ZIP 78210 vs ZIP 78203

This side-by-side compares ZIP 78210 (San Antonio, TX) and ZIP 78203 (San Antonio, TX) using the same Census ACS 5-Year table fields for both — no averages swapped in, no national proxies. ZIP 78210 has a population of 36,865 at 1,914 people per square mile, while ZIP 78203 has 6,099 at 1,832 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 78210 reports a median household income of $55,028 against $35,536 in ZIP 78203, with per-capita income of $25,435 vs $18,976. The share of adults holding a bachelor's degree or higher is 16.9% in 78210 and 10.8% in 78203. Poverty rate reads 25.3% vs 39.1%, and unemployment 7.7% vs 6.2% — 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 $189,400 in 78210 versus $158,000 in 78203, with median rent of $1,159 and $1,051 per month respectively. Homeownership rate is 60.8% vs 45.1%. 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.
