The California State Library is a repository for the microfilm of California original federal censuses. The California State Archives (see California Archives, Libraries, and Societies) holds the original state copies for the federal 1860 and 1880 population schedules. Both repositories and the California Genealogical Society have microfilm copies of the state’s federal censuses.

Missing from the 1850 federal census are the population schedules for Contra Costa, San Francisco, and Santa Clara counties, making the 1852 state census (see below) even more useful.

Mission and State

Censuses were taken for the following missions: San Carlos (1796), San Luis Obispo (1797, 1798), San Antonio (1798), and Soledad (1798). They are all in original form at the California State Archives. They have been reprinted in Historical Society of Southern California Quarterly, volumes 41–43.

The California Constitution of 1849 provided for a census of the state population in the years 1852 and 1855 and each succeeding ten years thereafter. The census of 1852, similar to the 1850 federal census but using an additional column showing the prior residence of each person, was the only one actually taken. The original returns for 1852 are in the California State Archives with microfilm at the California State Library and the FHL. The constitution was altered in 1879 to provide for the use of the federal census in the matter of apportioning the state for legislative representation.

A few cities and towns have special censuses for California through the twentieth century. The California State Archives has a listing of its holdings in this category.
