On 20 December 2021, the state redistricting commission unanimously approved a new map of congressional districts, under which the new District 16 overlaps largely with the old District 18.[3] The primary election of June 2022 was the first to feature the new districts; however, sitting representatives will reflect the old district boundaries until the general election in November 2022.

Prior to the 2020s redistricting, the district included Merced County, most of Madera County, and part of Fresno County. During this time, cities in the district included Los Banos, Madera, Merced, and most of Fresno. The new 16th district is in San Mateo County and Santa Clara County and includes Pacifica, Half Moon Bay, Atherton, Palo Alto, Saratoga, Campbell, Woodside and Los Gatos, and the south-central and southwestern parts of San Jose. Most of the old 16th district is now part of the 13th and 21st districts.[4]
