Definition: Estimated percentage of aggregate household income by quintile (e.g., in 2016-2020, households with incomes in the highest quintile (80th percentile and above) earned 52% of all household income in California).
Data Source: U.S. Census Bureau, American Community Survey (Aug. 2022).
Footnote: Lowest quintile households are the 20 percent of households with the lowest incomes, second quintile households are those with incomes between the 20th and 40th percentile, and so on. Data are displayed for geographies with populations of at least 10,000 based on 2020 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. 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.
