ZIP 91730 vs ZIP 91764

This side-by-side compares ZIP 91730 (Rancho Cucamonga, CA) and ZIP 91764 (Ontario, CA) using the same Census ACS 5-Year table fields for both — no averages swapped in, no national proxies. ZIP 91730 has a population of 66,925 at 1,784 people per square mile, while ZIP 91764 has 54,086 at 2,601 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 91730 reports a median household income of $92,237 against $81,762 in ZIP 91764, with per-capita income of $41,038 vs $28,059. The share of adults holding a bachelor's degree or higher is 32.6% in 91730 and 19.3% in 91764. Poverty rate reads 10.2% vs 16.7%, and unemployment 6.1% vs 6.4% — 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 $616,300 in 91730 versus $565,800 in 91764, with median rent of $2,299 and $2,181 per month respectively. Homeownership rate is 47.3% vs 45.1%. 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.
