Gonzales, TX — Cost, TX

This side-by-side compares ZIP 78629 (Gonzales, TX) and ZIP 78614 (Cost, TX) using the same Census ACS 5-Year table fields for both — no averages swapped in, no national proxies. ZIP 78629 has a population of 11,887 at 11 people per square mile, while ZIP 78614 has 456 at 4 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 78629 reports a median household income of $59,521 against in ZIP 78614, with per-capita income of $27,422 vs $24,250. The share of adults holding a bachelor's degree or higher is 11.7% in 78629 and 26.0% in 78614. Poverty rate reads 18.1% vs 21.0%, and unemployment 4.5% vs 0.0% — these four fields alone drive most of the difference in the scorecard grades you will see for each ZIP.

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.
