Chattanooga, TN — Chattanooga, TN
This side-by-side compares ZIP 37421 (Chattanooga, 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 37421 has a population of 46,228 at 587 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 37421 reports a median household income of $82,517 against $70,972 in ZIP 37415, with per-capita income of $47,620 vs $46,945. The share of adults holding a bachelor's degree or higher is 38.8% in 37421 and 44.9% in 37415. Poverty rate reads 10.9% vs 11.1%, and unemployment 3.5% 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 $333,700 in 37421 versus $285,000 in 37415, with median rent of $1,405 and $1,332 per month respectively. Homeownership rate is 60.2% 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.
