2000 Census results: King County population exceeds 1.7 million

On March 23, 2001 the U S Census Bureau released population counts from the 2000 Census that confirm Washington State and King County growth in recent years. In April 2000, the Census counted 1,737,034 persons in King County, up 15% from 1,507,300 in 1990. Washington State, with 5,894,000 persons, grew 21% during the 1990s, twice as fast as the nation. Seattle, the State's largest city, had a population of 563,374 up 9%. The new numbers, slightly larger than expected, underscored the public's excellent response to the 2000 Census, which apparently benefited from a better response rate than the 1990 Census. King County Executive Ron Sims chaired the local effort to encourage King County residents to answer the Census, helping to achieve a successful count.

The new population counts will serve a wide variety of public and private purposes. Total population numbers will be used for distribution of State and federal funds that will now accurately reflect the number and location of persons in King County. Later this year, redistricting of legislative districts and King County Council districts will ensure that "one person one vote" equity is maintained.
