ZIP 37656 vs ZIP 37681

This side-by-side compares ZIP 37656 (Fall Branch, TN) and ZIP 37681 (Limestone, TN) using the same Census ACS 5-Year table fields for both — no averages swapped in, no national proxies. ZIP 37656 has a population of 3,677 at 46 people per square mile, while ZIP 37681 has 6,121 at 35 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 37656 reports a median household income of $63,617 against $65,857 in ZIP 37681, with per-capita income of $32,397 vs $37,405. The share of adults holding a bachelor's degree or higher is 22.4% in 37656 and 14.7% in 37681. Poverty rate reads 12.0% vs 15.3%, and unemployment 6.5% vs 1.2% — 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 $236,600 in 37656 versus $177,300 in 37681, with median rent of $794 and $767 per month respectively. Homeownership rate is 87.3% vs 87.2%. 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.
