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

NOTE: Gray indicates insufficient data or a suppressed estimate.

New construction activity concentrates most visibly in the suburban corridors surrounding Pittsburgh in the southwest and in the exurban ring of the Philadelphia metro area to the southeast, where several zip codes exceed 12–20% of housing stock built since 2010. The north-central and northeastern regions of the state are dominated by dark purple tones indicating minimal new construction, typically below 4%, reflecting the slower growth trajectories of rural and post-industrial communities. Scattered bright green and yellow outliers—likely tied to specific developments or smaller housing bases that amplify percentage figures—appear in the central-south corridor near Harrisburg and in pockets of the Lehigh Valley.
