A rural county is defined as a county with a population density of fewer than 100 persons per square mile or a county smaller than 225 square miles, as determined by the Office of Financial Management.
Several statutes use this definition, including but not limited to statutes referencing public facilities loans and grants, the coordination of community and economic development services, and excise taxes. As of 2025, there are 29 rural counties.
The definition of rural county is expanded such that a county with a population density of 100 persons per square mile or greater, with no city with a population greater than 45,000 persons, is also defined as a rural county.
(In support) This bill will allow certain counties like Cowlitz County with generally low population density, and with no large cities, to be considered rural counties. The bill creates a new category of rural county, and it takes a forward-thinking approach by putting a cap on how large the largest city may be in such a county. This bill will have a positive impact for economic development.
(Opposed) None.
Senator Jeff Wilson, prime sponsor.
