ZIP 02339 vs ZIP 02370

This side-by-side compares ZIP 02339 (Hanover, MA) and ZIP 02370 (Rockland, MA) using the same Census ACS 5-Year table fields for both — no averages swapped in, no national proxies. ZIP 02339 has a population of 13,879 at 345 people per square mile, while ZIP 02370 has 17,489 at 655 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 02339 reports a median household income of $189,803 against $112,405 in ZIP 02370, with per-capita income of $74,076 vs $51,822. The share of adults holding a bachelor's degree or higher is 56.8% in 02339 and 32.7% in 02370. Poverty rate reads 4.8% vs 6.5%, and unemployment 6.5% vs 4.4% — 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 $755,400 in 02339 versus $472,900 in 02370, with median rent of $1,845 and $1,610 per month respectively. Homeownership rate is 84.5% vs 76.5%. 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.
