Cedar Knolls, NJ — Whippany, NJ

This side-by-side compares ZIP 07927 (Cedar Knolls, NJ) and ZIP 07981 (Whippany, NJ) using the same Census ACS 5-Year table fields for both — no averages swapped in, no national proxies. ZIP 07927 has a population of 3,403 at 681 people per square mile, while ZIP 07981 has 8,865 at 509 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 07927 reports a median household income of $170,400 against $149,893 in ZIP 07981, with per-capita income of $69,692 vs $75,777. The share of adults holding a bachelor's degree or higher is 54.9% in 07927 and 55.4% in 07981. Poverty rate reads 2.2% vs 3.8%, and unemployment 0.8% vs 3.6% — these four fields alone drive most of the difference in the scorecard grades you will see for each ZIP.

Homeownership rate is 58.9% vs 87.4%. 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.
