Understanding Iowa Census Records
A census is a count and description of the population of a country, state, county, or city. Censuses are conducted to understand the population density, geographical distribution, as well as the makeup of the population in terms of age, sex, and race.

Iowa, with its present boundaries, officially achieved statehood in 1846. The 1856, 1885, 1895, 1905, 1915 and 1925 state censuses are the only census records enumerated of all counties of the state.

The first Federal Iowa census records begin in 1840 and there has been one every ten years since. The censuses through 1940 are available to the public. These counted the population as of the following dates:

1790-1820: First Monday in August 1830-1900: June 1 (June 2 in 1890) 1910: April 15 1920: January 1 1930: April 1 1940: April 1

Why use a census?
A well-indexed census is one of the easiest ways to locate where an ancestor's family lived and when they lived there. You can also use censuses to follow the changes in a family over time, and identify neighbors. These and other clues provided by censuses are important because they help find additional kinds of records about the family.
