ZIP 91773 vs ZIP 91740

This side-by-side compares ZIP 91773 (San Dimas, CA) and ZIP 91740 (Glendora, CA) using the same Census ACS 5-Year table fields for both — no averages swapped in, no national proxies. ZIP 91773 has a population of 33,119 at 894 people per square mile, while ZIP 91740 has 25,356 at 1,967 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 91773 reports a median household income of $105,338 against $99,083 in ZIP 91740, with per-capita income of $51,240 vs $39,724. The share of adults holding a bachelor's degree or higher is 40.4% in 91773 and 30.6% in 91740. Poverty rate reads 9.9% vs 10.5%, and unemployment 4.6% vs 5.3% — 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 $800,700 in 91773 versus $787,400 in 91740, with median rent of $2,278 and $2,251 per month respectively. Homeownership rate is 72.3% vs 64.0%. 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.
