Santa Clarita is the fourth largest city in Los Angeles County, California, and the 24th largest in the state of California. It is located about 35 miles northwest of downtown Los Angeles. Six Flags Magic Mountain amusement park and Stevenson Ranch are both commonly associated with Santa Clarita, but are located just outside the city limits. Santa Clarita was ranked by Money magazine in 2006 as 18th of the top 100 places to live.
Santa Clarita was incorporated in December 1987 as the union of four unincorporated communities, Canyon Country, Newhall, Saugus, and Valencia, most of which are situated on the land of the former Rancho San Francisco. The four communities retain separate identities, and it is common for residents to refer to a specific neighborhood when asked where they are from. Santa Clarita is bounded on the west by the Golden State Freeway (I-5). The Antelope Valley Freeway (SR-14) runs northeast-southwest through an irregular east border, and the Newhall Pass is the city's southernmost point.
