Malibu (/ˈmælɨbuː/) is an affluent beach city in Los Angeles County, California. As of the 2010 census, the city population was 12,645. Malibu consists of a 21-mile (34 km) strip of prime Pacific coastline. Nicknamed "the 'Bu" by surfers and locals, the community is famous for its warm, sandy beaches, and for being the home of many Hollywood movie stars and others associated with the entertainment industry. Signs around the city proclaim "27 miles of scenic beauty", referring to Malibu's original length of 27 miles (43 km) before the city was incorporated in 1991.
Most Malibu residents live within a few hundred yards of Pacific Coast Highway (State Route 1), which traverses the city, with some residents living up to a mile away from the beach up narrow canyons, and many more residents of the unincorporated canyon areas identifying Malibu as their hometown. The city is also bounded by Topanga to the east, the Santa Monica Mountains (Agoura Hills, Calabasas, and Woodland Hills) to the north, the Pacific Ocean to the south, and Ventura County to the west.
