Population Non-Hispanic Asian % by Zip Code (ZCTA5) — New Jersey

NOTE: Gray indicates insufficient data or a suppressed estimate.

The highest concentrations of Non-Hispanic Asian residents in New Jersey cluster prominently in central Middlesex County—particularly around Edison, Iselin, and South Brunswick—where several zip codes exceed 50%, along with pockets in Bergen County in the northeast. A secondary band of moderate Asian population shares (15–25%) extends through Morris, Somerset, and parts of Mercer counties, reflecting suburban communities with established South and East Asian populations. Southern New Jersey, from Burlington County through Cape May, remains predominantly below 2–5%, creating a stark north-south demographic divide across the state.
