Spreading across the southern end of the California Central Valley, Kern County is the thirteenth-largest county by population in California. Its economy is heavily linked to agriculture and to petroleum extraction, and there is a strong aviation and space presence.
In the beginning, the area that became Kern County was dominated by mining in the mountains and in the desert. County government was created in 1866 with the county seat in the mining town of Havilah, in the mountains between Bakersfield and Tehachapi. Since 1874 the county seat has been the city of Bakersfield.
