1852 California State Census Now On Ancestry.com
California’s 1849 state constitution dictated that a census be taken in 1852, in 1855, and every 10 years after that. The 1852 census was the only one taken, but it proved to be an important count.
The results of this census can now be accessed on Ancestry.com at any branch of the San Mateo County Library (in the Research section of our website).
The gold rush would bring about 300,000 people to California between 1848 and 1854. The 1850 U.S. Federal Census tallied California’s population at 92,597. The 1852 California State Census count came in at 260,949 (neither census would include the entire Native American population).
Not only did the 1852 State Census provide a record of an additional 150,000 people, but records from three counties from the 1850 Federal Census - Contra Costa, San Francisco, and Santa Clara - that have since been lost or destroyed. In addition, the accuracy of the 1850 Federal Census was called into some question because of the rapid growth and mobility of the population at the time as miners poured into the state.
