US Demographic/Socio-Economic data: Census Bureau: 1800 Census

The Census Bureau's publications are changing, but their mission is the same - gather and disseminate demographic data on the population of the U.S.

1800 Census Data

           1800 Census Tables

Total U.S. Population Count: 5,308,483

As set out in the Constitution, the Congress wrote the law directing that the census be taken, appointing officers to take the census, and specifying what information was to be gathered. (Census Act of 1800)  

Information gathered:

  • Name of county, parish, township, town, or city where the family resides
  • Name of the Head of Family
  • Free white males by age (under 10 years, 10-15, 16-25,26-44, 45+)
  • Free white females by age  (under 10 years, 10-15, 16-25,25-44, 45+)
  • All other free persons, except Indians
  • Slaves
No microdata from the 1800 census of population are available. Aggregate data for small areas, together with compatible cartographic boundary files, can be downloaded from the National Historical Geographic Information System.

Thomas Jefferson, as President of the American Philosophical Society, sent a letter to Congress asking that the census be expanded for 1800. The Society asked that census takers gather information on:

  • the number of births, 
  • the number of persons aged 2, 5, 10, 16, 25, 30, 35, 40, 45, 50, 55, 60, 65, 70, 75, 80, 85, 90, 95, 100 in order to calculate the average life span of the people of the United States and to create population projections.
  • Nativity:
    •  the number of native citizens, 
    • citizens of foreign birth, 
    • and aliens. 
  • employment by profession: 
    • men in learned professions (such as clergymen, lawyers, physicians, teachers, and those employed in the fine arts), 
    • men working as merchants and traders (including bankers, insurers, brokers, and dealers of every kind),  
    • Marines
    • Craftsmen
    • Laborers in agriculture
    • Laborers of other description
    • Domestic Servants
    • Paupers
    • Persons of no particular calling, living on their income.


The census schedules (the actual written records of information from each household) were, by legal mandate, posted in "two of the most public places within [each jurisdiction] there to remain for the inspection of all concerned..." 

A complete set of the schedules, along with summary data for the counties, and, in some areas, for the towns, was filed with the State Department. In 1812, when the British burned the Capitol during the war, the schedules from many of the states were destroyed. Schedules for the following states survived: Connecticut, Delaware, District of Columbia, Maine, Maryland, Massachusetts, New Hampshire, New York, North Carolina, Pennsylvania, Rhode Island, South Carolina, and Vermont.   

Remaining records are in the United States National Archives. To view microfilm of released census schedules (all schedules more than 72 years old) contact the regional NARA center at Laguna Niguel. Digitized versions can be accessed through Ancestry.com.
