Household Median Income by Zip Code (ZCTA5) — Maryland

NOTE: Gray indicates insufficient data or a suppressed estimate.

The central Maryland corridor spanning Montgomery, Howard, and portions of Anne Arundel and Prince George's counties forms a dominant high-income cluster, with numerous zip codes exceeding $125,000 in household median income. The Eastern Shore and Southern Maryland's lower peninsula display markedly lower median incomes, generally falling in the $40,000–$60,000 range, while the westernmost panhandle of Garrett and Allegany counties similarly trends toward lower income levels. A sharp contrast is visible within the Baltimore metropolitan area, where affluent suburban zip codes in Baltimore County sit adjacent to significantly lower-income zip codes in Baltimore City proper.
