A recent study published in January 2025 has revealed that California has more immigrants than any other state in the United States, and the numbers are staggering. The research by the PPIC, Public Policy Institute of California, was published in January 2025 and takes the latest data available on the population of this state.

The cities in California that host the most immigrants: which ones are

There are five cities in California that concentrate the majority of immigrants -according to the PPIC-. Residents born abroad represented at least a third of the population in Santa Clara, San Mateo, Alameda, San Francisco, and Los Angeles in 2023, the latest updated data available, according to researchers Marisol Cuellar Mejía, Cesar Alesi Pérez, and Hans Johnson.

The conclusion reached by this research is that the immigrant population in California is concentrated in the coastal metropolitan areas, mostly documented immigrants, and almost half of the children in this state have at least one parent born abroad.

These cities host the largest number of foreign-born individuals, and here is a fact: California is home to 10.6 million immigrants, representing 22% of the foreign-born population nationwide.

The following are the most relevant data from the study published by the PPIC.

-More than half (55%) of California's immigrants were naturalized U.S. citizens in 2023. This means that the majority of immigrants in California are documented residents.

-Residents born abroad represent a very small part of the population in most counties in the far north and the Sierra Nevada (in contrast to the far south of California).

-In 2023, the year with the most recent data, 27% of California's population was born abroad, the highest proportion of any state, and more than double the rest of the country (12%).

-Almost half (45%) of California's children have at least one immigrant parent.

-A third (34%) of working-age adults (25-54 years old) were born abroad; half (52%) of all Californians born abroad are in this age group.

According to data from the Pew Research Center, the number of undocumented individuals in California has decreased significantly over the past fifteen years. They estimate that in 2022, there were 1.8 million undocumented immigrants, much fewer than the 2.8 million in 2007, shrinking the proportion from 28% to 17%.
