ZIP 00603 vs ZIP 00690

This side-by-side compares ZIP 00603 (Aguadilla, PR) and ZIP 00690 (San Antonio, PR) using the same Census ACS 5-Year table fields for both — no averages swapped in, no national proxies. ZIP 00603 has a population of 54,689 at 668 people per square mile, while ZIP 00690 has 6,255 at 858 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 00603 reports a median household income of $20,933 against $25,755 in ZIP 00690, with per-capita income of $15,651 vs $13,266. The share of adults holding a bachelor's degree or higher is 28.4% in 00603 and 25.3% in 00690. Poverty rate reads 44.4% vs 47.3%, and unemployment 15.3% vs 9.9% — 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 $152,900 in 00603 versus $139,600 in 00690, with median rent of $475 and $607 per month respectively. Homeownership rate is 57.3% vs 44.8%. 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.
