Territorial and State
Censuses were taken to track the rapid population growth as families came to Washington. Originally used to determine new counties, districts for elections and taxation, and even statehood, censuses are now a mainstay in genealogical research.

Online territorial censuses are available from:
 * Washington Digital Archives Collections (Free, indexes only) Censuses are listed by year (starting in 1847) with counties. Includes several federal census indexes.
 * Ancestry.com ($, indexes and images) For the list of years, scroll to About Washington State and Territorial Censuses, 1857-1892.

Census Microfilms are available from:
 * [ Washington State Archives]: See an online list of Washington Territorial Census Rolls
 * Family History Library: Search the FamilySearch catalog at the state and county levels.
