List of counties in New Hampshire

This is a list of counties in New Hampshire.

There are ten counties in the U.S. state of New Hampshire. Five of the counties were created in 1769, when New Hampshire was still an English colony and not a state, during the first subdivision of the state into counties. The last counties created were Belknap County and Carroll County, in 1840.

The majority of New Hampshire's counties were named for prominent British or American people or geographic locations and features. Only one county's name originates in a Native American language: Coös County, named for an Algonquian word meaning "small pines".

The counties tend to be smaller in land area towards the southern end of the state, where New Hampshire population is concentrated, and larger in land area in the less populous north.[1][2]

The FIPS county code is the five-digit Federal Information Processing Standard (FIPS) code which uniquely identifies counties and county equivalents in the United States. The three-digit number is unique to each individual county within a state, but to be unique within the entire United States, it must be prefixed by the state code. This means that, for example, while Belknap County, New Hampshire is 001, Addison County, Vermont and Alachua County, Florida are also 001. To uniquely identify Belknap County, New Hampshire, one must use the state code of 33 plus the county code of 001; therefore, the unique nationwide identifier for Belknap County, New Hampshire is 33001. The links in the column FIPS County Code are to the Census Bureau Info page for that county.[3]

List of cities and towns in New Hampshire

New Hampshire is a state located in the Northeastern United States. This is a list of the 221 towns and 13 cities in the U.S. state of New Hampshire. New Hampshire is organized along the New England town model, where the state is nearly completely incorporated and divided into towns, some of which the state has designated as "cities". For each town/city, the table lists the county to which it belongs, its date of incorporation, its population according to the 2010 census, its form of government, and its principal villages. Cities are indicated in boldface. Cities and towns are treated identically under state law. Cities are just towns that dropped the town meeting form of government in favor of a city form by special act of the New Hampshire General Court. However, since 1979, changing the form of governance no longer confers city status. Towns may drop the town meeting by local vote and adopt a new charter for a representative government, such as a council-manager form, and retain their status as a town. Several of the higher-population towns have already done so.

Generally, government forms come in several varieties:

The standard form has a board of selectmen acting as the town executive, while the entire voting population of the town acts as the town legislature in a form known as a town meeting.

Some towns have adopted a town manager to act as the town executive, in those cases the board of selectmen acts as the town legislature, while town meetings are advisory in nature. This form functions as the council-manager municipal form

Other towns have abolished their boards of selectmen and replaced it with a town council, to form a council-manager system

Prior to 1979, to abolish the board of selectmen and open town meeting required the town to be rechartered by the state legislature as a city, whereby the city charter would establish a representative government for the town, usually a board of aldermen or city council and led by a mayor and/or city manager.Regardless of which form of government a municipality uses, and whether it calls itself a city or town, all cities and towns are treated identically by the state law.

New Hampshire also has a small number of townships, grants, gores and other unincorporated areas which are not part of any municipality. These are small and rare, and cover a small amount of the land and population of the state.
