San Bernardino County, California, officially the County of San Bernardino, is a county located in the southern portion of the U.S. state of California. As of the 2010 census, the population was 2,035,210,[6] making it the fifth-most populous county in California, and the 12th-most populous in the United States. The county seat is San Bernardino.[7]

San Bernardino County is included in the Riverside-San Bernardino-Ontario, CA Metropolitan Statistical Area, also known as the Inland Empire, as well as the Los Angeles-Long Beach, CA Combined Statistical Area.

With an area of 20,105 square miles, San Bernardino County is the largest county in the United States by area, although some of Alaska's boroughs and census areas are larger. It is larger than each of the nine smallest states, larger than the four smallest states combined, and larger than 71 different sovereign nations.

Located in southeast California, the thinly populated deserts and mountains of this vast county stretch from where the bulk of the county population resides in two Census County Divisions, some 1,422,745 people as of the 2010 Census, covering the 450 square miles (1,166 km2) south of the San Bernardino Mountains in San Bernardino Valley, to the Nevada border and the Colorado River.

Spanish Missionaries from Mission San Gabriel Arcángel established a church at the village of Politania in 1810. Father Francisco Dumetz named the church San Bernardino on May 20, 1810, after the feast day of St. Bernardino of Siena. The Franciscans also gave the name San Bernardino to the snowcapped peak in Southern California, in honor of the saint and it is from him that the county derives its name.[4] In 1819, they established the San Bernardino de Sena Estancia, a mission farm in what is now Redlands.

Following Mexican independence from Spain in 1821, Mexican citizens were granted land grants to establish ranchos in the area of the county. Rancho Jurupa in 1838, Rancho Cucamonga and El Rincon in 1839, Rancho Santa Ana del Chino in 1841, Rancho San Bernardino in 1842 and Rancho Muscupiabe in 1844.

Agua Mansa was the first town in what became San Bernardino County, settled by immigrants from New Mexico on land donated from the Rancho Jurupa in 1841.

Following the purchase of Rancho San Bernardino, and the establishment of the town of San Bernardino in 1851 by Mormon colonists, San Bernardino County was formed in 1853 from parts of Los Angeles County. Some of the southern parts of the county's territory were given to Riverside County in 1893.


The Arrowhead natural feature is the source of many local names and icons, such as Lake Arrowhead and the county's seal.

According to the U.S. Census Bureau, the county has a total area of 20,105 square miles (52,070 km2), of which 20,057 square miles (51,950 km2) is land and 48 square miles (120 km2) (0.2%) is water.[8] It is the largest county by area in California and the largest in the United States (excluding boroughs in Alaska). It is slightly larger than the states of New Jersey, Connecticut, Delaware and Rhode Island combined. It borders both Nevada and Arizona.

The bulk of the population, roughly two million, live in the roughly 480 square miles south of the San Bernardino Mountains adjacent to Riverside and in the San Bernardino Valley. Over 300,000 others live just north of the San Bernardino Mountains, agglomerating around Victorville covering roughly 280 square miles in Victor Valley, adjacent to Los Angeles County. Roughly another 100,000 people live scattered across the rest of the sprawling county.

The Mojave National Preserve covers some of the eastern desert, especially between Interstate 15 and Interstate 40. The desert portion also includes the cities of Needles next to the Colorado River and Barstow at the junction in Interstate 15 and Interstate 40. Trona is at the northwestern part of the county west of Death Valley. This national park, mostly within Inyo County, also has a small portion of land within the San Bernardino County. The largest metropolitan area in the Mojave Desert part of the county is Victor Valley, with the incorporated localities of Adelanto, Apple Valley, Hesperia, and Victorville. Further south, a portion of Joshua Tree National Park overlaps the county near Twentynine Palms. Additional places near and west of Twentynine palms include Yucca Valley, Joshua Tree, and Morongo Valley.

The mountains are home to the San Bernardino National Forest, and include the communities of Crestline, Lake Arrowhead, Running Springs, Big Bear City, Forest Falls, and Big Bear Lake.

The San Bernardino Valley is at the eastern end of the San Gabriel Valley. The San Bernardino Valley includes the cities of Ontario, Chino, Chino Hills, Upland, Fontana, Rialto, Colton, Grand Terrace, Rancho Cucamonga, San Bernardino, Loma Linda, Highland, Redlands, and Yucaipa.

Adjacent counties

National protected areas

There are at least 35 official wilderness areas in the county that are part of the National Wilderness Preservation System. This is the largest number of any county in the United States (although not the largest in total area). The majority are managed by the Bureau of Land Management, but some are integral components of the above listed national protected areas. Most of these wilderness areas lie entirely within the county, but a few are shared with neighboring counties (and two of these are shared with the neighboring states of Arizona and Nevada).

Except as noted, these wilderness areas are managed solely by the Bureau of Land Management and lie entirely within San Bernardino County:

Voter registration

Cities by population and voter registration


San Bernardino County is a county in which candidates from both major political parties have won in recent elections. The Democratic Party carried the county in 2000 by a plurality and in 2004 by a majority. The county is split between heavily Latino, middle-class, and Democratic areas and more wealthy conservative areas. The heavily Latino cities of Ontario and San Bernardino went for John Kerry in 2004, but with a relatively low voter turnout. In 2006, San Bernardino's population exceeded 201,000, and in 2004, only 42,520 votes were cast in the city; in 2006, strongly Republican Rancho Cucamonga had over 145,000 residents, of whom 53,054 voted.

According to the California Secretary of State, as of May 2009, there were 806,589 registered voters in San Bernardino County. Of those, 324,857 (40.28%) were registered Democrats, 306,203 (37.96%) were registered Republicans, with the remainder belonging to minor political parties or declining to state.[27]

On November 4, 2008 San Bernardino County voted 67% for Proposition 8, which amended the California Constitution to ban same-sex marriages.

Public safety

Law enforcement

SBC Sheriff's department operates a sizable fleet of helicopters. Shown here are a Bell 212 (foreground) and a Sikorsky S-61 at the air unit's Rialto Airport headquarters.

The county's primary law enforcement agency is the San Bernardino County Sheriff's Department. The department provides law enforcement services in the unincorporated areas of the county and in 14 contract cities, operates the county jail system, provides marshal services in the county superior courts, and has numerous other divisions to serve the residents of the county.

Sergeant Phil Brown of the San Bernardino County Sheriff's Department said the gangs are growing more violent in the farthest reaches of the county, including the High Desert. Racial tensions among Chicano gangs and African-American gangs have increased dramatically in the Inland Empire, affecting even the most rural areas. "It's getting out in more remote areas," Brown said. "They go gang against gang. There's more gang violence to the general public and it's becoming more random..."[28]

Fire rescue

The county operates the San Bernardino County Consolidated Fire District (commonly known as the San Bernardino County Fire Department). The department provides "all-risk" fire, rescue, and emergency medical services to all unincorporated areas in the county except for several areas served by independent fire protection districts, and several cities that chose to contract with the department.

Environmental quality

California Attorney General Jerry Brown sued the county in April 2007 under the state's environmental quality act for failing to account for the impact of global warming in the county's 25-year growth plan, approved in March. The Center for Biological Diversity, the Sierra Club and the Audubon Society also sued in a separate case. According to Brendan Cummings, a senior attorney for the plaintiffs: "San Bernardino has never seen a project it didn't like. They rubber-stamp development. It's very much of a frontier mentality." The plaintiffs want the county to rewrite its growth plan's environmental impact statement to include methods to measure greenhouse gases and take steps to reduce them.[37]

According to county spokesman David Wert, only 15% of the county is actually controlled by the county; the rest is cities and federal and state land. However, the county says it will make sure employment centers and housing are near transportation corridors to reduce traffic and do more to promote compact development and mass transit. The county budgeted $325,000 to fight the lawsuit.[37]

The state and the county reached a settlement in August 2007.[38] The county agreed to amend its general plan to include a Greenhouse Gas Emissions Reduction Plan, including an emissions inventory and reduction targets.
