Value Notes
Methodology differences may exist between data sources, and so estimates from different sources are not comparable.
Some estimates presented here come from sample data, and thus have sampling errors that may render some apparent differences between geographies statistically
indistinguishable. Click the Quick Info icon to the left of each row in TABLE view to learn about sampling error.
The vintage year (e.g., V2023) refers to the final year of the series (2020 thru 2023). Different vintage years of estimates are not comparable.
Users should exercise caution when comparing 2018-2022 ACS 5-year estimates to other ACS estimates. For more information, please visit
the 2022 5-year ACS Comparison Guidance page.
