ZIP 78249 vs ZIP 78240

This side-by-side compares ZIP 78249 (San Antonio, TX) and ZIP 78240 (San Antonio, TX) using the same Census ACS 5-Year table fields for both — no averages swapped in, no national proxies. ZIP 78249 has a population of 49,951 at 1,296 people per square mile, while ZIP 78240 has 51,111 at 1,742 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 78249 reports a median household income of $80,565 against $63,351 in ZIP 78240, with per-capita income of $37,981 vs $39,127. The share of adults holding a bachelor's degree or higher is 52.0% in 78249 and 38.4% in 78240. Poverty rate reads 16.0% vs 15.6%, and unemployment 5.8% vs 3.9% — 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 $305,400 in 78249 versus $257,500 in 78240, with median rent of $1,527 and $1,342 per month respectively. Homeownership rate is 51.0% vs 34.4%. 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.
