ZIP 04073 vs ZIP 03906

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