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.
This list generally refers only to the population of individual urban places within their defined limits at the time of the indicated census. Some of these places have since been annexed or merged into other cities. Other places may have expanded their borders due to such annexation or consolidation. For example, after the 1898 consolidation of New York City, the Census Bureau has defined all the boroughs within its city limits as one "urban place". Similarly, Philadelphia's population has included the census counts within both the former urban areas of Northern Liberties, Pennsylvania and Southwark, Pennsylvania ever since Philadelphia's 1854 consolidation.
When the United States first became a country in 1776, Philadelphia was its most populous city. By the time the first U.S. census count was completed in 1790, New York City had already grown to be 14% more populous than Philadelphia (though Philadelphia still had the larger metropolitan population in 1790). Note that, in 1790, New York City consisted solely of Manhattan, and that Philadelphia did not include Northern Liberties, which is now within its city limits.

1950 was a watershed year for many cities in the United States. Many cities in the country peaked in population, and began a slow decline caused by suburbanization associated with pollution, congestion, and increased crime rates in inner cities, while the improved infrastructure of the Eisenhower Interstate System more easily facilitated car commutes and so-called white flight of the white middle class. The G.I. Bill made available low interest loans for returning World War II veterans seeking more commodious housing in the suburbs. Although populations within city limits dropped in many American cities, the metropolitan populations of most cities continued to increase greatly.

Seven of the country's ten largest cities in 2010 were located in the Sun Belt region of the south and west, all of which have far lower population density than their earlier top-ranking counterparts.
