This is a list of the largest cities in each U.S. state and territory by historical population, as enumerated every decade by the United States Census, starting with the 1790 Census. Data for the tables below is drawn from U.S. Census Bureau reports. For the 1990 Census and earlier, the primary resource is the 2005 Working Paper number POP-WP076. Post-1990 data, as well as data for territories, is drawn from the respective year's Census. Some locales may have pre-existed their first appearance in the U.S. Census, but such values are not included here, unless otherwise noted.
