ZIP 00646 vs ZIP 00951

This side-by-side compares ZIP 00646 (Dorado, PR) and ZIP 00951 (Toa Baja, PR) using the same Census ACS 5-Year table fields for both — no averages swapped in, no national proxies. ZIP 00646 has a population of 38,199 at 712 people per square mile, while ZIP 00951 has 35 at 33 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 00646 reports a median household income of $36,265 against $22,669 in ZIP 00951, with per-capita income of $28,560 vs $13,402. The share of adults holding a bachelor's degree or higher is 40.7% in 00646 and 18.6% in 00951. Poverty rate reads 27.5% vs 44.2%, and unemployment 11.1% vs 13.9% — 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 $169,500 in 00646 versus $80,000 in 00951, with median rent of $700 and $519 per month respectively. Homeownership rate is 78.7% vs 18.7%. 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.
