Radcliff, KY — Fort Knox, KY

This side-by-side compares ZIP 40160 (Radcliff, KY) and ZIP 40121 (Fort Knox, KY) using the same Census ACS 5-Year table fields for both — no averages swapped in, no national proxies. ZIP 40160 has a population of 23,574 at 540 people per square mile, while ZIP 40121 has 10,124 at 115 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 40160 reports a median household income of $58,506 against $82,663 in ZIP 40121, with per-capita income of $31,233 vs $32,370. The share of adults holding a bachelor's degree or higher is 16.3% in 40160 and 48.3% in 40121. Poverty rate reads 16.2% vs 9.0%, and unemployment 10.8% vs 5.3% — 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.
