Gallatin, MO — Altamont, MO

This side-by-side compares ZIP 64640 (Gallatin, MO) and ZIP 64620 (Altamont, MO) using the same Census ACS 5-Year table fields for both — no averages swapped in, no national proxies. ZIP 64640 has a population of 3,140 at 9 people per square mile, while ZIP 64620 has 466 at 10 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 64640 reports a median household income of $61,302 against $74,464 in ZIP 64620, with per-capita income of $30,933 vs $33,963.

Poverty rate reads 12.6% vs 6.1%, and unemployment 2.5% 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.
