Orange County is a county in the U.S. state of California. Its population was 3,010,232, making it the third most populous county in California, behind Los Angeles County and San Diego County. Orange County is famous for its tourism as the home of attractions like Disneyland, Knott's Berry Farm, and several beaches along its more than 40 miles (64 km) of coastline. It is part of the Tech Coast.
It is mostly suburban except for some traditionally urban areas at the centers of the older cities of Anaheim, Fullerton, Huntington Beach, Orange, and Santa Ana. There are several edge city-style developments such as Irvine Business Center, Newport Center, and South Coast Metro. The city of Santa Ana serves as the county seat, Anaheim as its main tourist destination, and Irvine as its major business and financial hub. All of these three Orange County cities have populations exceeding 200,000. Thirty-four incorporated cities are located in Orange County; the newest is Aliso Viejo, which was incorporated in 2001.
