This article shows U.S. Census totals for Hartford County, Connecticut, broken down by municipality, from 1900 to 2010.
Like most areas of New England, Hartford County is (and has been at all times since well before the 20th century) entirely divided into incorporated municipalities. There is no unincorporated territory.
There are three types of municipalities in Connecticut: towns, boroughs and cities. As in the other New England states, towns are the basic unit of municipal government.
Boroughs overlay towns and assume responsibility for some municipal services within their boundaries. Boroughs are not found in any of the other New England states, and are not very common in Connecticut today, although they were somewhat more numerous in the past. A number of boroughs have disincorporated over the years, choosing to revert to full town control.
Cities also overlay towns. This is different from the other New England states, where cities are a different type of municipality equivalent to a town (this difference is related to cities having originally developed in Connecticut from the borough model). Most current cities are coextensive with their parent town, however, such that the entire municipality functions as a city. In practice, these cities are really no different from cities in the other New England states.
It is also possible for a city in Connecticut to overlay part, but not all, of a town. There are currently only one or two examples, but it was a more common arrangement in the past. Many of today’s coextensive cities were non-coextensive at one time. As with boroughs, a number of non-coextensive cities have also disincorporated over the years, choosing to revert to full town control.
The main tables below show municipalities at the town level. For any census, adding up the totals for each town should yield the county total. In cases where a community encompassed a coextensive city, the tables in the New England Historical U.S. Census Totals series mark the community as a city. In cases where a town included a non-coextensive city, the total shown below represents the entire town, including but not limited to the city. A separate section follows with population totals for boroughs and non-coextensive cities.
For more information on the New England municipal system, see New England town.
1905 – New Britain became a coextensive city (Note: before this time, there had been a city of New Britain within, but not coextensive with, the town of New Britain)
1911 – Bristol became a coextensive city (Note: there had not previously been a city of Bristol within the town, although there had been a borough of Bristol)

Boroughs and Non-coextensive Cities
As of 1900, Hartford County contained two boroughs and one non-coextensive city:
The borough of Bristol, within the town of the same name
The borough of Southington, within the town of the same name
The city of New Britain, within the town of the same name
In addition to the above, there was a second city, Hartford, which had already been made coextensive with its parent town. A fourth borough, Farmington (within the town of the same name), was incorporated in 1901. The following changes have occurred since then:
1905 – The city of New Britain became coextensive with its parent town
1911 – The borough of Bristol became a city, and was made coextensive with its parent town
1921 – New borough of Unionville incorporated, within the town of Farmington
1947 – The boroughs of Farmington and Unionville disincorporated
1948 – The borough of Southington disincorporated
