ZIP 03906 vs ZIP 04073

Source:

North Berwick, ME — Sanford, ME

This side-by-side compares ZIP 03906 (North Berwick, ME) and ZIP 04073 (Sanford, ME) using the same Census ACS 5-Year table fields for both — no averages swapped in, no national proxies. ZIP 03906 has a population of 4,647 at 47 people per square mile, while ZIP 04073 has 16,189 at 167 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 03906 reports a median household income of $105,156 against $72,917 in ZIP 04073, with per-capita income of $45,200 vs $38,244. The share of adults holding a bachelor's degree or higher is 29.4% in 03906 and 22.6% in 04073. Poverty rate reads 4.2% vs 8.8%, and unemployment 3.6% vs 4.1% — 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 $432,900 in 03906 versus $282,900 in 04073, with median rent of $1,105 and $1,151 per month respectively. Homeownership rate is 88.9% vs 69.4%. 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.
