Starting in the mid-1900s, there was a large growth in population in the East County, moving from the San Fernando Valley in Los Angeles and out into the Conejo and Simi Valleys. Part of the Conejo Valley belongs to Los Angeles County. This part consists of Calabasas, Hidden Hills, Agoura Hills, Agoura, and Westlake Village. The other half of the Conejo Valley, which belongs to Ventura County, consists of Lake Sherwood, Hidden Valley, Oak Park, Thousand Oaks, and Newbury Park, which was formerly an unincorporated area that is now the most westerly part of Thousand Oaks.
Parts of the county are on the Oxnard Plain which includes the cities of Oxnard, Camarillo, Port Hueneme and much of Ventura. Other cities and communities lie in the intermountain valleys of the Transverse Range. The Santa Clara River Valley is the most prominent valley, while other valleys include Conejo Valley, Simi Valley, Santa Rosa Valley, Tierra Rejada Valley and Las Posas Valley. Other parts of the county are on small coastal mountains, such as the Santa Ynez Mountains, Simi Hills, Santa Monica Mountains and the Piru Mountains. Most of the population of Ventura County lives in the southern portion of the county. The major population centers are the Oxnard Plain and the Simi and Conejo Valleys. In local media, the county is usually split between the eastern portion, generally associated with the San Fernando Valley, and the western portion, often referred to as “Oxnard-Ventura.”
