1830 United States census
The 1830 United States census, the fifth census undertaken in the United States, was conducted on June 1, 1830. The only loss of census records for 1830 involved some countywide losses in Massachusetts, Maryland, and Mississippi.
It determined the population of the 24 states to be 12,866,020, of which 2,009,043 were slaves. The center of population was about 170 miles (274 km) west of Washington, D.C. in present-day Grant County, West Virginia.
This was the first census in which a city—New York—recorded a population of over 200,000.
