Housing % of Units Built Since 2010, by Zip Code (ZCTA5) — New Jersey

NOTE: Gray indicates insufficient data or a suppressed estimate.

Zip codes in the northeastern urban corridor—particularly around Hudson County and parts of Bergen and Essex counties—display a pronounced split, with several areas exceeding 20–30% new construction alongside adjacent zones near 0%, reflecting the uneven nature of urban redevelopment. Central New Jersey, especially portions of Middlesex and Monmouth counties, contains scattered pockets of moderate new construction (8–12%), while much of the southern half of the state trends toward lower percentages, with notable exceptions along the coast and in select communities near the Philadelphia suburbs. The highest concentration of recent building activity appears clustered near transit-oriented development hubs and waterfront areas in the northeast, contrasting sharply with the rural northwestern highlands and Pine Barrens interior, which remain largely unchanged.
