Stanislaus County is a county located in the Central Valley of the U.S. state of California. As of the 2010 census, the population was 514,453. The county seat is Modesto.
Stanislaus County comprises the Modesto Metropolitan Statistical Area.
Stanislaus County was formed from part of Tuolumne County in 1854. The county seat was first situated at Adamsville, then moved to Empire in November, La Grange in December, and Knights Ferry in 1862, and was definitely fixed at the present location in Modesto in 1871.
As the price of housing has increased in the San Francisco Bay Area, many people who work in the southern reaches of the Bay Area have opted for the longer commute and moved to Stanislaus County for the relatively affordable housing.
