ZIP 91104 vs ZIP 91106

This side-by-side compares ZIP 91104 (Pasadena, CA) and ZIP 91106 (Pasadena, CA) using the same Census ACS 5-Year table fields for both — no averages swapped in, no national proxies. ZIP 91104 has a population of 36,751 at 3,729 people per square mile, while ZIP 91106 has 24,229 at 3,176 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 91104 reports a median household income of $105,958 against $90,028 in ZIP 91106, with per-capita income of $53,241 vs $70,310. The share of adults holding a bachelor's degree or higher is 50.0% in 91104 and 61.6% in 91106. Poverty rate reads 12.6% vs 11.8%, and unemployment 4.8% vs 6.4% — 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 $1,080,100 in 91104 versus $1,040,400 in 91106, with median rent of $2,063 and $2,177 per month respectively. Homeownership rate is 55.4% vs 35.9%. 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.
