Unincorporated area

 counties also include smaller amounts.

The unincorporated territory in Coos County consists of 23 distinct entities, covering about 560 square miles (approximately 30% of the county’s land area). Six are townships (essentially, areas that were drawn up as “future towns” in the 18th century, but never attained a large enough permanent population to formally incorporate as towns). The other seventeen are an assortment of grants, locations, and purchases (tracts of land, typically smaller than a town, which were not included in any town when town boundaries were being drawn up in the 18th and 19th centuries). Most of the unincorporated territory in Coos County is in the mountainous north central, northeastern and southeastern parts of the county. Almost all territory in the western, southwestern and south central parts of the county is incorporated.

Due to the large extent of unorganized territory in Coos County, a separate section with detailed historical census totals for such areas follows the main tables below. Note that Wentworth's Location

 was incorporated as a town for many years, although it never dropped the word “location” from its name. In recent censuses, the population of the unorganized territory (including Wentworth's Location) has typically been between 100 and 200 residents.

There are two types of incorporated municipalities in New Hampshire, towns

Note that there is both a Bean’s Grant and a Bean’s Purchase.

The population of many of the unincorporated entities has historically been transitory, and some have rarely if ever reported any population at all. The only ones that have reported population in each census since 1900 are Dixville Township, Millsfield Township and Wentworth’s Location (bearing in mind that Wentworth’s Location was an incorporated town for many years prior to the 1960s). All three appear to have small but well-established population bases. Wentworth’s Location has reported a population of at least 37 in every post-1900 census. Dixville and Millsfield have consistently been in double figures throughout the same period (the only exceptions being Millsfield in 1960 and 1980); in both communities, a town clerk's office exist for the purpose of conducting elections for state and federal officials. In addition to those noted above, Pinkham’s Grant reported population in every census from 1930 to 1990, although its population exceeded 17 in only one census, and it reported no population in 2000.

Note: The 1920 Census reported population for a Hubbard Township, a Webster Township, and a Colebrook Academy Grant. The 1920 census reports also make reference to a Carlisle township, although it is not shown as having any population. None of these appear on the current roster of unincorporated entities in Coos County; it is unclear what happened to them. The 1930 census reports add the first three into the town of Pittsburg’s 1920 total. The 1900 and 1910 censuses reported population for a Dartmouth College Grant which has since been known as the Second College Grant
