An analysis of census data released by Pew Research Center on Thursday noted that between January and June, the United States' foreign-born population had declined by more than a million people. Millions of people arrived at the border between 2021 and 2023 seeking refuge in America after the COVID-19 pandemic emergency, which ravaged many of their home countries. In 2023, California was home to 11.3 million immigrants, roughly 28.4% of the national total, according to Pew.
