ZIP 78251 vs ZIP 78250

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