- California’s population stalled near 39.5 million as international migration fell by over 50% in 2025.
- New DHS directives ended broad humanitarian parole and widened enforcement discretion across the state.
- Stricter asylum rules require applicants to submit all evidence within a new 14-day filing deadline.
(CALIFORNIA) — California’s population held near 39.5 million as federal immigration changes cut the flow of newcomers who had long helped offset residents leaving the state, according to figures from the California Department of Finance, the U.S. Census Bureau and the Department of Homeland Security.
The California Department of Finance put the state’s population at 39,529,000 as of July 1, 2025. Between January 2025 and January 2026, the state lost about 54,000 residents, leaving the total just under 39.6 million.
Net international migration to California dropped by more than half in the same period, falling from 248,400 in 2024 to 126,400 in 2025. State finance officials identify that decline as the main reason population growth stalled after signs of recovery in 2024.
Department of Homeland Security actions in the first days of President Trump’s new term reshaped the enforcement system that drives much of that migration. On January 21, 2025, DHS announced directives that widened enforcement discretion and ended broad humanitarian parole programs.
A DHS spokesperson said that day, “This action empowers the brave men and women in CBP and ICE to enforce our immigration laws and catch criminal aliens—including murderers and rapists—who have illegally come into our country. Criminals will no longer be able to hide in America’s schools and churches to avoid arrest. The Trump Administration will not tie the hands of our brave law enforcement, and instead trusts them to use common sense.”
On the same day, the administration also ended broad parole programs. A DHS spokesperson said, “The Biden-Harris Administration abused the humanitarian parole program to indiscriminately allow 1.5 million migrants to enter our country. This was all stopped on day one of the Trump Administration. This action will return the humanitarian parole program to its original purpose of looking at migrants on a case-by-case basis.”
A memo signed January 20, 2025 rescinded the 2021 Protected Areas policy, which had limited immigration enforcement in places such as schools, hospitals and houses of worship. The memo said, “It is not necessary. for the head of the agency to create bright line rules regarding where our immigration laws are permitted to be enforced. law enforcement officers should continue to use [enforcement] discretion along with a healthy dose of common sense.”
Those policy shifts were followed by new restrictions in asylum and visa processing during late 2025 and early 2026. USCIS paused affirmative asylum processing in late 2025, and a rule that took effect on March 30, 2026 now requires applicants to submit all supporting evidence within 14 days of filing.
Another change arrived on January 14, 2026, when the Department of State announced an “Immigrant Visa Processing Pause” for nationals of 75 countries deemed “at high risk of public benefits usage.” That pause took effect on January 21, 2026.
California’s demographic balance has long depended on arrivals from abroad making up for domestic out-migration. With that buffer weakened, pressure is building in sectors that rely on a steady inflow of workers, including tech, agriculture and services.
State officials warn that the loss of what they describe as a fresh supply of workers threatens the labor force. The effect reaches beyond payroll counts, touching local housing demand, school enrollment and consumer spending in communities that had depended on new arrivals to hold population steady.
The rescission of the Protected Areas policy has also deepened anxiety in immigrant communities. Enforcement is no longer strictly barred near schools, hospitals or places of worship, a change that carries practical weight even before any arrest takes place because people adjust routines around perceived risk.
Asylum seekers face another layer of pressure from the new filing rules and costs. The 14-day evidence deadline and the $102 annual asylum fee introduced in early 2026 now apply during a period when hundreds of thousands of cases sit on indefinite hold because of the USCIS slowdown.
That combination leaves less room for delay in assembling records that often take weeks to collect from abroad, including identity documents, police records and medical evidence. Missing the new deadline can turn a filing problem into a case problem quickly, particularly for applicants without lawyers or stable housing.
The U.S. Census Bureau has also tracked slower national population growth, but California’s numbers stand out because migration has historically done more of the work in sustaining the state’s total. A drop of more than 50% in net international migration in a single year changes that equation fast.
California remains the nation’s most populous state, yet the recent figures show how narrow the margin has become between growth and decline. A reduction of roughly 54,000 residents over a year is modest in a state of nearly 40 million, but it marks a reversal at a time when officials had been watching for a broader rebound.
Public records tied to the population shift are spread across several agencies. Demographic estimates are available from the California Department of Finance, national population data from the U.S. Census Bureau press release CB26-20, and federal policy announcements through the Department of Homeland Security newsroom and the USCIS newsroom.
Taken together, those records show a state still near 39.5 million, but with far less demographic momentum than a year earlier. In California, where international migration has often made the difference between growth and shrinkage, federal immigration policy now sits directly inside the population count.
