ZIP Code 60203

ZIP code 60203, on Chicago's far north side, ranks among the city's more affluent pockets, with a median household income of $170,224 and per-capita income of $68,647. Homes here carry a median value of $468,400, and the county-level effective property tax rate of 1.91% means owners face a substantial annual bill tied to that valuation. Add Chicago's 10.25% combined sales tax, and the overall cost of living runs high. Household earnings comfortably exceed national norms, yet the layered tax structure—property plus sales—claims a meaningful share of that prosperity.
