US Census Bureau American Community Survey (ACS) 5-Year estimates for a ZIP code: total population, median household income, median age, and total housing units. ZIP codes map to Census ZCTAs (Census-drawn approximations); some ZIPs (PO-box-only or very new) have no ZCTA match and return 404. Reflects a rolling 5-year survey window, not real-time.
