Alhambra, CA — Alhambra, CA

This side-by-side compares ZIP 91801 (Alhambra, CA) and ZIP 91803 (Alhambra, CA) using the same Census ACS 5-Year table fields for both — no averages swapped in, no national proxies. ZIP 91801 has a population of 52,735 at 4,672 people per square mile, while ZIP 91803 has 30,322 at 3,585 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 91801 reports a median household income of $89,156 against $84,311 in ZIP 91803, with per-capita income of $43,895 vs $42,858. The share of adults holding a bachelor's degree or higher is 42.0% in 91801 and 38.3% in 91803. Poverty rate reads 12.3% vs 13.3%, and unemployment 5.8% vs 4.0% — 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 $834,000 in 91801 versus $888,600 in 91803, with median rent of $1,981 and $1,847 per month respectively. Homeownership rate is 37.4% vs 48.4%. 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.
