Source:

Delhi, IA — Hopkinton, IA

This side-by-side compares ZIP 52223 (Delhi, IA) and ZIP 52237 (Hopkinton, IA) using the same Census ACS 5-Year table fields for both — no averages swapped in, no national proxies. ZIP 52223 has a population of 1,351 at 11 people per square mile, while ZIP 52237 has 1,522 at 7 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 52223 reports a median household income of $89,250 against $84,063 in ZIP 52237, with per-capita income of $58,079 vs $32,449. The share of adults holding a bachelor's degree or higher is 21.2% in 52223 and 17.4% in 52237. Poverty rate reads 5.5% vs 13.1%, and unemployment 0.1% vs 3.3% — 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 $204,000 in 52223 versus $166,800 in 52237, with median rent of $880 and $416 per month respectively. Homeownership rate is 88.5% vs 87.9%. 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.
