The census tells us who we are and where we are going as a nation. The census helps our communities determine where to build everything from schools to supermarkets, and from homes to hospitals. It helps the government decide how to distribute funds and assistance to states and localities. It is also used to draw the lines of legislative districts and reapportion the seats each State holds in Congress.

Information about the 1820 Census

The fourth census was taken under the provisions of an act of March 14, 1820. The enumeration began on the first Monday of August, and was scheduled to conclude within 6 calendar months; however, the time prescribed for completing the enumeration was extended to September 1, 1821. The 1820 census act required that enumeration should be by an actual inquiry at every dwelling house, or of the head of every family within each district.

Data relating to manufactures were collected by the assistants, sent to the marshals, and then transmitted to the Secretary of State at the same time as the population returns. The report on manufactures presented the data for manufacturing establishments by counties, but the results were not summarized for each district and an aggregate statement was compiled as a result of incomplete returns.
