Connecticut Census

Federal
Federal census records are found at the Family History Library, the National Archives, and other federal and state archives. The United States Research Outline provides more detailed information regarding these records.

The Family History Library has the U.S. federal censuses of Connecticut from 1790, 1800, 1810, 1820, 1830, 1840, 1850, 1860, 1870, 1880, 1900, 1910, 1920 to 1930. The 1890 census was destroyed.

The library has book, film, and microfiche indexes of the 1790, 1800, 1810, 1820, 1830, 1840, 1850, and 1860 censuses. The Connecticut State Library and the Family History Library also have an index to the entire 1790 to 1850 censuses (listed in the Family History Library Catalog under CONNECTICUT - CENSUS - INDEXES). The page numbers of this index do not always match those on microfilms at the National Archives and the Family History Library. A soundex (phonetic) index is available for part of the 1880 census and all of the 1900, 1920 and 1930 censuses.

Mortality schedules exist for 1850, 1860, 1870, and 1880. The schedules are at the Connecticut State Library and the Family History Library (FHL films 234536-37).

The Connecticut State Library also has a special military census taken in 1917.
