1790 United States census in the context of "6th United States Congress"

The United States census (plural censuses or census) is a decennial census that is legally mandated by the Constitution of the United States. The first census after the American Revolution was taken in 1790 under Secretary of State Thomas Jefferson. There have been 24 federal censuses since that time. The census includes territories of the United States. The United States Census Bureau is responsible for conducting the census.

The most recent national census took place in 2020; the next census is scheduled for 2030. Since 2013, the Census Bureau began discussions on using technology to aid data collection starting with the 2020 census. In 2020, every household received an invitation to complete the census over the Internet, by phone or by paper questionnaire. For years between the decennial censuses, the Census Bureau issues estimates made using surveys and statistical models, in particular, the Population Estimates Program and American Community Survey.

The 3rd United States Congress was a meeting of the legislative branch of the United States federal government, consisting of the United States Senate and the United States House of Representatives. It met at Congress Hall in Philadelphia, Pennsylvania from March 4, 1793, to March 4, 1795, during the fifth and sixth years of George Washington's presidency.

The apportionment of seats in the House of Representatives was governed by the Apportionment Act of 1792 and based on the 1790 census. The Senate had a Pro-Administration majority, and the House had an Anti-Administration majority.

This list tracks and ranks the population of the top 10 largest cities and other urban places in the United States by decade, as reported by each decennial United States census, starting with the 1790 census. For 1790 through 1990, tables are taken from the U.S Census Bureau's "Population of the 100 Largest Cities and Other Urban Places in the United States: 1790 to 1990." For year 2000 rankings, data from the Census Bureau's tally of "Cities with 100,000 or More Population Ranked by Selected Subject" is used. The 2010 rankings are based on the 2010 census results.

The Census Bureau's definition of an "urban place" has included a variety of designations, including city, town, township, village, borough, and municipality. The top 10 urban areas in 1790 consisted of various places designated as cities, towns and townships. The top 10 urban areas in 2010 are all separate incorporated places.
