How To Use The Record
The U.S. federal census is the best source to quickly identify a family group and residence. Use the place of residence, and the birth state for each person along with his or her age to search for other record types. The census identifies other persons in the household and how they are related. The census may identify persons for whom other records do not exist.

Record History
Federal census takers were asked to record information about all those who were in each household on the census day, which was 1 June. A census taker might have visited a house on a later date, but the information he collected was supposed to be about the people who were in the house on the census day. The basic census enumeration unit was the county. Each county was divided into enumeration districts, one for each enumerator. The completed forms were sent to the Census Office in the Commerce Department in Washington D.C. The 1870 census covers 80-90% of the population.

Why the Record Was Created
The U.S. federal census was taken at the beginning of every decade to apportion the number of representatives that a state could send to the House of Representatives in Congress. In the absence of a national system of vital registration, many vital statistics and personal questions were asked to provide a statistical profile of the nation and its states.

Record Reliability
Federal censuses are usually reliable, depending on the knowledge of the informant and the care of the census enumerator. Information may have been given to a census taker by any member of the family or by a neighbor. Some information may have been incorrect or deliberately falsified.
