ZIP 78255 vs ZIP 78256

This side-by-side compares ZIP 78255 (San Antonio, TX) and ZIP 78256 (San Antonio, TX) using the same Census ACS 5-Year table fields for both — no averages swapped in, no national proxies. ZIP 78255 has a population of 10,826 at 229 people per square mile, while ZIP 78256 has 6,855 at 305 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 78255 reports a median household income of $157,428 against $74,977 in ZIP 78256, with per-capita income of $71,506 vs $62,937. The share of adults holding a bachelor's degree or higher is 63.2% in 78255 and 55.9% in 78256. Poverty rate reads 5.9% vs 19.1%, and unemployment 4.2% vs 3.4% — 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 $531,400 in 78255 versus $579,300 in 78256, with median rent of $1,815 and $1,600 per month respectively. Homeownership rate is 84.8% vs 29.5%. 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.
