Signal Mountain, TN — Chattanooga, TN

This side-by-side compares ZIP 37377 (Signal Mountain, TN) and ZIP 37415 (Chattanooga, TN) using the same Census ACS 5-Year table fields for both — no averages swapped in, no national proxies. ZIP 37377 has a population of 15,310 at 79 people per square mile, while ZIP 37415 has 23,873 at 507 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 37377 reports a median household income of $119,636 against $70,972 in ZIP 37415, with per-capita income of $68,322 vs $46,945. The share of adults holding a bachelor's degree or higher is 59.0% in 37377 and 44.9% in 37415. Poverty rate reads 5.2% vs 11.1%, and unemployment 2.8% vs 3.0% — 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 $529,500 in 37377 versus $285,000 in 37415, with median rent of $1,614 and $1,332 per month respectively. Homeownership rate is 85.9% vs 57.5%. 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.
