Population Density Maps

by Water Resource Inventory Areas (WRIA)

(select by clicking a map area)

Map Information:

The population density maps are produced from the Census 2000 Block GIS polygon data coverage and population tables. Population density values are averaged by square mile of Census block area. Census block areas having population totals of less then one ( < 1) are shown in white on the maps. Zero population, Major Public Land areas have been used as an additional overlay, also show in white. These areas include parks, designated forests, wilderness, military training sites, and wildlife refuges. Tribal reservations within WRIAs are delineated with an angled cross-hatch overlay. These maps are a watershed (WRIA) "view" and as such, no population value tables are available. 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 county and by Statewide Map .
