Imperial County, California
Imperial County is located on the southeast border of the U.S. state of California. As of the 2020 census, the population was 179,702, ranking as the least populous county in Southern California. The county seat and largest city is El Centro. Imperial is the most recent California county to be established, as it was created in 1907 out of the eastern half of San Diego County. Imperial County is located in the far southeast of California, in the Imperial Valley. It borders San Diego County to the west, Riverside County to the north, the U.S. state of Arizona to the east and the Mexican state of Baja California to the south. It includes the El Centro metropolitan statistical area and is part of the Southern California border region, the smallest but most economically diverse region in the state. Although this region is a desert, with high temperatures and low average rainfall of 3 inches (76 mm) per year, the economy is strongly based on agriculture. This is supported by irrigation, with water supplied wholly from the Colorado River via the All-American Canal. The Imperial Valley straddles the border between the United States and Mexico. Imperial County is strongly influenced by Mexican culture. Approximately 85% of the county's population is Hispanic, with the vast majority being of Mexican origin. It has the highest proportion of Hispanics of any county in California. The remainder of the population is predominantly non-Hispanic white, in addition to smaller African American, Native American, and Asian minorities.
