Since California became a U.S. state in 1850, it has sent congressional delegations to the United States Senate and United States House of Representatives. Each state elects two senators to serve for six years, and members of the House to two-year terms.
These are tables of congressional delegations from California to the United States Senate and the United States House of Representatives.
Beginning in the 118th Congress, California sends 52 individuals to the United States House of Representatives, down from the previous 53 due to reapportionment following the 2020 census. This is the first time the number of Representatives from California will decline in American history.[1]
