Value Notes
Estimates are not comparable to other geographic levels due to methodology differences that may exist between different data sources.
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.
In Vintage 2022, as a result of the formal request from the state, Connecticut transitioned from eight counties to nine planning regions. For more details,
please see the Vintage 2022 release notes available here: Release Notes.
The vintage year (e.g., V2022) refers to the final year of the series (2020 thru 2022). 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.
