A County of Counties

If there ever were a county to spotlight, it would be Los Angeles County, or as the official name calls it, the County of Los Angeles.

With over 10 million inhabitants, LA County is the largest county by population in the United States. And with an annual gross domestic product (GDP) of over $700 billion, it also the largest economic center of any other county in the U.S. (yes, even larger than New York County (Manhattan)).

If you were to compare the metropolitan area of Los Angeles County, it would be the 3rd largest metropolitan economy in the world. In fact, if you compared Los Angeles County's economy to a country, it would equal that of Switzerland.

Los Angeles County has 88 incorporated cities within its boundaries and -- at 4753 square miles -- is larger than the combined area of Rhode Island and Delaware. Los Angeles County is home to 1 out of 4 Californians and is one of the country's most diverse areas.

History of Los Angeles County

Several small groups of Native Americans first settled the area within present-day Los Angeles County hundreds of years before the first European contact in 1769. This was when Gaspar de Portola and a group of missionaries camped on the banks of the Los Angeles River. It was only two years later when Father Junipero Serra and a group of Spaniards founded the San Gabriel Mission. Ten years later, the Pobladores -- a group consisting of eleven families -- traveled from San Gabriel to establish a new pueblo. The settlement was called El Pueblo de la Reyna de Los Angeles. The English translation: the Pueblo of the Queen of the Angels.

After the Mexican-American War, the area came under U.S. control in 1847. After the signing of a treaty in 1848, Los Angeles and the rest of California were added to the American Territories.

Created at the time of California's statehood in 1850, Los Angeles County is one of the original counties in the state. When the county was originally founded, it included parts of many surrounding counties, and in 1852 stretched from the Pacific coast to the border of Nevada. As the population grew, portions of the county were subdivided into the current-day Bernardino County, Kern County, and eventually Orange County in 1889.


Los Angeles County is 4,753 square miles in size and comprises diverse geography. It borders 70 miles of coastline on the Pacific Ocean, mountain ranges, valleys, lakes, rivers, several islands, and deserts. Several rivers include the San Gabriel, Rio Hondo, Santa Clara River, and the Los Angeles River. The bordering mountain ranges are the Santa Monica and the San Gabriel Mountains. In the very northeastern part of the county, the western part of the Mojave Desert begins. If you like variety, nothing can match the range of geography you will find in Los Angeles County!

The main population areas of Los Angeles County can be found in the south and southwestern portion of the county. This includes the Los Angeles Basin, San Fernando Valley and San Gabriel Valley. Other population areas include the more northern Santa Clarita Valley and Pomona Valley.

The county is divided east to west by the San Gabriel Mountains, which provide a dramatic backdrop to the City of Los Angeles. The range is contained within the Angeles National Forest, a large U.S. National Forest and provides a wide range of recreational opportunites, such as camping, hiking and ski areas. The forest is home to all types of flora and fauna, including black bears, bobcats, gray foxes, bighorn sheep, cougars, rattlesnakes and coyotes.
