San Joaquin County

San Joaquin County was one of the original United States counties of California, created in 1850 at the time of statehood. 

San Joaquin County comprises the Stockton-Lodi, CA Metropolitan Statistical Area, which is also included in the more inclusive San Jose-San Francisco-Oakland, CA Combined Statistical Area. The county is located in Northern California's Central Valley, just east of the less extensive nine-county San Francisco Bay Area region.
