ZIP 78233 vs ZIP 78239

This side-by-side compares ZIP 78233 (San Antonio, TX) and ZIP 78239 (San Antonio, TX) using the same Census ACS 5-Year table fields for both — no averages swapped in, no national proxies. ZIP 78233 has a population of 43,710 at 1,284 people per square mile, while ZIP 78239 has 28,736 at 1,671 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 78233 reports a median household income of $76,421 against $70,098 in ZIP 78239, with per-capita income of $34,614 vs $30,954. The share of adults holding a bachelor's degree or higher is 27.5% in 78233 and 27.8% in 78239. Poverty rate reads 10.4% vs 12.9%, and unemployment 4.3% vs 5.7% — 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 $220,800 in 78233 versus $229,200 in 78239, with median rent of $1,514 and $1,469 per month respectively. Homeownership rate is 60.4% vs 73.8%. 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.
