Riverside County is a large county in Southern California. As of 2020, over 2.4 million people live here. This makes it the fourth-most populated county in California and the 10th-most populated in the whole United States. The county is named after the city of Riverside, which is its main city and where the county government is located.
Riverside County is part of a larger area called the Inland Empire. This area also includes San Bernardino and Ontario. The county stretches from the greater Los Angeles area all the way to the Arizona border.
The western part of the county has a mild, Mediterranean climate with lots of chaparral plants. But as you move east, the land becomes mostly desert or mountains. A big part of Joshua Tree National Park is in Riverside County. Many popular resort cities like Palm Springs, Indio, and Coachella are found in the desert area called the Coachella Valley.
Many people have moved to Riverside County from the Los Angeles metropolitan area and San Diego metropolitan area. They come for more affordable homes. Cities like Temecula and Murrieta have grown a lot because of this.

A Look Back: History of Riverside County
Early People of the Land

Long before Europeans arrived, different groups of Native American people lived in the valleys, mountains, and deserts of what is now Riverside County. These groups included the Serrano, Payómkawichum, Mohave, Cupeno, Chemehuevi, Cahuilla, and Tongva tribes. For example, the Cahuilla people traditionally lived in the inland valleys of the Santa Rosa and San Jacinto Mountains, and the desert around the Salton Sink.
Spanish and Mexican Times
The first European settlement in the area was a farm called an estancia at the Luiseño village of Temescal. This farm belonged to the Mission San Luis Rey de Francia. In 1819, a man named Leandro Serrano was allowed to use the land for farming and raising animals. He started Rancho Temescal.
Later, in 1821, Mexico became independent from Spain. The San Gabriel Mission continued to grow and started Rancho San Gorgonio in 1824. This ranch was one of the Mission's most important and farthest outposts. It covered most of the San Gorgonio Pass area today. After Mexico took over the mission lands in 1833, many large ranches were created across the state, including several in what is now Riverside County.
Becoming Part of the United States
When California first became a state in 1850, the area that is now Riverside County was split between Los Angeles County and San Diego County. In 1853, San Bernardino County was created from the eastern part of Los Angeles County.
How Riverside County Was Formed
Between 1891 and 1893, people tried to create new counties in Southern California. Finally, a plan to create Riverside County was approved on March 11, 1893. The new county was made from parts of San Bernardino County and San Diego County. On May 2, 1893, most voters agreed to form Riverside County and chose the city of Riverside as the county seat. Riverside County officially began on May 9, 1893.
The county is also home to the March Air Reserve Base. This is one of the oldest airfields used by the United States military. It started in 1918 as a training field during World War I. It was renamed March Field and became a very important base during World War II and the Cold War. Today, it is a major base for the Air Force Reserve.
Riverside County was also important during the Civil Rights Movement. Many people, including Cesar Chavez who fought for farm workers' rights, visited the area.
Native American tribes in Riverside County have also been a focus of modern gaming businesses. In the 1980s, the county tried to stop small bingo games run by the Morongo Band of Cahuilla Mission Indians and the Cabazon Band of Mission Indians. The tribes worked together and won their case in the U.S. Supreme Court in 1987. This led to a law in 1988 that set up rules for Native American gaming and state governments. Now, both tribes run large casinos in the county.
The county's population grew very quickly starting in the 1970s. By 1990, over a million people lived here. At first, many people moved here to live and commute to jobs in Los Angeles or Orange County. But since the late 1990s, Riverside County has also become a place where new businesses, offices, and factories are built, creating many local jobs.
What is Riverside County like?
Riverside County is very large, covering about 7,206 square miles. It is the fourth-largest county in California. It is about 180 miles wide from east to west, which is roughly the size of the entire state of New Jersey! Driving from the county seat in Riverside to the town of Blythe near the Colorado River can take about three hours.
The county has different types of land. The western part is often called the Inland Empire. The eastern part is mostly Mojave Desert or Colorado Desert. There are also mountains like the Santa Rosa Mountains and areas around the Salton Sea.
Plants and Animals in Riverside County

Riverside County has many different kinds of plants and animals. You can find many desert plants, but there are also forests. The Blue oak tree, which is native to California, grows in Riverside County at the southern end of its natural range.
