ZIP 90620 vs ZIP 90621

This side-by-side compares ZIP 90620 (Buena Park, CA) and ZIP 90621 (Buena Park, CA) using the same Census ACS 5-Year table fields for both — no averages swapped in, no national proxies. ZIP 90620 has a population of 45,113 at 2,724 people per square mile, while ZIP 90621 has 35,153 at 3,272 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 90620 reports a median household income of $126,094 against $97,612 in ZIP 90621, with per-capita income of $43,056 vs $37,724. The share of adults holding a bachelor's degree or higher is 33.3% in 90620 and 32.7% in 90621. Poverty rate reads 7.7% vs 10.1%, and unemployment 4.8% vs 6.6% — 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 $840,300 in 90620 versus $832,000 in 90621, with median rent of $2,351 and $2,167 per month respectively. Homeownership rate is 72.3% vs 34.8%. 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.
