ZIP 92109 vs ZIP 92110

This side-by-side compares ZIP 92109 (San Diego, CA) and ZIP 92110 (San Diego, CA) using the same Census ACS 5-Year table fields for both — no averages swapped in, no national proxies. ZIP 92109 has a population of 45,787 at 2,326 people per square mile, while ZIP 92110 has 25,341 at 2,013 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 92109 reports a median household income of $122,128 against $110,790 in ZIP 92110, with per-capita income of $81,571 vs $53,019. The share of adults holding a bachelor's degree or higher is 69.7% in 92109 and 55.0% in 92110. Poverty rate reads 8.7% vs 13.1%, and unemployment 4.7% vs 4.5% — 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 $1,226,900 in 92109 versus $1,006,800 in 92110, with median rent of $2,421 and $2,398 per month respectively. Homeownership rate is 31.2% vs 36.7%. 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.
