ZIP 78250 vs ZIP 78251

This side-by-side compares ZIP 78250 (San Antonio, TX) and ZIP 78251 (San Antonio, TX) using the same Census ACS 5-Year table fields for both — no averages swapped in, no national proxies. ZIP 78250 has a population of 54,903 at 2,207 people per square mile, while ZIP 78251 has 49,435 at 1,258 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 78250 reports a median household income of $80,659 against $78,958 in ZIP 78251, with per-capita income of $33,243 vs $37,549. The share of adults holding a bachelor's degree or higher is 32.2% in 78250 and 33.8% in 78251. Poverty rate reads 10.9% vs 8.7%, and unemployment 5.0% vs 7.5% — 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 $235,000 in 78250 versus $268,300 in 78251, with median rent of $1,530 and $1,413 per month respectively. Homeownership rate is 73.1% vs 50.8%. 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.
