Statewide Connecticut Census records that exist are 1790, 1800, 1810, 1820, 1830, 1840, 1850, 1860, 1870, 1880, 1890 (fragment, see below), 1900, 1910, 1920, 1930 and 1940.

There are Industry and Agriculture Schedules 1850, 1860, 1870 and 1880. The Mortality Schedules for the years 1850, 1860, 1870 and 1880. The Union Veterans Schedules exist for 1890.

All of the federal census records for Connecticut are complete except for the 1890 census records. The Connecticut State Library holds microfilm or originals and indexes for each of those records.

There are also several records available through various Connecticut genealogical websites. The Connecticut State Library also has an index on file of a set of duplicate schedules for 1790-1850, which are located at the Connecticut State Archives.

That special set is not official and is not compiled in the same way as the official set, which means that it cannot be used to find a particular person. There is one key benefit of the special set, though. That benefit is that it doesn’t just list heads of households for 1850. Instead, it lists every member of each household.

Many different enumerations and population inventories for colonial Connecticut still exist today in various compilations. The Connecticut 1670 Census, for example, contains several freeman, probate, land, church and tax records.

It covers each of the colony’s heads of household from 1887 through 1673. However, it may not be entirely accurate, which means that it’s still important to cross-check that information against the source material.

The Grain Inventory for Windsor, Wethersfield and Hartford for 1669-1670 lists the bushels of corn and wheat in each family’s possession, as well as the number of people in the household and the name of the household’s head. The inventory doesn’t cover every single Connecticut resident, but it is an interesting and helpful genealogical record.

Age groups, races and sexes are listed in the 1756, 1762 and 1774 census records, but names are not.

State censuses were never taken for the state of Connecticut. However, the 1917 Military Census contained a list of all males between 20 and 30 years old in each town.

Some towns even extended that to the ages of 16 through 60. That same census listed nurses and other females with important occupations. Each person’s age, name, birthplace, occupation and dependents were listed. The census also noted whether or not a person was able bodied enough to do certain things.
