基于美国分州人口密度数据（2000年数据，2011年数据）
根据人口密度的大小顺序将美国50个州依次顺序排列。表中的数字的单位是人/每平方千米。数据的来源是美国人口调查局2000年的统计。
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 the ratio of resident population divided by total land area. Resident population is from the United States Census Bureau estimates for July 1, 2011,[1] and total land area is also from the Census Bureau.[2]
The population density of the United States is relatively low compared to many other developed countries. For example, the population density of the U.S. is one twelfth that of theNetherlands, and one fifteenth that of South Korea (as of 2010).[3]
