Method: Residential ZIP codes (Census 2020 ZCTAs) with 1,000 or more people living in households (200 or more households, at most 5 people a household, so campuses, bases and prisons are left out) that have their own page; for income and home value, a figure whose 90% margin is at most 25% of it (a value at a Census cap counts); ties share a rank; the 50 states, D.C. and Puerto Rico. ZIP codes where most residents are students are labeled. Density is the ACS population divided by the ZCTA's land area.
