ZIP 07981 vs ZIP 07927

This side-by-side compares ZIP 07981 (Whippany, NJ) and ZIP 07927 (Cedar Knolls, NJ) using the same Census ACS 5-Year table fields for both — no averages swapped in, no national proxies. ZIP 07981 has a population of 8,865 at 509 people per square mile, while ZIP 07927 has 3,403 at 681 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 07981 reports a median household income of $149,893 against $170,400 in ZIP 07927, with per-capita income of $75,777 vs $69,692. The share of adults holding a bachelor's degree or higher is 55.4% in 07981 and 54.9% in 07927. Poverty rate reads 3.8% vs 2.2%, and unemployment 3.6% vs 0.8% — 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 $614,100 in 07981 versus $646,700 in 07927, with median rent of $2,556 and $2,849 per month respectively. Homeownership rate is 87.4% vs 58.9%. 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.
