(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 http://www.ofm.wa.gov/pop/smallarea/default.asp#estimates

• All maps are for individual Water Resource Inventory Areas (WRIA).

• GIS population data available from Washington State Office of Financial Management

• Population and housing estimates for WRIA's from OFM SMALL_AREA

• All maps are formatted to the same page size either 8.5 x 11 or 11 x 8.5 inches and can be printed up to 11x14 page size without loss of resolution.

• All population density maps have been produced with a "no color", zero population area background. This facilitates printing on clear acetate so the maps can be used for "overlay" purposes with the Major Public Lands map series map on this web site. If you use transparencies, remember to select paper type as "transparency" on your printer!
