- ZCTAs are Census statistical areas that approximate USPS ZIP code delivery areas; the code was matched to the ZCTA with the same code, which may not cover the same addresses as the ZIP code.
- Values are ACS 5-year estimates for 2020-2024 (dollars in 2024 dollars), not current figures.
- ZCTA-county overlaps come from the Census 2020 relationship file and use 2020 counties, by land area; Connecticut uses its legacy counties, not the planning regions in ACS 2022+.
