The United States Census 1830 was the fifth census in the United States since 1790 . As a result of the census, a population of 12,866,020 inhabitants was determined for the USA on June 1, 1830, of which 2,009,043 were slaves . This census comprised a total of 24 states.
The data contain information on the name of the head of the family, the home address, number of free white people (men and women according to age groups as in the previous censuses), number of slaves and people of color according to age groups, blind (no age groups), deaf and feeble-minded people ( after three age groups) as well as foreigners.
The state population figures from the 10-year United States censuses are key to determining the number of representatives from those states in the United States House of Representatives . The adjustment is usually made in the next but one Congress after a census.
