Definition: Estimated percentage of the population born outside of the United States, by age group (e.g., in 2021, 5.4% of California children ages 5-17 were foreign-born).
Data Source: Population Reference Bureau, analysis of U.S. Census Bureau American Community Survey summary files and public use microdata (Mar. 2024).
Footnote: The foreign-born population includes naturalized U.S. citizens, lawful permanent residents, temporary migrants, humanitarian migrants, and unauthorized migrants. These estimates are based on a survey of the population and are subject to both sampling and nonsampling error. Data for 2020 are not available due to disruptions in data collection. The notation S refers to estimates that have been suppressed because the margin of error was greater than 5 percentage points. N/A means that data are not available.
