ZIP 37683 vs ZIP 37640

This side-by-side compares ZIP 37683 (Mountain City, TN) and ZIP 37640 (Butler, TN) using the same Census ACS 5-Year table fields for both — no averages swapped in, no national proxies. ZIP 37683 has a population of 13,021 at 37 people per square mile, while ZIP 37640 has 3,743 at 14 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 37683 reports a median household income of $55,979 against $55,402 in ZIP 37640, with per-capita income of $25,823 vs $36,615. The share of adults holding a bachelor's degree or higher is 14.7% in 37683 and 20.9% in 37640. Poverty rate reads 21.4% vs 21.1%, and unemployment 3.6% vs 3.6% — 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 $177,000 in 37683 versus $174,000 in 37640, with median rent of $671 and $687 per month respectively. Homeownership rate is 76.9% vs 85.8%. 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.
