ZIP 77551 vs ZIP 77550

This side-by-side compares ZIP 77551 (Galveston, TX) and ZIP 77550 (Galveston, TX) using the same Census ACS 5-Year table fields for both — no averages swapped in, no national proxies. ZIP 77551 has a population of 17,753 at 1,798 people per square mile, while ZIP 77550 has 23,043 at 1,185 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 77551 reports a median household income of $58,344 against $45,047 in ZIP 77550, with per-capita income of $38,601 vs $35,654. The share of adults holding a bachelor's degree or higher is 30.6% in 77551 and 34.5% in 77550. Poverty rate reads 18.4% vs 26.9%, and unemployment 4.5% vs 7.0% — 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 $290,600 in 77551 versus $325,900 in 77550, with median rent of $1,352 and $1,205 per month respectively. Homeownership rate is 48.2% vs 40.0%. 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.
