement toward the recognition that historical materialism and dialectical materialism remains the fundamental aspect of all Marxist schools of thought.Marxism has had a profound impact on global academia and has influenced many fields such as archaeology, anthropology, media studies, political science, theater, history, sociology, art history and theory, cultural studies, education, economics, ethics, criminology, geography, literary criticism, aesthetics, film theory, critical psychology and philosophy.


Psychology is the science of behavior and mind (not to be confused with neuroscience, which studies the neural underpinnings of psychological phenomena ex. neural circuits). Psychology includes the study of conscious and unconscious phenomena, as well as feeling and thought. It is an academic discipline of immense scope. Psychologists seek an understanding of the emergent properties of brains, and all the variety of phenomena linked to those emergent properties. As a social science it aims to understand individuals and groups by establishing general principles and researching specific cases.In this field, a professional practitioner or researcher is called a psychologist and can be classified as a social, behavioral, or cognitive scientist. Psychologists attempt to understand the role of mental functions in individual and social behavior, while also exploring the physiological and biological processes that underlie cognitive functions and behaviors.

Psychologists explore behavior and mental processes, including perception, cognition, attention, emotion (affect), intelligence, phenomenology, motivation (conation), brain functioning, and personality. This extends to interaction between people, such as interpersonal relationships, including psychological resilience, family resilience, and other areas. Psychologists of diverse orientations also consider the unconscious mind. Psychologists employ empirical methods to infer causal and correlational relationships between psychosocial variables. In addition, or in opposition, to employing empirical and deductive methods, some—especially clinical and counseling psychologists—at times rely upon symbolic interpretation and other inductive techniques. Psychology has been described as a "hub science" in that medicine tends to draw psychological research via neurology and psychiatry, whereas social sciences most commonly draws directly from sub-disciplines within psychology.While psychological knowledge is often applied to the assessment and treatment of mental health problems, it is also directed towards understanding and solving problems in several spheres of human activity. By many accounts psychology ultimately aims to benefit society. The majority of psychologists are involved in some kind of therapeutic role, practicing in clinical, counseling, or school settings. Many do scientific research on a wide range of topics related to mental processes and behavior, and typically work in university psychology departments or teach in other academic settings (e.g., medical schools, hospitals). Some are employed in industrial and organizational settings, or in other areas such as human development and aging, sports, health, and the media, as well as in forensic investigation and other aspects of law.

Republican Party (United States)

The Republican Party, also referred to as the GOP (Grand Old Party), is one of the two major political parties in the United States; the other is its historic rival, the Democratic Party.

The GOP was founded in 1854 by opponents of the Kansas-Nebraska Act, which had expanded slavery into U.S. territories. The party originally subscribed to classical liberalism and took ideological stands that were anti-slavery and pro-economic reform. Abraham Lincoln was the first Republican president in the history of the United States; under his leadership and the leadership of a Republican Congress, slavery was banned in the United States in 1865. The Party was usually dominant over the Democrats during the Third Party System and Fourth Party System. In 1912, Theodore Roosevelt formed the Progressive ("Bull Moose") Party after being rejected by the GOP and ran unsuccessfully as a third-party presidential candidate calling for social reforms. After the 1912 election, many Roosevelt supporters left the Party, and the Party underwent an ideological shift to the right.The liberal Republican element in the GOP was overwhelmed by a conservative surge begun by Barry Goldwater in 1964 that continued during the Reagan Era in the 1980s. After the Civil Rights Act of 1964 and the Voting Rights Act of 1965, the party's core base shifted, with the Southern states becoming more reliably Republican in presidential politics and the Northeastern states becoming more reliably Democratic. White voters increasingly identified with the Republican Party after the 1960s. Following the Supreme Court's 1973 decision in Roe v. Wade, the Republican Party made opposition to abortion a key plank of its national party platform and grew its support among evangelicals. By 2000, the Republican Party was aligned with Christian conservatism. The Party's core support since the 1990s comes chiefly from the South, the Great Plains, the Mountain States and rural areas in the North.The 21st century Republican Party ideology is American conservatism, which contrasts with the Democrats' liberal platform and progressive wing. The GOP supports lower taxes, free market capitalism, a strong national defense, gun rights, deregulation and restrictions on labor unions. The GOP was strongly committed to protectionism and tariffs from its founding until the 1930s when it was based in the industrial Northeast and Midwest, but has grown more supportive of free trade since 1952. In addition to advocating for conservative economic policies, the Republican Party is socially conservative.

There have been 19 Republican presidents—the most from any one party—with the most recent being the 45th and current president Donald Trump. Following the 2018 midterm elections, the GOP currently holds the bulk of the political power in the United States, controlling the presidency, a majority in the U.S. Senate, a majority of governorships, a majority of state legislatures (30/50 with shared control of two others), and 22 state "trifectas" (controlling the executive branch and both chambers of the legislative branch). As of April 2019, five of the nine current U.S. Supreme Court justices have been nominated by Republican presidents.

Social class

A social class is a set of subjectively defined concepts in the social sciences and political theory centered on models of social stratification in which people are grouped into a set of hierarchical social categories, the most common being the upper, middle and lower classes.

"Class" is a subject of analysis for sociologists, political scientists, anthropologists and social historians. However, there is not a consensus on a definition of "class" and the term has a wide range of sometimes conflicting meanings. In common parlance, the term "social class" is usually synonymous with "socio-economic class", defined as "people having the same social, economic, cultural, political or educational status", e.g., "the working class"; "an emerging professional class". However, academics distinguish social class and socioeconomic status, with the former referring to one's relatively stable sociocultural background and the latter referring to one's current social and economic situation and consequently being more changeable over time.The precise measurements of what determines social class in society has varied over time. Karl Marx thought "class" was defined by one's relationship to the means of production (their relations of production). His simple understanding of classes in modern capitalist society are the proletariat, those who work but do not own the means of production; and the bourgeoisie, those who invest and live off the surplus generated by the proletariat's operation of the means of production. This contrasts with the view of the sociologist Max Weber, who argued "class" is determined by economic position, in contrast to "social status" or "Stand" which is determined by social prestige rather than simply just relations of production. The term "class" is etymologically derived from the Latin classis, which was used by census takers to categorize citizens by wealth in order to determine military service obligations.In the late 18th century, the term "class" began to replace classifications such as estates, rank and orders as the primary means of organizing society into hierarchical divisions. This corresponded to a general decrease in significance ascribed to hereditary characteristics and increase in the significance of wealth and income as indicators of position in the social hierarchy.

Social democracy

Social democracy is a political, social and economic ideology that supports economic and social interventions to promote social justice within the framework of a liberal democratic polity and a capitalist economy. The protocols and norms used to accomplish this involve a commitment to representative and participatory democracy, measures for income redistribution and regulation of the economy in the general interest and welfare state provisions. Social democracy thus aims to create the conditions for capitalism to lead to greater democratic, egalitarian and solidaristic outcomes. Due to longstanding governance by social democratic parties and their influence on socioeconomic policy development in the Nordic countries, in policy circles social democracy has become associated with the Nordic model in the latter part of the 20th century.Social democracy originated as a political ideology that advocated an evolutionary and peaceful transition from capitalism to socialism using established political processes in contrast to the revolutionary approach to transition associated with orthodox Marxism. In the early post-war era in Western Europe, social democratic parties rejected the Stalinist political and economic model then current in the Soviet Union, committing themselves either to an alternative path to socialism or to a compromise between capitalism and socialism. In this period, social democrats embraced a mixed economy based on the predominance of private property, with only a minority of essential utilities and public services under public ownership. As a result, social democracy became associated with Keynesian economics, state interventionism and the welfare state while abandoning the prior goal of replacing the capitalist system (factor markets, private property and wage labor) with a qualitatively different socialist economic system.With the rise of popularity for neoliberalism and the New Right by the 1980s, most social democratic parties have incorporated Third Way ideology, which aims to fuse liberal economics with social democratic welfare policies.

Modern social democracy is characterized by a commitment to policies aimed at curbing inequality, oppression of underprivileged groups and poverty, including support for universally accessible public services like care for the elderly, child care, education, health care and workers' compensation. The social democratic movement often has strong connections with the labour movement and trade unions which are supportive of collective bargaining rights for workers as well as measures to extend decision-making beyond politics into the economic sphere in the form of co-determination for employees and other economic stakeholders.

Social media

Social media are interactive computer-mediated technologies that facilitate the creation and sharing of information, ideas, career interests and other forms of expression via virtual communities and networks. The variety of stand-alone and built-in social media services currently available introduces challenges of definition; however, there are some common features:

Social media are interactive Web 2.0 Internet-based applications.

User-generated content, such as text posts or comments, digital photos or videos, and data generated through all online interactions, is the lifeblood of social media.

Users create service-specific profiles for the website or app that are designed and maintained by the social media organization.

Social media facilitate the development of online social networks by connecting a user's profile with those of other individuals or groups.Users typically access social media services via web-based technologies on desktops and laptops, or download services that offer social media functionality to their mobile devices (e.g., smartphones and tablets). As users engage with these electronic services, they create highly interactive platforms through which individuals, communities, and organizations can share, co-create, discuss, and modify user-generated content or pre-made content posted online.

Networks formed through social media change the way groups of people interact and communicate. They "introduce substantial and pervasive changes to communication between organizations, communities, and individuals." These changes are the focus of the emerging fields of technoself studies. Social media differ from paper-based media (e.g., magazines and newspapers) and traditional electronic media such as TV broadcasting in many ways, including quality, reach, frequency, interactivity, usability, immediacy, and performance. Social media outlets operate in a dialogic transmission system (many sources to many receivers). This is in contrast to traditional media which operates under a mono-logic transmission model (one source to many receivers), such as a newspaper which is delivered to many subscribers, or a radio station which broadcasts the same programs to an entire city. Some of the most popular social media websites, with over 100 million registered users, include Facebook (and its associated Facebook Messenger), YouTube, WeChat, Instagram, QQ, QZone, Weibo, Twitter, Tumblr, Telegram, Reddit, Baidu Tieba, LinkedIn, LINE, Snapchat, Pinterest, Viber, and VK.

Observers have noted a range of positive and negative impacts of social media use. Social media can help to improve an individual's sense of connectedness with real or online communities, and can be an effective communication (or marketing) tool for corporations, entrepreneurs, non-profit organizations, advocacy groups, political parties, and governments.

Social networking service

A social networking service (also social networking site, or SNS or social media) is an online platform which people use to build social networks or social relations with other people who share similar personal or career interests, activities, backgrounds or real-life connections.

The social network is distributed across various computer networks. The social networks are inherently computer networks, linking people, organization, and knowledge. Social networking services vary in format and the number of features. They can incorporate a range of new information and communication tools, operating on desktops and on laptops, on mobile devices such as tablet computers and smartphones. They may feature digital photo/video/sharing and "web logging" diary entries online (blogging). Online community services are sometimes considered social-network services by programmers and users, though in a broader sense, a social-network service usually provides an individual-centered service whereas online community services are group-centered. Defined as "websites that facilitate the building of a network of contacts in order to exchange various types of content online," social networking sites provide a space for interaction to continue beyond in person interactions. These computer mediated interactions link members of various networks and may help to both maintain and develop new social ties.Social networking sites allow users to share ideas, digital photos and videos, posts, and to inform others about online or real-world activities and events with people in their network. While in-person social networking – such as gathering in a village market to talk about events – has existed since the earliest development of towns, the Web enables people to connect with others who live in different locations, ranging from across a city to across the world. Depending on the social media platform, members may be able to contact any other member. In other cases, members can contact anyone they have a connection to, and subsequently anyone that contact has a connection to, and so on. The success of social networking services can be seen in their dominance in society today, with Facebook having a massive 2.13 billion active monthly users and an average of 1.4 billion daily active users in 2017. LinkedIn, a career-oriented social-networking service, generally requires that a member personally know another member in real life before they contact them online. Some services require members to have a preexisting connection to contact other members.

The main types of social networking services contain category places (such as age or occupation or religion), means to connect with friends (usually with self-description pages), and a recommendation system linked to trust. One can categorize social-network services into four types:

socializing social network services used primarily for socializing with existing friends (e.g., Facebook)

online social networks are decentralized and distributed computer networks where users communicate with each other through internet services.

networking social network services used primarily for non-social interpersonal communication (e.g., LinkedIn, a career- and employment-oriented site)

social navigation social network services used primarily for helping users to find specific information or resources (e.g., Goodreads for books)There have been attempts to standardize these services to avoid the need to duplicate entries of friends and interests (see the FOAF standard). A study reveals that India recorded world's largest growth in terms of social media users in 2013.

A 2013 survey found that 73% of U.S. adults use social-networking sites.

Social science

Social science is a category of academic disciplines, concerned with society and the relationships among individuals within a society. Social science as a whole has many branches. These social sciences include, but are not limited to: anthropology, archaeology, communication studies, economics, history, human geography, jurisprudence, linguistics, political science, psychology, public health, and sociology. The term is also sometimes used to refer specifically to the field of sociology, the original "science of society", established in the 19th century. For a more detailed list of sub-disciplines within the social sciences see: Outline of social science.

Positivist social scientists use methods resembling those of the natural sciences as tools for understanding society, and so define science in its stricter modern sense. Interpretivist social scientists, by contrast, may use social critique or symbolic interpretation rather than constructing empirically falsifiable theories, and thus treat science in its broader sense. In modern academic practice, researchers are often eclectic, using multiple methodologies (for instance, by combining both quantitative and qualitative research). The term "social research" has also acquired a degree of autonomy as practitioners from various disciplines share in its aims and methods.


Socialism is a range of economic and social systems characterised by social ownership of the means of production and workers' self-management, as well as the political theories and movements associated with them. Social ownership can be public, collective or cooperative ownership, or citizen ownership of equity. There are many varieties of socialism and there is no single definition encapsulating all of them, with social ownership being the common element shared by its various forms.Socialist systems are divided into non-market and market forms. Non-market socialism involves the substitution of factor markets and money with engineering and technical criteria based on calculation performed in-kind, thereby producing an economic mechanism that functions according to different economic laws from those of capitalism. Non-market socialism aims to circumvent the inefficiencies and crises traditionally associated with capital accumulation and the profit system. By contrast, market socialism retains the use of monetary prices, factor markets and in some cases the profit motive, with respect to the operation of socially owned enterprises and the allocation of capital goods between them. Profits generated by these firms would be controlled directly by the workforce of each firm, or accrue to society at large in the form of a social dividend. The socialist calculation debate concerns the feasibility and methods of resource allocation for a socialist system.

Socialist politics has been both internationalist and nationalist in orientation; organised through political parties and opposed to party politics; at times overlapping with trade unions, and at other times independent and critical of unions; and present in both industrialised and developing nations. Originating within the socialist movement, social democracy has embraced a mixed economy with a market that includes substantial state intervention in the form of income redistribution, regulation, and a welfare state. Economic democracy proposes a sort of market socialism where there is more decentralised control of companies, currencies, investments, and natural resources.

The socialist political movement includes a set of political philosophies that originated in the revolutionary movements of the mid-to-late 18th century and out of concern for the social problems that were associated with capitalism. By the late 19th century, after the work of Karl Marx and his collaborator Friedrich Engels, socialism had come to signify opposition to capitalism and advocacy for a post-capitalist system based on some form of social ownership of the means of production. By the 1920s, social democracy and communism had become the two dominant political tendencies within the international socialist movement. By this time, socialism emerged as "the most influential secular movement of the twentieth century, worldwide. It is a political ideology (or world view), a wide and divided political movement" and while the emergence of the Soviet Union as the world's first nominally socialist state led to socialism's widespread association with the Soviet economic model, some economists and intellectuals argued that in practice the model functioned as a form of state capitalism or a non-planned administrative or command economy. Socialist parties and ideas remain a political force with varying degrees of power and influence on all continents, heading national governments in many countries around the world. Today, some socialists have also adopted the causes of other social movements, such as environmentalism, feminism and progressivism. In 21st century America, the term socialism, without clear definition, has become a pejorative used by conservatives to taint liberal and progressive policies, proposals, and public figures.


Sociology is the scientific study of society, patterns of social relationships, social interaction, and culture of everyday life. It is a social science that uses various methods of empirical investigation and critical analysis to develop a body of knowledge about social order, acceptance, and change or social evolution. While some sociologists conduct research that may be applied directly to social policy and welfare, others focus primarily on refining the theoretical understanding of social processes. Subject matter ranges from the micro-sociology level of individual agency and interaction to the macro level of systems and the social structure.The different traditional focuses of sociology include social stratification, social class, social mobility, religion, secularization, law, sexuality, gender, and deviance. As all spheres of human activity are affected by the interplay between social structure and individual agency, sociology has gradually expanded its focus to other subjects, such as health, medical, economy, military and penal institutions, the Internet, education, social capital, and the role of social activity in the development of scientific knowledge.

The range of social scientific methods has also expanded. Social researchers draw upon a variety of qualitative and quantitative techniques. The linguistic and cultural turns of the mid-20th century led to increasingly interpretative, hermeneutic, and philosophic approaches towards the analysis of society. Conversely, the end of the 1990s and the beginning of the 2000s have seen the rise of new analytically, mathematically, and computationally rigorous techniques, such as agent-based modelling and social network analysis.Social research informs politicians and policy makers, educators, planners, legislators, administrators, developers, business magnates, managers, social workers, non-governmental organizations, non-profit organizations, and people interested in resolving social issues in general. There is often a great deal of crossover between social research, market research, and other statistical fields.


Twitter () is an American online news and social networking service on which users post and interact with messages known as "tweets". Tweets were originally restricted to 140 characters, but on November 7, 2017, this limit was doubled for all languages except Chinese, Japanese, and Korean. Registered users can post, like, and retweet tweets, but unregistered users can only read them. Users access Twitter through its website interface, through Short Message Service (SMS) or its mobile-device application software ("app"). Twitter, Inc. is based in San Francisco, California, and has more than 25 offices around the world.Twitter was created in March 2006 by Jack Dorsey, Noah Glass, Biz Stone, and Evan Williams and launched in July of that year. The service rapidly gained worldwide popularity. In 2012, more than 100 million users posted 340 million tweets a day, and the service handled an average of 1.6 billion search queries per day. In 2013, it was one of the ten most-visited websites and has been described as "the SMS of the Internet". As of 2018, Twitter had more than 321 million monthly active users. Since 2015 Twitter has been a hotbed of debates and news covering politics of the United States. During the 2016 U.S. presidential election, Twitter was the largest source of breaking news on the day, with 40 million election-related tweets sent by 10:00 p.m. (Eastern Time) that day. It was also a source of information on Brett Kavanaugh's Supreme Court nomination and the 2018 United States midterm elections.
