Definition: Estimated percentage of aggregate household income by quintile, by legislative district (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. 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.
