Definition: Estimated population ages 0-17 (e.g., an estimated 9,140,283 children lived in California in 2012-2016).
Data Source: U.S. Census Bureau, American Community Survey (Jan. 2018).
Footnote: Data are displayed for geographies with at least 10,000 residents based on 2016 population estimates. These estimates are based on a survey of the population and are subject to both sampling and nonsampling error. 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. Some regions listed are Census Designated Places (CDPs), such as East Los Angeles; CDPs are communities within the unincorporated part of a county. In 2010 the Census Bureau implemented new population benchmarks, so caution should be taken when comparing 2005-2009 data with later years.
