ZIP 91107 vs ZIP 91104

This side-by-side compares ZIP 91107 (Pasadena, CA) and ZIP 91104 (Pasadena, CA) using the same Census ACS 5-Year table fields for both — no averages swapped in, no national proxies. ZIP 91107 has a population of 32,940 at 1,546 people per square mile, while ZIP 91104 has 36,751 at 3,729 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 91107 reports a median household income of $126,449 against $105,958 in ZIP 91104, with per-capita income of $69,907 vs $53,241. The share of adults holding a bachelor's degree or higher is 61.0% in 91107 and 50.0% in 91104. Poverty rate reads 8.2% vs 12.6%, and unemployment 4.3% vs 4.8% — 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 $1,155,300 in 91107 versus $1,080,100 in 91104, with median rent of $2,413 and $2,063 per month respectively. Homeownership rate is 61.1% vs 55.4%. 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.
