July 1, 2024 to July 1, 2025 Population Estimates STATE POPULATION INCREASES BY 19,200 IN FISCAL YEAR 2024-2025 FOR IMMEDIATE RELEASE: CONTACT: H.D. Palmer (916) 323-0648 December 19th, 2025 Walter Schwarm (916) 323-4086 SACRAMENTO—California’s population grew by about 19,200, or 0.05 percent, in the year ending July 1, 2025, reaching 39,529,000 people, according to new data released today by the California Department of Finance. The 0.05-percent increase marks the third year of population growth for the state following two years of consecutive declines during the pandemic and reflects the combination of several factors: - International immigration continued to rebound from pandemic lows, with the largest gain in fiscal year 2024 of 260,000 persons—the highest level since 2018. Net international migration increased in recent years due to the rebound in legal immigrants after the pandemic and the expansion of international humanitarian migration programs between 2021 and 2024. In 2025, most of the humanitarian migration programs were terminated. As a result, net international migration for 2024-25 declined to 126,000 persons—approximately half of the 2023-24 level. - Greater domestic in-migration and slowed domestic out-migration helped to bring net loss in domestic migration down to 140,000 persons in 2023-24 from nearly 250,000 persons in 2022-23. Net domestic migration from California became more negative in 2024-2025, increasing to a loss of 216,000 persons, which is consistent with levels in 2018 and 2019. - Natural increase—the net result of births minus deaths— contributes an increase of 108,300 persons in 2024-25 as births are stable and deaths have returned to the state’s pre-pandemic trend. For over 20 years, California has experienced negative net domestic migration, in which the number of people moving out of the state in a year exceeds the number moving in. Since 2016, with the exception of 2023-24, net domestic outmigration has exceeded net international migration, leaving natural increase as the only source of population growth. Natural increase is constrained by continuing fertility declines and increased deaths from an aging population. Net international migration to California reached 126,000 people in the year ending July 1,2025, a significant positive for overall population growth. However, negative net domestic migration still outweighed these gains, resulting in a net total migration loss of over 89,000 residents. With change in policy for international humanitarian migration and deaths returning to long-term trends, California is likely to experience slower growth over the coming several years. Other highlights of the July 1, 2025, county population report include: - California’s 58 counties range in size from Alpine County, with just over 1,150 residents, to Los Angeles County with 9.9 million residents. The population increased in 28 counties, with most growth in the Central Valley and the Inland Empire. Population gains largely reflect natural increase exceeding the losses in net migration. Only Placer, Yuba, and Glenn counties experienced positive population contributions from natural increase, net international migration, and net domestic migration. - The state’s ten largest counties remain Los Angeles, San Diego, Orange, Riverside, San Bernardino, Santa Clara, Alameda, Sacramento, Contra Costa, and Fresno, with each having more than one million residents. These ten counties represent 72 percent of California’s population. Seven of the ten counties with one million or more people have positive population growth, leaving Contra Costa, Los Angeles, and Orange as counties with population loss. - Los Angeles County’s population had the largest numeric decline of almost 28,500 persons in the fiscal year 2025. The decrease is driven by higher domestic migration due to impacts of wildfires, especially the Palisades and Eaton fires, and a significant decrease in net international migration. In January 2025, Los Angeles County experienced nine destructive wildfires out of 14 such wildfires in Southern California. - Population growth rates range from a high of 0.73 percent in Yuba County to a low of negative1.61 percent in Lassen County. The next fastest-growing counties in terms of percentage growth were Madera (0.66 percent), Sutter (0.62 percent), Merced (0.56 percent), Sacramento (0.55 percent), and Fresno (0.52 percent), all largely driven by intra-state moves, continuing a pre-pandemic trend. - Although natural increase was a main source of population growth in the state, 25 counties experienced natural decrease—more deaths than births. Among those counties only Napa and Plumas experienced overall growth thanks to positive net migration, especially net domestic migration. Background Information Population estimates produced by the California Department of Finance are mandated by the California Constitution and various codes. Estimates are used by state agencies, California counties, academic institutions, private research organizations, the media, and the public. Primary uses include budgeting, needs assessment, program planning and evaluation, distribution of state funds, and the calculation of rates (such as birth, death, and incarceration). The California Department of Finance estimates population each year based on changes in births, deaths, domestic migration, and international migration. Estimates are developed using aggregate data from a variety of sources, including birth and death counts provided by the Department of Public Health, driver's license data from the Department of Motor Vehicles, housing unit data from local governments, school enrollment data from the Department of Education, and federal income tax return data from the U.S. Internal Revenue Service. This particular series of estimates was unable to incorporate tax return data and Census Bureau county proportions due to the federal government shutdown which started on October 1 and ended on November 12. As a result, future revisions may be more significant than normal. These statistical reports of administrative records do not disclose any information about individuals. The July 2025 population estimates employ an improved method for estimating net international migration. The California Department of Finance has added a new administrative data component – asylum seekers and people who arrived in the United States on various temporary protected status programs between 2020 to 2024. The resulting net immigration estimates for the 2021-2024 period have increased by 321,000 relative to the previous estimates published in December 2024. As usual, we also updated prior years of the population estimates to reflect the changes in method of estimating international migration. In this release, revised data are for all years from 2020 to 2024. Due to this revision, population in the July 2023 and July 2024 estimates were also revised upward from the previous December 2024 publication. County ranking tables, maps, and the E-2 (California County Population Estimates and Components of Change by Year, July 1, 2020-2025) methodology and data tables are included. The E-2 and companion reports E-6 (Population Estimates and Components of Change by County, July 1, 2020-2025) and E-7 (California Population Estimates, with Components of Change and Crude Rates, July
