 The U.S. 1850 California Census asks state of birth of all residents and finds about 7300 residents that were born in California.The San Francisco, Contra Costa and Santa Clara county U.S. censuses were lost or burned in one of San Francisco's many fires.Adding the approximate 200 Hispanics in San Francisco (1846 directory) and an unknown (but small as shown in 1852 CA Census recount) number of Hispanics in Contra Costa and Santa Clara county in 1846 gives less than 8,000 Hispanics statewide in 1846 before hostilities commenced.
