Central California is generally thought of as the middle third of the state, north of Southern California, which includes Los Angeles, and south of Northern California, which includes San Francisco. 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), part of 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 Sierra is Eastern California. The largest cities in the region (over 50,000 population), from most to least populous, are Fresno, Bakersfield, Stockton, Modesto, Salinas, Visalia, Clovis, Santa Maria, Merced, Turlock, Madera, Lodi, Tulare, Porterville, Hanford and Delano. Over time, droughts and wildfires have increased in frequency and become less seasonal and more year-round, further straining the region's water security.
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. 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 and Sacramento 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.
