ZIP 02648 vs ZIP 02655

This side-by-side compares ZIP 02648 (Marstons Mills, MA) and ZIP 02655 (Osterville, MA) using the same Census ACS 5-Year table fields for both — no averages swapped in, no national proxies. ZIP 02648 has a population of 7,301 at 304 people per square mile, while ZIP 02655 has 3,518 at 208 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 02648 reports a median household income of $129,681 against $118,750 in ZIP 02655, with per-capita income of $53,565 vs $101,734. The share of adults holding a bachelor's degree or higher is 40.8% in 02648 and 60.7% in 02655. Poverty rate reads 3.0% vs 5.1%, and unemployment 2.9% vs 1.6% — 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 $593,600 in 02648 versus $806,300 in 02655, with median rent of $2,184 and $1,869 per month respectively. Homeownership rate is 97.5% vs 92.8%. 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.
