ZIP 91786 vs ZIP 91784

This side-by-side compares ZIP 91786 (Upland, CA) and ZIP 91784 (Upland, CA) using the same Census ACS 5-Year table fields for both — no averages swapped in, no national proxies. ZIP 91786 has a population of 51,165 at 2,207 people per square mile, while ZIP 91784 has 25,938 at 1,099 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 91786 reports a median household income of $92,458 against $154,349 in ZIP 91784, with per-capita income of $42,150 vs $60,591. The share of adults holding a bachelor's degree or higher is 32.8% in 91786 and 46.8% in 91784. Poverty rate reads 10.5% vs 6.5%, and unemployment 5.3% vs 5.5% — 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 $641,600 in 91786 versus $891,600 in 91784, with median rent of $1,969 and $2,945 per month respectively. Homeownership rate is 45.9% vs 85.3%. 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.
