ZIP 08542 vs ZIP 08540

This side-by-side compares ZIP 08542 (Princeton, NJ) and ZIP 08540 (Princeton, NJ) using the same Census ACS 5-Year table fields for both — no averages swapped in, no national proxies. ZIP 08542 has a population of 5,189 at 3,868 people per square mile, while ZIP 08540 has 47,115 at 350 per square mile. That difference in population size and density alone reshapes how every other metric should be interpreted — a higher-income ZIP with 1,200 residents behaves very differently from one with 45,000.

On income and education, ZIP 08542 reports a median household income of $105,524 against $176,983 in ZIP 08540, with per-capita income of $72,582 vs $89,601. The share of adults holding a bachelor's degree or higher is 70.7% in 08542 and 82.7% in 08540. Poverty rate reads 4.2% vs 8.2%, and unemployment 5.0% vs 4.1% — these four fields alone drive most of the difference in the scorecard grades you will see for each ZIP.

Housing separates these two ZIPs further: median home value sits at $754,100 in 08542 versus $767,900 in 08540, with median rent of $2,497 and $2,218 per month respectively. Homeownership rate is 32.3% vs 63.7%. When reading the comparison table below, focus on paired metrics rather than single winners — a ZIP with lower home values and lower income is not strictly "worse" if rent-to-income ratios and commute times land in the same zone. Every value is pulled from the exact same ACS table so the two columns are genuinely comparable.
