ZIP 00909 vs ZIP 00912

This side-by-side compares ZIP 00909 (San Juan, PR) and ZIP 00912 (San Juan, PR) using the same Census ACS 5-Year table fields for both — no averages swapped in, no national proxies. ZIP 00909 has a population of 6,230 at 3,941 people per square mile, while ZIP 00912 has 6,801 at 7,881 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 00909 reports a median household income of $23,101 against $31,636 in ZIP 00912, with per-capita income of $26,593 vs $28,398. The share of adults holding a bachelor's degree or higher is 42.4% in 00909 and 41.9% in 00912. Poverty rate reads 42.6% vs 31.8%, and unemployment 9.9% vs 7.2% — 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 $174,300 in 00909 versus $145,900 in 00912, with median rent of $757 and $780 per month respectively. Homeownership rate is 40.8% vs 54.1%. 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.
