This article includes a sortable table of the 50 United States, the District of Columbia, and territories ordered by population density. Population density is calculated as resident population divided by total land area. Resident population is from the United States Census Bureau estimates for July 1, 2011, and total land area is also from the Census Bureau.
The population density of the United States is relatively low compared to many other developed countries due to its size and its colonial history. For example, the population density of the U.S. is one twelfth that of the Netherlands, and one fifteenth that of South Korea (as of 2010).
