ZIP 37066 vs ZIP 37048

This side-by-side compares ZIP 37066 (Gallatin, TN) and ZIP 37048 (Cottontown, TN) using the same Census ACS 5-Year table fields for both — no averages swapped in, no national proxies. ZIP 37066 has a population of 42,758 at 144 people per square mile, while ZIP 37048 has 6,030 at 53 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 37066 reports a median household income of $81,614 against $100,446 in ZIP 37048, with per-capita income of $46,209 vs $52,799. The share of adults holding a bachelor's degree or higher is 35.4% in 37066 and 29.0% in 37048. Poverty rate reads 12.1% vs 5.2%, and unemployment 2.9% vs 2.9% — these four fields alone drive most of the difference in the scorecard grades you will see for each ZIP.

Housing separates these two ZIPs further: median home value sits at $405,400 in 37066 versus $434,400 in 37048, with median rent of $1,391 and $1,148 per month respectively. Homeownership rate is 63.8% vs 88.1%. 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.
