Source:

Olds, IA — Crawfordsville, IA

This side-by-side compares ZIP 52647 (Olds, IA) and ZIP 52621 (Crawfordsville, IA) using the same Census ACS 5-Year table fields for both — no averages swapped in, no national proxies. ZIP 52647 has a population of 229 at 251 people per square mile, while ZIP 52621 has 668 at 6 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 52647 reports a median household income of $49,375 against $87,188 in ZIP 52621, with per-capita income of $41,225 vs $37,779. The share of adults holding a bachelor's degree or higher is 10.6% in 52647 and 28.6% in 52621. Poverty rate reads 9.7% vs 5.5%, and unemployment 0.0% vs 2.2% — these four fields alone drive most of the difference in the scorecard grades you will see for each ZIP.

Homeownership rate is 46.5% vs 81.3%. 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.
