Diamond Bar is a city located in Los Angeles County, California. As of the 2000 census, the city had a total population of 56,287. It is named after the "diamond over a bar" branding iron registered in 1918 by ranch owner Frederich E. Lewis.
Located at the junction of the Pomona and Orange Freeways, Diamond Bar is primarily a residential city with shopping centers interspersed within the city. The city features a public Los Angeles County golf course.
As with most Southern California cities, more modest housing is located closer to freeways and main roads, while upscale housing is located mostly in hilly terrain. The Country, a gated hillside enclave of 751 multi-million dollar estate residences, was developed in the 1970s.
Diamond Bar has the first hydrogen fueling station to be built in Southern California; near the South Coast Air Quality Management District (AQMD) building.
Diamond Bar is located at 34°0'6" North, 117°49'15" West (34.001652, -117.820761). The main road through town, Diamond Bar Boulevard, runs along the bottom of the valley that eventually becomes Brea Canyon, and development rises from the boulevard on both sides, winding back over and through the surrounding hills. The city is roughly between the ends of the Chino Fault and the Whittier Fault, both part of the larger Elsinore fault zone.
Positioned in the southeastern corner of the San Gabriel Valley and of Los Angeles County, Diamond Bar is approximately 29 miles east of downtown Los Angeles. Its closest San Gabriel Valley neighbors are Walnut, and Rowland Heights. The city is also adjacent to the Inland Empire region (Chino, Chino Hills, Pomona) on the east, and Orange County (Brea, La Habra) to the south.
According to the United States Census Bureau, the city has a total area of 38.2 km2 (14.8 mi2), with no significant bodies of water.
Similar to many San Gabriel Valley cities such as San Marino and Arcadia, Diamond Bar has experienced a remarkable growth in Asian-American population - especially Taiwanese, Korean Americans, and Indian Americans - since the 1980s. Attracted to the area's schools and the prestige of a Diamond Bar address, many affluent Asian-Americans commuting to areas such as Rowland Heights and Alhambra have moved here. In addition, some Asian-oriented businesses have since appeared in the city as well, albeit not on the massive scale like in Rowland Heights, Monterey Park, or Artesia. The Hsi Lai Temple, the largest Buddhist temple in the western hemisphere, is in nearby Hacienda Heights.
