List of United States cities by population density

The following is a list of incorporated places in the United States with a population density of over 10,000 people per square mile. As defined by the United States Census Bureau, an incorporated place is a place that has a self-governing local government and as such has been "incorporated" by the state it is in. Each state has different laws defining how a place can be incorporated. An "incorporated place" as recognized by the U.S. Census Bureau can designate a variety of places, such as a city, town, village, borough, and township.[lower-alpha 1]

The other type of place defined by the U.S. Census Bureau for statistical purposes are census-designated places. Census-designated places are distinct from incorporated places because they do not have a local government and thus depend on higher government bodies, such as a county, for governance. Census-designated places are defined as being in an unincorporated area. Census-designated places that have a population density of over 10,000 people per square mile are listed in a separate table below. The five boroughs of New York City, and the census-designated places of Puerto Rico and the Northern Mariana Islands that have densities over 10,000, are also listed in separate tables below.
