Population density and land area criteria used for rural area assistance and other programs

In 1999, RCW 82.14.370 was revised to include a rural county definition based on population density. In this legislation, "rural county" was defined as"… a county with a population density less than 100 persons per square mile." Subsequent legislation expanded the definition to include"... a county smaller than two hundred twenty-five square miles." Several statutes now use this definition for tax and other assistance programs.

Counties with a population density less than 100 persons per square mile or counties smaller than 225 square miles as of April 1, 2019
