Population Density Maps

(select by clicking a County area)

Map Information:

The population density maps are produced from the Census 2010 Block GIS polygon data coverage and population tables. Census block areas are reduced in size where they overlap public lands and government trust areas (Major Public Lands) and commercial forest land (parcel Land Use 2010). Population density values are then averaged by square mile of remaining census block area. Census block areas having population totals of zero are shown in white on the maps as are Major Public Land areas and commercial forests. These areas include parks, designated forests, wilderness, military training sites, and wildlife refuges. Tribal reservations within counties are delineated with an angled cross-hatch overlay. County and city population totals can be obtained from the Washington State Office of Financial Management (OFM) at

Please note that the population density maps are also available by Water Resource Inventory Areas (WRIA).
