ZIP 01450 vs ZIP 01432

This side-by-side compares ZIP 01450 (Groton, MA) and ZIP 01432 (Ayer, MA) using the same Census ACS 5-Year table fields for both — no averages swapped in, no national proxies. ZIP 01450 has a population of 10,646 at 125 people per square mile, while ZIP 01432 has 7,089 at 323 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 01450 reports a median household income of $193,292 against $101,966 in ZIP 01432, with per-capita income of $80,105 vs $58,087. The share of adults holding a bachelor's degree or higher is 70.3% in 01450 and 41.9% in 01432. Poverty rate reads 3.9% vs 10.7%, and unemployment 5.4% vs 7.1% — 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 $743,400 in 01450 versus $463,800 in 01432, with median rent of $1,473 and $1,442 per month respectively. Homeownership rate is 89.0% vs 69.5%. 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.
