District profile

Before redistricting in 2022, the district straddled the gateway between the Inland Empire and the California desert, stretching from Yucaipa and Hemet in the west to the Twentynine Palms region and western Coachella Valley in the east. It now covers the western suburbs of Los Angeles and eastern part of Ventura County, including Calabasas, Malibu, the Conejo Valley, Moorpark, and Simi Valley.
