Growth Management Act county projections
Development of population projections for the Growth Management Act (GMA) is a shared responsibility.
As directed by state statute, OFM prepares a reasonable range of possible population growth for Washington counties participating in GMA. These population projections go out 20 years and are used in growth management planning.
County officials, also by law, are responsible for selecting a 20-year GMA planning target from within the range of high and low prepared by OFM.
Within each county, population planning targets for cities, towns, and unincorporated areas are worked out among the affected local jurisdictions as part of city and county planning processes.
OFM's role is limited to providing the range of projected county populations noted above. OFM does not maintain record of the specific planning targets chosen by each county nor does OFM develop sub-county population projects used by local jurisdictions for GMA planning. If you are interested in these data you can contact individual county planning agencies or the Local Government Division of the Department of Commerce at 360-725-3000.
For questions regarding OFM's 2007 GMA population projections, please contact Yi Zhao at 360-902-0592.
