Statewide Census Records that exist for Washington are 1870, 1880, 1890 (fragment, see below), 1900, 1910, 1920, 1930 and 1940.
There are Industry and Agriculture Schedules 1870 and 1880; the Mortality Schedules for the years 1870 and 1880; and the Union Veterans Schedules for 1890.
Portions of Wyoming, Montana and what later turned into Idaho Territory were all included in the 1860 census. The Washington State Archives holds several microfilmed industrial and agricultural census records.
An index of the census for 1910 can be found on the website for the Washington GenWeb Project. The “Historical Records Search” database, contains a partial index of Washington’s censuses. The federal and state enumerations are some of the resources being used to compile those indexes.
Territorial and State Records
Although there were many censuses taken within Washington Territory, none of them included Native Americas. The Washington State Archives and regional branches of it have those schedules on microfilm.
The Washington State Library’s inter-library lending policy has led two two volumes of territorial census records on microfilm being available at the Suzzalo Library at the University of Washington.
