The 1820 United States census was the fourth census conducted in the United States. It was conducted on August 7, 1820. The 1820 census included six new states: Louisiana, Indiana, Mississippi, Illinois, Alabama and Maine. There has been a district wide loss of 1820 census records for Arkansas Territory, Missouri Territory,[1] and New Jersey.
The total population was determined to be 9,638,453, of which 1,538,022 were slaves. The center of population was about 120 miles (193 km) west-northwest of Washington in Hardy County, Virginia (now in West Virginia).
This was the first census in which any states recorded a population of over one million—New York, Virginia, and Pennsylvania—as well as the first in which a city recorded a population of over 100,000—New York. It was also the first census in which Baltimore was ranked as the country's second-most populous city. Thirdly, in this census and the 14 subsequent ones, New York was the most populous state until being superseded by California in the 1970 census.
