California is facing a significant decline in its congressional representation, projected to lose four seats by the 2030 Census, due to slow population growth. This marks only the second time California has lost representation since it became a state. According to new data from the US Census Bureau, the state experienced a net loss of 229,077 people between July 2024 and July 2025, with the majority moving to neighboring states such as Texas, Nevada, Arizona, and Washington.
The slowdown in US population growth is attributed to a decline in net international migration, which dropped from 2.7 million to 1.3 million during this period. This decrease, combined with relatively stable birth rates and death rates, has resulted in a 0.5% growth rate for 2025 β the nation's slowest since the early stages of the COVID-19 pandemic.
The impact is being felt nationwide, with all four census regions experiencing slower population growth or accelerated decline. California's loss of representation will significantly affect its congressional delegation from 52 to 48 seats. This shift is largely due to California's historically high immigration rates, which have declined in recent years under President Trump's policies.
Texas and Florida are expected to gain four congressional seats each if the trends hold, while other states may also experience changes in their representation. The reapportionment process, triggered by the Census Bureau's estimates, will determine the new congressional map for each state, taking into account shifts in population size and demographics.
