thumb|300px|Map of states shaded by population density (2020)
This is a list of the 50 states, the 5 territories, and the District of Columbia of the United States of America by population density, population size, and land area. It also includes a sortable table of density by states, territories, divisions, and regions by population rank and land area, and a sortable table for density by states, divisions, regions, and territories in square miles and square kilometers.
The population density of the United States is lower than that of many other countries because of the United States' large land area. Large swathes of land are sparsely populated in parts of the US, such as the east-to-west stretch extending from Minneapolis to the outskirts of Seattle, or the north-to-south expanse from northern Montana to southern New Mexico, excluding Denver and Albuquerque. For comparison, the population density of the U.S. is 1/15 that of South Korea and 1/12 that of India and the Netherlands. On the other hand, it is over 8 times higher than that of Canada and over 9 times higher than that of Australia.
States and territories by population density
Population density is defined as the population divided by land area. Data are from the US Census unless otherwise specified. Population data are for the year 2023 and area data are for the year 2010. Some population estimates for territories are from the United Nations Commission on Population and Development.
