ZIP 50666 vs ZIP 50658

This side-by-side compares ZIP 50666 (Plainfield, IA) and ZIP 50658 (Nashua, IA) using the same Census ACS 5-Year table fields for both — no averages swapped in, no national proxies. ZIP 50666 has a population of 1,027 at 7 people per square mile, while ZIP 50658 has 2,518 at 14 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 50666 reports a median household income of $79,867 against $71,936 in ZIP 50658, with per-capita income of $38,596 vs $37,714. The share of adults holding a bachelor's degree or higher is 7.8% in 50666 and 15.7% in 50658. Poverty rate reads 4.2% vs 7.4%, and unemployment 3.8% vs 5.2% — 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 $203,700 in 50666 versus $155,100 in 50658, with median rent of $684 and $766 per month respectively. Homeownership rate is 94.7% vs 80.5%. 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.
