ZIP 91791 vs ZIP 91723

This side-by-side compares ZIP 91791 (West Covina, CA) and ZIP 91723 (Covina, CA) using the same Census ACS 5-Year table fields for both — no averages swapped in, no national proxies. ZIP 91791 has a population of 32,414 at 1,886 people per square mile, while ZIP 91723 has 18,275 at 3,038 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 91791 reports a median household income of $102,266 against $94,167 in ZIP 91723, with per-capita income of $44,351 vs $38,910. The share of adults holding a bachelor's degree or higher is 33.4% in 91791 and 25.2% in 91723. Poverty rate reads 9.1% vs 8.5%, and unemployment 8.6% vs 8.3% — 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 $843,600 in 91791 versus $717,300 in 91723, with median rent of $1,915 and $1,801 per month respectively. Homeownership rate is 64.5% vs 43.9%. 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.
