El Cajon, CA — El Cajon, CA

This side-by-side compares ZIP 92021 (El Cajon, CA) and ZIP 92020 (El Cajon, CA) using the same Census ACS 5-Year table fields for both — no averages swapped in, no national proxies. ZIP 92021 has a population of 65,068 at 845 people per square mile, while ZIP 92020 has 57,767 at 2,002 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 92021 reports a median household income of $74,013 against $76,032 in ZIP 92020, with per-capita income of $35,192 vs $36,450. The share of adults holding a bachelor's degree or higher is 22.4% in 92021 and 27.0% in 92020. Poverty rate reads 18.5% vs 15.8%, and unemployment 8.0% vs 8.8% — 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 $611,900 in 92021 versus $813,100 in 92020, with median rent of $1,893 and $1,865 per month respectively. Homeownership rate is 53.8% vs 44.4%. 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.
