ZIP 40121 vs ZIP 40155

This side-by-side compares ZIP 40121 (Fort Knox, KY) and ZIP 40155 (Muldraugh, KY) using the same Census ACS 5-Year table fields for both — no averages swapped in, no national proxies.

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 40121 reports a median household income of $82,663 against $60,508 in ZIP 40155, with per-capita income of $32,370 vs $36,939.

Poverty rate reads 9.0% vs 22.5%, and unemployment 5.3% vs 5.7% — 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.
