ZIP 37309 vs ZIP 37310

This side-by-side compares ZIP 37309 (Calhoun, TN) and ZIP 37310 (Charleston, TN) using the same Census ACS 5-Year table fields for both — no averages swapped in, no national proxies. ZIP 37309 has a population of 2,138 at 22 people per square mile, while ZIP 37310 has 4,135 at 38 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 37309 reports a median household income of $63,699 against $81,645 in ZIP 37310, with per-capita income of $27,879 vs $37,262. The share of adults holding a bachelor's degree or higher is 15.1% in 37309 and 11.3% in 37310. Poverty rate reads 11.5% vs 11.2%, and unemployment 8.7% vs 2.0% — 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 $172,600 in 37309 versus $270,600 in 37310, with median rent of $902 and $933 per month respectively. Homeownership rate is 80.9% vs 83.0%. 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.
