Wilmington, DE (ZIP 19803) sits in New Castle County within the Philadelphia-Camden-Wilmington metro area. The page draws on 2 federal data feeds retrieved Apr 27.

NCES lists 4 schools serving the area, 4 non-charter. 4 colleges and universities serve the area, with median in-state tuition of $13,920. IRS data shows average household income (AGI) of $148,177, well above the ~$45K national average per return. Average annual pay across local establishments runs $88,182 per worker (Census ZBP) — a high-wage local economy. Federal QCEW filings show 303,806 covered jobs in this ZIP's primary county — a major regional employment hub. Comenity Bank holds 64% of FDIC-reported deposits in this ZIP (2024) — a notably concentrated local banking market.
