Connecticut / Zip Codes by Population

Connecticut Zip Codes by Population

Below are 278 Connecticut zip codes ranked 1 through 276 (there are some ties). The population data are from the 2020 American Community Survey. You can copy and paste this list directly into your favorite spreadsheet program. Don't you just adore lovely numbers listed nicely in columns & rows? We do!

Some of these zips may be mostly within a neighboring state and only slightly within Connecticut. We follow the US Census Bureau’s lead here and if any portion of the zip code intersects Connecticut (no matter how small), we include that zip code both in the Connecticut list below as well as in the neighboring state’s list of zip codes.
