Population density is the average number of people per unit of land area. In the U.S., the most common unit of population density is persons per square mile. The land area measurement excludes lakes and other water areas within.
Small area estimates program: GIS shapefiles for select census geographic areas and other areas of statewide significance. Includes annual population and housing estimates from 2010 onwards.
These detailed demographic profiles are based on the 2010 Census Summary File 2 product which contains detailed demographic information for up to 331 different race/ethnic groups (250 in the case of Washington state). Summary File 2 includes information on age, sex, households, families, relationship to householder, housing units, and group quarters. Data are available for geographic entities that have at least 100 persons in a specific race/ethnic group.
All race/ethnic groups that meet the minimum population threshold of 100 persons are included in each demographic profile.
An asterisk (*) denotes that the area does not meet the minimum population threshold of 100 persons for any single race/ethnic group.
