ZIP 57551 vs ZIP 57714

This side-by-side compares ZIP 57551 (Martin, SD) and ZIP 57714 (Allen, SD) using the same Census ACS 5-Year table fields for both — no averages swapped in, no national proxies. ZIP 57551 has a population of 2,279 at 1 people per square mile, while ZIP 57714 has 872 at 2 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 57551 reports a median household income of $70,096 against — in ZIP 57714, with per-capita income of $25,744 vs $6,785. The share of adults holding a bachelor's degree or higher is 25.6% in 57551 and 0.0% in 57714. Poverty rate reads 20.5% vs 44.2%, and unemployment 7.1% vs 23.3% — 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 $161,900 in 57551 versus $111,600 in 57714, with median rent of $613 and $621 per month respectively. Homeownership rate is 64.9% vs 32.4%. 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.
