California is a state located on the West Coast of the United States. It is by far the most populous U.S. state, and the third most extensive (after Alaska and Texas). It is home to the nation's second- and sixth-largest census statistical areas (Los Angeles Metropolitan Area and San Francisco Bay Area), and eight of the nation's fifty most populated cities (Los Angeles, San Diego, San Jose, San Francisco, Fresno, Sacramento, Long Beach and Oakland). The capital city is Sacramento.
California's diverse geography ranges from the Pacific Coast in the west, to the Sierra Nevada mountains in the east—from the Redwood–Douglas-fir forests of the northwest, to the Mojave Desert areas in the southeast. The center of the state is dominated by Central Valley, a major agricultural area. California contains both the highest and lowest points in the contiguous United States (Mount Whitney and Death Valley), and has the third-longest coastline of all states (after Alaska and Florida). Earthquakes are a common occurrence due to the state's location along the Pacific Ring of Fire: about 37,000 are recorded annually.
The name California once referred to a large area of North America claimed by Spain that included much of modern-day Southwestern United States and the Baja California peninsula. Beginning in the late 18th century, the area known as Alta California, comprising the California territory north of the Baja Peninsula, was colonized by the Spanish Empire as part of New Spain. In 1821, Alta California became a part of Mexico following its successful war for independence. Shortly after the beginning of the Mexican-American War in 1846, a group of American settlers in Sonoma declared an independent California Republic in Alta California. Though its existence was short-lived, its flag became the precursor for California's current state flag. American victory in the war led to the Treaty of Guadalupe Hidalgo, in which Mexico ceded Alta California to the United States. Western areas of Alta California became the state of California, which was admitted as the 31st state on September 9, 1850.
The California Gold Rush beginning in 1848 led to dramatic social and demographic change, with large scale immigration from the U.S. and abroad and an accompanying economic boom. Key developments in the early 20th century included the emergence of Los Angeles as the center of the American entertainment industry, and the growth of a large, state-wide tourism sector. The late 20th century saw the development of the technology and information sectors, punctuated by the growth of Silicon Valley. In addition to California's prosperous agricultural industry, other important contributors to its economy include aerospace, education, and manufacturing. If California were a country, it would be the eighth-largest economy in the world and the 35th most populous nation. At least half of the fresh fruit produced in the United States are cultivated in California, and it also leads in the production of vegetables.
Languages
As of 2005, 57.6% of California residents age five and older spoke English as a first language at home, while 28.2% spoke Spanish. In addition to English and Spanish, 2.0% spoke Filipino, 1.6% spoke Chinese (which included Cantonese [0.6%] and Mandarin [0.4%]), 1.4% spoke Vietnamese, and 1.1% spoke Korean as their mother tongue. In total, 42.4% of the population spoke languages other than English. California was historically one of the most linguistically diverse areas in the world, and is home to more than 70 indigenous languages derived from 64 root languages in 6 language families. About half of the indigenous languages are no longer spoken, and all of California's living indigenous languages are endangered. There are some efforts toward language revitalization, such as for the Karuk language.
The official language of California has been English since the passage of Proposition 63 in 1986. However, many state, city, and local government agencies still continue to print official public documents in numerous languages. For example, the California Department of Motor Vehicles offers the written exam for the standard C Class driver's license in 31 languages along with English, and the audio exam in 11 languages.
Transportation
California's vast terrain is connected by an extensive system of controlled-access highways ('freeways'), limited-access roads ('expressways'), and highways. California is known for its car culture, giving California's cities a reputation for severe traffic congestion. Construction and maintenance of state roads and statewide transportation planning are primarily the responsibility of the California Department of Transportation, nicknamed "Caltrans". The rapidly growing population of the state is straining all of its transportation networks, and California has some of the worst roads in the United States. The Reason Foundation's 19th Annual Report on the Performance of State Highway Systems ranked California's highways the third-worst of any state, with Alaska second, and Rhode Island first.
One of the state's more visible landmarks, the Golden Gate Bridge was completed in 1937. With its orange paint and panoramic views of the bay, this highway bridge is a popular tourist attraction and also accommodates pedestrians and bicyclists. It is simultaneously designated as U.S. Route 101, which is part of the El Camino Real (Spanish for Royal Road or King's Highway), and State Route 1, also known as the Pacific Coast Highway. Another of the seven bridges in the San Francisco Bay Area is the San Francisco – Oakland Bay Bridge (often abbreviated the "Bay Bridge"), completed in 1936. This bridge transports approximately 280,000 vehicles per day on two-decks, with its two sections meeting at Yerba Buena Island.
Los Angeles International Airport and San Francisco International Airport are major hubs for trans-Pacific and transcontinental traffic. There are about a dozen important commercial airports and many more general aviation airports throughout the state.
California also has several important seaports. The giant seaport complex formed by the Port of Los Angeles and the Port of Long Beach in Southern California is the largest in the country and responsible for handling about a fourth of all container cargo traffic in the United States. The Port of Oakland, fourth largest in the nation, handles trade from the Pacific Rim and delivers most of the ocean containers passing through Northern California to the entire USA.
The California Highway Patrol is the largest statewide police agency in the United States in terms of employment with over 10,000 employees. They are responsible for providing any police-sanctioned service to anyone on California's state maintained highways and on state property.
The California Department of Motor Vehicles is by far the largest in North America. By the end of 2009, the California DMV had 26,555,006 driver's licenses and ID cards on file. In 2010, there were 1.17 million new vehicle registrations in force.
Intercity rail travel is provided by Amtrak California, which manages the three busiest intercity rail lines in the U.S. outside the Northeast Corridor, all of which are funded by Caltrans. This service is becoming increasingly popular over flying and ridership is continuing to set records, especially on the LAX-SFO route. Integrated subway and light rail networks are found in Los Angeles (Metro Rail) and San Francisco (MUNI Metro). Light rail systems are also found in San Jose (VTA), San Diego (San Diego Trolley), Sacramento (RT Light Rail), and Northern San Diego County (Sprinter). Furthermore, commuter rail networks serve the San Francisco Bay Area (ACE, BART, Caltrain), Greater Los Angeles (Metrolink), and San Diego County (Coaster).
The California High-Speed Rail Authority was created in 1996 by the state to implement an extensive 700 mile (1127 km) rail system. Construction was approved by the voters during the November 2008 general election, a $9.95 billion state bond will go toward its construction. Nearly all counties operate bus lines, and many cities operate their own bus lines as well. Intercity bus travel is provided by Greyhound and Amtrak Thruway Coach.
In March 2011, California ranked as a top BEST state in the American State Litter Scorecard for overall effectiveness and quality of its public space cleanliness—-primarily roadway litter—from state and related debris removal efforts.
Cities, towns and counties
The state's local government is divided into 58 counties and 482 incorporated cities and towns; of which 460 are cities and 22 are towns. Under California law, the terms "city" and "town" are explicitly interchangeable; the name of an incorporated municipality in the state can either be "City of (Name)" or "Town of (Name)".
Sacramento became California's first incorporated city on February 27, 1850. San Jose, San Diego and Benicia tied for California's second incorporated city, each receiving incorporation on March 27, 1850. Jurupa Valley became the state's most recent and 482nd incorporated municipality on July 1, 2011.
The majority of these cities and towns are within one of five metropolitan areas. Sixty-eight percent of California's population lives in its three largest metropolitan areas, Greater Los Angeles Area, the San Francisco Bay Area, and the Riverside-San Bernardino Area. Although smaller, the other two large population centers are the San Diego and Greater Sacramento metro areas.
The state recognizes two kinds of cities: charter and general law. General law cities owe their existence to state law and are consequentially governed by it; charter cities are governed by their own city charters. Cities incorporated in the 19th century tend to be charter cities. All ten of the state's most populous cities are charter cities.
