ZIP 90604 vs ZIP 90605

This side-by-side compares ZIP 90604 (Whittier, CA) and ZIP 90605 (Whittier, CA) using the same Census ACS 5-Year table fields for both — no averages swapped in, no national proxies. ZIP 90604 has a population of 39,407 at 3,571 people per square mile, while ZIP 90605 has 40,331 at 2,755 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 90604 reports a median household income of $105,074 against $99,635 in ZIP 90605, with per-capita income of $38,636 vs $34,318. The share of adults holding a bachelor's degree or higher is 24.4% in 90604 and 21.8% in 90605. Poverty rate reads 6.3% vs 11.8%, and unemployment 3.0% vs 5.6% — 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 $785,200 in 90604 versus $721,400 in 90605, with median rent of $1,904 and $1,897 per month respectively. Homeownership rate is 65.4% vs 65.9%. 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.
