Where does ZIP code income data come from?

From the US Census Bureau's American Community Survey 5-year estimates, published for ZIP Code Tabulation Areas (ZCTAs). ZCTAs are census-built approximations of USPS delivery ZIPs, so a handful of PO-box-only ZIPs have no data at all.

Why does a ZIP show a different income than its city?

City figures average every neighbourhood together. A single ZIP can sit far above or below that average, which is exactly why ZIP-level numbers are the useful ones for site selection, lending and moving decisions.
