ZIP 91790 vs ZIP 91791

This side-by-side compares ZIP 91790 (West Covina, CA) and ZIP 91791 (West Covina, CA) using the same Census ACS 5-Year table fields for both — no averages swapped in, no national proxies. ZIP 91790 has a population of 44,907 at 3,004 people per square mile, while ZIP 91791 has 32,414 at 1,886 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 91790 reports a median household income of $102,927 against $102,266 in ZIP 91791, with per-capita income of $37,383 vs $44,351. The share of adults holding a bachelor's degree or higher is 24.7% in 91790 and 33.4% in 91791. Poverty rate reads 9.6% vs 9.1%, and unemployment 6.2% vs 8.6% — 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 $770,900 in 91790 versus $843,600 in 91791, with median rent of $2,391 and $1,915 per month respectively. Homeownership rate is 61.4% vs 64.5%. 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.
