ZIP 78703 vs ZIP 78705

This side-by-side compares ZIP 78703 (Austin, TX) and ZIP 78705 (Austin, TX) using the same Census ACS 5-Year table fields for both — no averages swapped in, no national proxies. ZIP 78703 has a population of 19,690 at 1,366 people per square mile, while ZIP 78705 has 31,340 at 5,511 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 78703 reports a median household income of $153,036 against $32,380 in ZIP 78705, with per-capita income of $131,918 vs $26,154. The share of adults holding a bachelor's degree or higher is 86.0% in 78703 and 81.3% in 78705. Poverty rate reads 6.8% vs 47.2%, and unemployment 5.1% 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 $1,495,800 in 78703 versus $647,600 in 78705, with median rent of $2,181 and $1,571 per month respectively. Homeownership rate is 53.5% vs 13.1%. 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.
