ZIP 91789 vs ZIP 91792

This side-by-side compares ZIP 91789 (Walnut, CA) and ZIP 91792 (West Covina, CA) using the same Census ACS 5-Year table fields for both — no averages swapped in, no national proxies. ZIP 91789 has a population of 43,079 at 1,064 people per square mile, while ZIP 91792 has 30,854 at 3,101 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 91789 reports a median household income of $125,720 against $94,817 in ZIP 91792, with per-capita income of $49,392 vs $36,550. The share of adults holding a bachelor's degree or higher is 54.4% in 91789 and 34.2% in 91792. Poverty rate reads 9.2% vs 11.8%, and unemployment 4.4% vs 4.6% — 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 $975,000 in 91789 versus $696,200 in 91792, with median rent of $2,865 and $2,270 per month respectively. Homeownership rate is 82.1% vs 55.3%. 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.
