ZIP 01921 vs ZIP 01834

This side-by-side compares ZIP 01921 (Boxford, MA) and ZIP 01834 (Groveland, MA) using the same Census ACS 5-Year table fields for both — no averages swapped in, no national proxies. ZIP 01921 has a population of 7,961 at 131 people per square mile, while ZIP 01834 has 6,459 at 281 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 01921 reports a median household income of $200,672 against $141,487 in ZIP 01834, with per-capita income of $89,834 vs $61,949. The share of adults holding a bachelor's degree or higher is 70.6% in 01921 and 45.6% in 01834. Poverty rate reads 3.1% vs 3.2%, and unemployment 3.2% vs 5.0% — 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 $904,200 in 01921 versus $610,900 in 01834, with median rent of $776 and $1,825 per month respectively. Homeownership rate is 95.0% vs 90.3%. 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.
