San Bernardino County, California is the largest county in the contiguous United States by area and the fifth-most populous in California. Encompassing over 20,000 square miles of diverse terrain from the Mojave Desert to the San Bernardino Mountains, it is a region of significant economic, historical, and cultural importance. The county seat and largest city is San Bernardino, with other major population centers including Fontana, Rancho Cucamonga, and Victorville.

History

The area has been inhabited for millennia by indigenous peoples, including the Serrano, Cahuilla, and Chemehuevi. Spanish exploration began with the expeditions of Francisco Garcés and the establishment of the Mission San Gabriel Arcángel in 1771. In 1810, the Rancho San Bernardino was granted, and later, the Mormon Battalion established the San Bernardino settlement in 1851. The county was officially formed in 1853 from parts of Los Angeles County. Key historical events include the construction of the Atchison, Topeka and Santa Fe Railway through Cajon Pass, the Gold Rush boom in the Holcomb Valley, and the massive industrial growth spurred by World War II, particularly at the Kaiser Steel plant in Fontana.

Geography

The county's vast geography includes the densely populated Inland Empire region in the southwest and expansive desert areas. Major mountain ranges are the San Bernardino Mountains, home to San Gorgonio Mountain—the highest peak in Southern California—and the San Jacinto Mountains. Significant desert features include the Mojave Desert, with landmarks like Joshua Tree National Park, the Twentynine Palms Marine Corps Base, and the Calico Early Man Site. Important water bodies are the Mojave River, the Santa Ana River, and Big Bear Lake. The county borders Riverside County, Los Angeles County, Kern County, Inyo County, and the states of Nevada and Arizona.

Demographics

According to the 2020 United States Census, the population exceeds 2.1 million residents. The demographic composition is highly diverse, with significant Hispanic or Latino communities, alongside large White non-Hispanic, African American, and Asian American populations. Major cities contributing to this diversity include Ontario, Rialto, and Chino. The county is part of the Los Angeles metropolitan area and has seen substantial growth in the High Desert regions around Victorville and Hesperia.

Economy

The economy is driven by logistics, manufacturing, healthcare, and tourism. It is a national logistics hub, centered around Ontario International Airport and major rail corridors served by the BNSF Railway and Union Pacific Railroad. Key employers include Amazon, Stater Bros., Loma Linda University Medical Center, and the San Manuel Band of Mission Indians' enterprise. The March Air Reserve Base and Fort Irwin National Training Center are significant federal installations. Tourism draws visitors to destinations like Big Bear Lake, Lake Arrowhead, Joshua Tree National Park, and the Route 66 corridor.

Government and politics

The county is governed by a five-member Board of Supervisors and administered by a County Administrative Officer. Key law enforcement agencies are the San Bernardino County Sheriff's Department and the San Bernardino Police Department. The county is represented in the California State Legislature by members such as those from the 23rd State Senate district and multiple California State Assembly districts. Federally, it is split among several U.S. House districts, including those represented by figures like Pete Aguilar and Ken Calvert. Voter registration has historically leaned Republican, though recent elections have become more competitive.

Culture and recreation

The county hosts numerous cultural institutions and events, including the San Bernardino County Museum in Redlands, the California Theatre of the Performing Arts, and the National Orange Show Festival. It is home to the Loma Linda University and the University of California, Riverside School of Medicine. Recreational opportunities abound in the San Bernardino National Forest, with skiing at Snow Valley Mountain Resort and hiking on the Pacific Crest Trail. Major venues include the Glen Helen Regional Park for concerts and the Auto Club Speedway in Fontana.
