ZIP 78575 vs ZIP 78520

This side-by-side compares ZIP 78575 (Olmito, TX) and ZIP 78520 (Brownsville, TX) using the same Census ACS 5-Year table fields for both — no averages swapped in, no national proxies. ZIP 78575 has a population of 8,056 at 252 people per square mile, while ZIP 78520 has 59,408 at 628 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 78575 reports a median household income of $71,765 against $50,116 in ZIP 78520, with per-capita income of $39,404 vs $21,364. The share of adults holding a bachelor's degree or higher is 44.2% in 78575 and 23.9% in 78520. Poverty rate reads 22.2% vs 23.2%, and unemployment 3.7% vs 6.6% — 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 $249,500 in 78575 versus $146,000 in 78520, with median rent of $1,085 and $865 per month respectively. Homeownership rate is 56.0% vs 60.2%. 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.
