1820 United States Census
Population schedules consisted of large sheets with rows and columns. The schedules were arranged by place, such as township or post office. The places were not filed in any particular order. The arrangement of families on a schedule is normally in the order in which the enumerator visited the households. The original schedules are well preserved at the National Archives in Washington, D.C. They were microfilmed in the 1950s and 1960s. The schedules for some counties in varying censuses are missing.
Federal census takers were asked to record information about every person who was in each household on the census day, which was the first Monday in August for 1820. 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 Commerce Department's Census Office in Washington, D.C.
This census (1820) provides names for heads of household, for about 10 to 15 percent of the population, and provides only a number count for the others.
