Anaheim  is a city in Orange County, California, part of the Los Angeles metropolitan area. As of the 2010 United States Census, the city had a population of 336,265, making it the most populous city in Orange County and the 10th-most populous city in California. Anaheim is the second-largest city in Orange County in terms of land area (after Irvine) and is known for its theme parks, the Anaheim Convention Center, and its two major sports teams: the Anaheim Ducks ice hockey club and the Angels baseball team. Anaheim was founded by fifty German families in 1857 and incorporated as the second city in Los Angeles County on March 18, 1876; Orange County would later be split off from Los Angeles County in 1889. Anaheim remained largely a rural community until Disneyland opened in the city in 1955. This led to the construction of several hotels and motels around the area, and residential districts in Anaheim soon followed. The city also developed into an industrial center, producing electronics, aircraft parts and canned fruit. Anaheim is a charter city. Anaheim's city limits extend from Cypress in the west to the Riverside County line in the east and encompass a diverse collection of neighborhoods and communities. Anaheim Hills is a master-planned community located in the city's eastern stretches that is home to many of the city's affluent. Downtown Anaheim has three mixed-use historic districts, the largest of which is the Anaheim Colony. The Anaheim Resort, a commercial district, includes the Disneyland Resort, with its two theme parks, multiple hotels, and retail district, and numerous hotels and retail complexes. The Platinum Triangle, a neo-urban redevelopment district surrounding Angel Stadium, is planned to be populated with mixed-use streets and high-rises. Anaheim Canyon is an industrial district north of California State Route 91 and east of California State Route 57.
