ZIP 01845 vs ZIP 01921

This side-by-side compares ZIP 01845 (North Andover, MA) and ZIP 01921 (Boxford, MA) using the same Census ACS 5-Year table fields for both — no averages swapped in, no national proxies. ZIP 01845 has a population of 28,352 at 417 people per square mile, while ZIP 01921 has 7,961 at 131 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 01845 reports a median household income of $140,670 against $200,672 in ZIP 01921, with per-capita income of $64,833 vs $89,834. The share of adults holding a bachelor's degree or higher is 61.1% in 01845 and 70.6% in 01921. Poverty rate reads 9.4% vs 3.1%, and unemployment 3.5% vs 3.2% — 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 $732,900 in 01845 versus $904,200 in 01921, with median rent of $2,223 and $776 per month respectively. Homeownership rate is 69.8% vs 95.0%. 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.
