Kirkwood, IL — Smithshire, IL

This side-by-side compares ZIP 61447 (Kirkwood, IL) and ZIP 61478 (Smithshire, IL) using the same Census ACS 5-Year table fields for both — no averages swapped in, no national proxies. ZIP 61447 has a population of 924 at 10 people per square mile, while ZIP 61478 has 290 at 3 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 61447 reports a median household income of $82,583 against $75,625 in ZIP 61478, with per-capita income of $34,315 vs $31,299.

Poverty rate reads 8.2% vs 18.1%, and unemployment 1.9% vs 0.0% — these four fields alone drive most of the difference in the scorecard grades you will see for each ZIP.

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.
