Geographically, California's North-South midway point lies at exactly 37° 9' 58.23" latitude, around 11 miles (18 km) south of San Jose; however, this does not coincide with the popular use of the term. When the state is divided into two areas (northern and southern California), the term southern California usually refers to the 10 southernmost counties of the state. This definition coincides neatly with the county lines at 35° 47′ 28″ North latitude, which form the northern borders of San Luis Obispo, Kern, and San Bernardino counties.
