Delaware / Zip Codes by Population

Delaware Zip Codes by Population

Below are 66 Delaware zip codes sorted by population from largest to smallest. The population data are from the 2021 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 Delaware. We follow the US Census Bureau's lead here and if any portion of the zip code intersects Delaware (no matter how small), we include that zip code both in the Delaware list below as well as in the neighboring state's list of zip codes.
