ZIP 00917 vs ZIP 00918

This side-by-side compares ZIP 00917 (San Juan, PR) and ZIP 00918 (San Juan, PR) using the same Census ACS 5-Year table fields for both — no averages swapped in, no national proxies. ZIP 00917 has a population of 21,053 at 6,266 people per square mile, while ZIP 00918 has 18,056 at 3,273 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 00917 reports a median household income of $19,357 against $39,287 in ZIP 00918, with per-capita income of $17,172 vs $38,483. The share of adults holding a bachelor's degree or higher is 32.2% in 00917 and 60.8% in 00918. Poverty rate reads 51.6% vs 26.7%, and unemployment 19.5% vs 9.8% — 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 $121,600 in 00917 versus $230,900 in 00918, with median rent of $575 and $563 per month respectively. Homeownership rate is 45.5% vs 48.6%. 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.
