1790 United States Census
The United States Census of 1790 was the first census of the whole United States. It recorded the population of the United States as of Census Day, August 2, 1790, as mandated by Article I, Section 2 of the United States Constitution and applicable laws. In the First Census, the population of the United States was enumerated to be 3,929,214.
Congress assigned responsibility for the 1790 census to the marshals of United States judicial districts under an act which, with minor modifications and extensions, governed census taking through 1840. "The law required that every household be visited, that completed census schedules be posted in 'two of the most public places within [each jurisdiction], there to remain for the inspection of all concerned...' and that 'the aggregate amount of each description of persons' for every district be transmitted to the president."
Loss of data
Although the Census was proved statistically factual, based on data collected, the records for several states (including: Delaware, Georgia, New Jersey, and Virginia) were lost sometime between 1790 and 1830. Almost one third of the original census data has been lost or destroyed since its original documentation. This includes the 1790 data from: Connecticut, Maine, Maryland, Massachusetts, New Hampshire, New York, North Carolina, Pennsylvania, Rhode Island, South Carolina, and Vermont; however, the validity and existence of most of this data can be confirmed in many secondary sources pertaining to the first census.
Census data included the name of the head of the family and categorized inhabitants as follows: free white males at least 16 years of age (to assess the country's industrial and military potential), free white males under 16 years of age, free white females, all other free persons (reported by sex and color), and slaves. Under the direction of the current Secretary of State Thomas Jefferson, marshals collected data from all thirteen states (Connecticut, Delaware, Georgia, Maryland, Massachusetts, New Hampshire, New Jersey, New York, North Carolina, Pennsylvania, Rhode Island, South Carolina, and Virginia), from the districts and territories that would become the states of Kentucky and Tennessee. Maine was at that time a part of Massachusetts, and so was included. The census was conducted in Vermont in 1791, after that state's admission to the Union as the 14th state earlier that year. (Vermont had already been functioning as a state without recognition since 1777, but was not admitted to the Union until March 1791.)
|District||Free white males of 16 years and upward, including heads of families.||Free white males under 16 years.||Free white females, including heads of families.||All other free persons.||Slaves.||Total.|
^ a: The census of 1790, published in 1791, reports 16 slaves in Vermont. Subsequently, and up to 1860, the number is given as 17. An examination of the original manuscript shows that there never were any slaves in Vermont. The original error occurred in preparing the results for publication, when 16 persons, returned as "Free colored," were classified as "Slave."
^ b: Corrected figures are 85,425, or 114 less than the figures published in 1790, due to an error of addition in the returns for each of the towns of Fairfield, Milton, Shelburne, and Williston, in the county of Chittenden; Brookfield, Newbury, Randolph, and Strafford, in the county of Orange; Castleton, Clarendon, Hubbardton, Poultney, Rutland, Shrewsburg, and Wallingford, in the county of Rutland; Dummerston, Guilford, Halifax, and Westminster, in the county of Windham; and Woodstock, in the county of Windsor.
^ c: Corrected figures are 59,096, or 2 more than figures published in 1790, due to error in addition
Impact on congressional apportionment
Based upon the population enumeration provided by the 1790 Census, the 2nd Congress passed legislation which increased the size of the United States House of Representatives from 69 seats in the 2nd Congress to 105 in the 3rd and apportioned those seats among the several states accordingly.
Both Secretary of State Thomas Jefferson and President George Washington expressed skepticism over the results, believing that the true population had been undercounted. If there was indeed an undercount, possible explanations for it include dispersed population, poor transportation links, limitations of contemporary technology, and individual refusal to participate.
No microdata from the 1790 population census are available, but aggregate data for small areas, together with compatible cartographic boundary files, can be downloaded from the National Historical Geographic Information System.
