ZIP 51575 vs ZIP 51571

This side-by-side compares ZIP 51575 (Treynor, IA) and ZIP 51571 (Silver City, IA) using the same Census ACS 5-Year table fields for both — no averages swapped in, no national proxies. ZIP 51575 has a population of 1,616 at 13 people per square mile, while ZIP 51571 has 649 at 5 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 51575 reports a median household income of $112,115 against $95,250 in ZIP 51571, with per-capita income of $48,095 vs $41,199. The share of adults holding a bachelor's degree or higher is 41.4% in 51575 and 30.4% in 51571. Poverty rate reads 3.6% vs 11.1%, and unemployment 3.6% vs 2.7% — 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 $304,500 in 51575 versus $221,400 in 51571, with median rent of $1,133 and $1,130 per month respectively. Homeownership rate is 84.7% vs 82.7%. 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.
