ZIP 06437 vs ZIP 06443

This side-by-side compares ZIP 06437 (Guilford, CT) and ZIP 06443 (Madison, CT) using the same Census ACS 5-Year table fields for both — no averages swapped in, no national proxies. ZIP 06437 has a population of 22,375 at 184 people per square mile, while ZIP 06443 has 18,269 at 195 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 06437 reports a median household income of $137,615 against $168,462 in ZIP 06443, with per-capita income of $73,108 vs $86,173. The share of adults holding a bachelor's degree or higher is 60.5% in 06437 and 72.5% in 06443. Poverty rate reads 2.8% vs 3.6%, and unemployment 4.9% vs 5.3% — 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 $515,000 in 06437 versus $584,900 in 06443, with median rent of $1,717 and $2,025 per month respectively. Homeownership rate is 83.6% vs 90.4%. 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.
