It borders Oregon to the north, Nevada and Arizona to the east, and the Mexican state of Baja California to the south. With over 38.9 million residents[6] across a total area of approximately 163,696 square miles (423,970 km2),[12] it is the most populous U.S. state, the third-largest U.S. state by area, and the most populated subnational entity in North America.

The Greater Los Angeles and San Francisco Bay areas in California are the nation's second and fifth-most populous urban regions respectively. Greater Los Angeles has over 18.7 million residents and the San Francisco Bay Area has over 9.6 million residents.[13] Los Angeles is the state's most populous city and the nation's second-most populous city. San Francisco is the second-most densely populated major city in the country. Los Angeles County is the country's most populous county, and San Bernardino County is the nation's largest county by area. Sacramento is the state's capital city.


California's economy is the largest of any state within the United States, with a $3.6 trillion gross state product (GSP) as of 2022.[14] It is the largest sub-national economy in the world. If California were a sovereign nation, it would rank as the world's fifth-largest economy as of 2022,[15][16] just ahead of India and the United Kingdom,[17] as well as the 37th most populous.[18] The Greater Los Angeles area and the San Francisco area are the nation's second- and fourth-largest urban economies ($1.0 trillion and $0.6 trillion respectively as of 2020).[19] The San Francisco Bay Area Combined Statistical Area had the nation's highest gross domestic product per capita ($106,757) among large primary statistical areas in 2018,[20] and is home to four of the world's ten largest companies by market capitalization[21] and four of the world's ten richest people.[22]


Prior to European colonization, California was one of the most culturally and linguistically diverse areas in pre-Columbian North America, and the indigenous peoples of California constituted the highest Native American population density north of what is now Mexico. European exploration in the 16th and 17th centuries led to the colonization of California by the Spanish Empire. In 1804, it was included in Alta California province within the Viceroyalty of New Spain. The area became a part of Mexico in 1821, following its successful war for independence, but was ceded to the United States in 1848 after the Mexican–American War. The California Gold Rush started in 1848 and led to dramatic social and demographic changes, including the depopulation of indigenous peoples in the California genocide. The western portion of Alta California was then organized and admitted as the 31st state on September 9, 1850, as a free state, following the Compromise of 1850.


Notable contributions to popular culture, ranging from entertainment, sports, music, and fashion, have their origins in California. The state also has made substantial contributions in the fields of communication, information, innovation, education, environmentalism, entertainment, economics, politics, technology, and religion.[23][24][25] California is the home of Hollywood, the oldest and one of the largest film industries in the world, profoundly influencing global entertainment. It is considered the origin of hippie counterculture, blue jeans, the internet, the personal computer, Barbie, skateboarding, Mission burritos, and the fortune cookie, among other inventions.[26][27][28][29] The San Francisco Bay Area and the Greater Los Angeles Area are widely seen as the centers of the global technology and U.S. film industries, respectively. California's economy is very diverse.[30]


California's agricultural industry has the highest output of any U.S. state,[31][32][33] and is led by its dairy, almonds, and grapes.[34] With the busiest ports in the country (Los Angeles and Long Beach), California plays a pivotal role in the global supply chain, hauling in about 40% of all goods imported to the United States.[35] Slightly over 84 percent of the state's residents 25 or older hold a high school degree, the lowest high school education rate of all 50 states.[36] Despite a continuing exodus of businesses from Downtown San Francisco[37][38] and Downtown Los Angeles[39] since the COVID-19 pandemic, California still retains one of the largest number of Fortune 500 companies.[40]


The state's extremely diverse geography ranges from the Pacific Coast and metropolitan areas in the west to the Sierra Nevada mountains in the east, and from the redwood and Douglas fir forests in the northwest to the Mojave Desert in the southeast. Two-thirds of the nation's earthquake risk lies in California.[41] The Central Valley, a fertile agricultural area, dominates the state's center. California is well known for its warm Mediterranean climate along the coast and monsoon seasonal weather inland. The large size of the state results in climates that vary from moist temperate rainforest in the north to arid desert in the interior, as well as snowy alpine in the mountains. Droughts and wildfires are an ongoing issue for the state.[42]

The state's research university system is the University of California (UC). As of fall 2011, the University of California had a combined student body of 234,464 students.[287] There are ten UC campuses; nine are general campuses offering both undergraduate and graduate programs which culminate in the award of bachelor's degrees, master's degrees, and doctorates; there is one specialized campus, UC San Francisco, which is entirely dedicated to graduate education in health care, and is home to the UCSF Medical Center, the highest-ranked hospital in California.[288] The system was originally intended to accept the top one-eighth of California high school students, but several of the campuses have become even more selective.[289][290][291] The UC system historically held exclusive authority to award the doctorate, but this has since changed and CSU now has limited statutory authorization to award a handful of types of doctoral degrees independently of UC.

The (CSU) system has almost 430,000 students. The CSU (which takes the definite article in its abbreviated form, while UC does not) was originally intended to accept the top one-third of California high school students, but several of the campuses have become much more selective.[291][292] The CSU was originally authorized to award only bachelor's and master's degrees, and could award the doctorate only as part of joint programs with UC or private universities. Since then, CSU has been granted the authority to independently award several doctoral degrees (in specific academic fields that do not intrude upon UC's traditional jurisdiction).

California State University

The system provides lower-division coursework culminating in the associate degree, as well as basic skills and workforce training culminating in various kinds of certificates. (Fifteen California community colleges now award four-year bachelor's degrees in disciplines which are in high demand in their geographical area.[293]) It is the largest network of higher education in the U.S., composed of 112 colleges serving a student population of over 2.6 million.
