ZIP 06401 vs ZIP 06418

This side-by-side compares ZIP 06401 (Ansonia, CT) and ZIP 06418 (Derby, CT) using the same Census ACS 5-Year table fields for both — no averages swapped in, no national proxies. ZIP 06401 has a population of 19,237 at 1,237 people per square mile, while ZIP 06418 has 12,914 at 984 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 06401 reports a median household income of $86,178 against $78,542 in ZIP 06418, with per-capita income of $47,904 vs $46,718. The share of adults holding a bachelor's degree or higher is 22.3% in 06401 and 35.5% in 06418. Poverty rate reads 9.3% vs 11.0%, and unemployment 9.0% vs 5.7% — 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 $285,800 in 06401 versus $258,500 in 06418, with median rent of $1,476 and $1,452 per month respectively. Homeownership rate is 58.3% vs 61.6%. 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.
