ZIP 00670 vs ZIP 00685

Source:

Las Marias, PR — San Sebastian, PR

This side-by-side compares ZIP 00670 (Las Marias, PR) and ZIP 00685 (San Sebastian, PR) using the same Census ACS 5-Year table fields for both — no averages swapped in, no national proxies. ZIP 00670 has a population of 9,807 at 83 people per square mile, while ZIP 00685 has 42,831 at 213 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 00670 reports a median household income of $16,367 against $20,310 in ZIP 00685, with per-capita income of $10,577 vs $12,313. The share of adults holding a bachelor's degree or higher is 14.5% in 00670 and 21.7% in 00685. Poverty rate reads 57.7% vs 49.3%, and unemployment 5.3% vs 13.4% — 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 $86,600 in 00670 versus $115,700 in 00685, with median rent of $416 and $502 per month respectively. Homeownership rate is 72.9% vs 73.8%. 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.
