California's 18th congressional district is a congressional district located in the U.S. state of California. The district is currently represented by . Since the 2022 election, the district is landlocked and includes all of San Benito County and parts of Santa Clara and Monterey counties, including Salinas, Hollister, Watsonville, Gilroy, Soledad, and downtown and eastern San Jose.[3]
Due to the presence of Silicon Valley, the district had a median household income of $149,375, the second highest of any congressional district in the country.[1] [4] After redistricting, the district picked up agricultural areas of Monterey County, and its median household income dropped substantially, to $90,456.
Following the 2020 census and the subsequent 2020 United States redistricting cycle, California lost a congressional district, leading to significant changes across California's districts. Most of the area previously part of the 18th district was split into the new 16th district and 19th district. The 18th district was moved to cover the Salinas Valley in Monterey County and the downtown and east side of San Jose. With the changes, the 18th became a Latino majority district.[5]
Following the 2010 census and the subsequent 2010 United States redistricting cycle, California's 18th congressional district was redrawn by the California Citizens Redistricting Commission. Cities and CDPs in the district include Palo Alto, Stanford, Los Altos, Woodside, Mountain View, Los Altos Hills, Campbell, Saratoga, Los Gatos, and Scotts Valley; most of Menlo Park and Redwood City; and part of San Jose.
Following the 2000 census and the subsequent 2000 United States redistricting cycle, California's congressional districts were redrawn by the California State Legislature. From 2003 to 2013, the district was located in the San Joaquin Valley. It included Merced County and portions of San Joaquin, Stanislaus, Madera, and Fresno counties. Cities in the district included Modesto, most of Stockton, Ceres, Atwater, Merced, and Los Banos.
