Los Angeles County

Los Angeles County. It is the most populous county in the United States, containing within its borders the nation's second-largest city, Los Angeles. Established in 1850 as one of California's original counties, its vast and diverse landscape stretches from the Pacific Ocean to the San Gabriel Mountains and the Mojave Desert. The county is a global hub for entertainment, international trade, technology, and culture, anchored by world-famous institutions and a dynamic, multicultural population.

Geography

The county encompasses a topographically diverse area of over 4,700 square miles, bordered by Ventura County to the west, Kern County to the north, San Bernardino County to the east, and Orange County to the southeast.

The county was officially formed in 1850, shortly after California achieved statehood. The late 19th century saw transformative events like the arrival of the Southern Pacific Railroad and the California oil rush, while the early 20th century was defined by the rise of the Hollywood film industry, the completion of the Los Angeles Aqueduct, and significant population growth following World War II.
