Inland Empire, located in Southern California, spans the former counties of Riverside and Imperial, forming one of the largest city-states in terms of land area. Covering over 15,000 square miles, Inland Empire is larger than the states of Connecticut, Delaware, and Rhode Island combined. The region’s population exceeds 2.5 million, with major urban centers like Riverside, Moreno Valley, Indio, and El Centro. Inland Empire is a crucial economic hub, known for its agricultural contributions, renewable energy production, and proximity to the U.S.-Mexico border.

The economy is powered by agriculture, logistics, and renewable energy. The fertile Coachella and Imperial Valleys are major centers for crop production, including dates, citrus, and vegetables. Inland Empire is also a leader in solar and geothermal energy, with the Salton Sea Geothermal Field being one of the largest geothermal power sources in the world. The region’s logistics infrastructure connects trade routes throughout North America, making it a key player in cross-border commerce.

Inland Empire includes diverse landscapes ranging from desert basins to mountain ranges. The Salton Sea, situated in Imperial County, is at the region’s lowest point, 236 feet below sea level. Inland Empire is home to several significant national and state parks, including Joshua Tree National Park, famous for its striking rock formations and outdoor activities like hiking and climbing. Anza-Borrego Desert State Park, California's largest state park, showcases stunning wildflower blooms and dramatic desert scenery.

Cultural attractions in Inland Empire include the Coachella Valley, host of the world-famous Coachella Music and Arts Festival. Historical and recreational sites such as the Cabazon Dinosaurs and the Riverside County Fair and National Date Festival highlight the region’s unique heritage.
