Central California is a subregion of Northern California, generally thought of as the middle third of the state, north of Southern California. It includes the northern portion of the San Joaquin Valley (which itself is the southern portion of the Central Valley, beginning at the Sacramento–San Joaquin River Delta), the Central Coast, the central hills of the California Coast Ranges, and the foothills and mountain areas of the central Sierra Nevada.
Central California is considered to be west of the crest of the Sierra Nevada. (East of the Sierras is Eastern California.) The largest cities (over 50,000 population) in the region are Fresno, Modesto, Salinas, Visalia, Clovis, Merced, Turlock, Madera, Tulare, Porterville, and Hanford.
Central California can have widely varying definitions depending on the context. Some divide the state by lines of latitude making northern, central and southern sections. Others divide by county lines or watershed boundaries. Some definitions include more of the San Joaquin Valley and even larger portions of the Central Valley. Some have less or none of Central Coast.
Generally the widest definition of central California is the middle third of the state by latitude.[ citation needed] The southern boundary of that area would be 35° 41', which nearly coincides with the county lines already used for the southern boundary that cross the state west-to-east below Monterey, Kings and Tulare Counties. The northern boundary of that area at 38° 51' crosses just north of the Sacramento metro area. However, the San Francisco Bay, Sacramento and Stockton metro areas are traditionally considered parts of Northern California, intuitively grouped together as the northern urban center within the state. That leaves the most accepted definitions of central California to the areas south of there.[ citation needed]
