Definition: Estimated percentage of the population born outside of the United States, by age group and legislative district (e.g., in 2016-2020, 5.6% of California children ages 5-17 were foreign-born).
Data Source: U.S. Census Bureau, American Community Survey (Aug. 2022).
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. Because of disruptions to data collection in 2020, American Community Survey estimates for 2016-2020 did not meet statistical quality requirements and have larger than usual margins of error; see Information and Advice on 2020 Federal Data Quality and Use.
