Central California is generally thought of as the middle third of the U.S. state of California, north of Southern California (which includes Los Angeles and San Diego) and south of Northern California (which includes San Francisco and San Jose). 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 Sacramento, Fresno, Stockton, Modesto, Elk Grove, Salinas, Visalia, Clovis, Tracy, Merced, Manteca, Turlock, Tulare, Madera, Lodi, Porterville, Santa Cruz, 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.
Central California being in the middle of the state starts at 36 parallel north (exact dividing line of Central and Southern California) and ending around 38°30 parallel north (Sacramento County)
