Population Non-Hispanic White % by Zip Code (ZCTA5) — Philadelphia Metro

NOTE: Gray indicates insufficient data or a suppressed estimate.

The Philadelphia metro area exhibits a pronounced urban-suburban racial divide, with zip codes in and around Center City Philadelphia, Camden, Chester, and Trenton displaying the lowest Non-Hispanic White population shares—often below 20%—while surrounding suburban and exurban areas, particularly to the northwest and southwest, frequently exceed 80%. A notable cluster of high-diversity zip codes extends north from Center City through North Philadelphia, contrasting sharply with the predominantly white outer-ring suburbs of Chester, Montgomery, and Bucks counties. Pockets of lower Non-Hispanic White percentages also appear near Norristown and along the Delaware River corridor on the New Jersey side, suggesting that racial demographic variation tracks closely with proximity to legacy industrial cities and their immediate surroundings.
