ZIP 91311 vs ZIP 91326

This side-by-side compares ZIP 91311 (Chatsworth, CA) and ZIP 91326 (Porter Ranch, CA) using the same Census ACS 5-Year table fields for both — no averages swapped in, no national proxies. ZIP 91311 has a population of 36,557 at 440 people per square mile, while ZIP 91326 has 33,708 at 1,595 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 91311 reports a median household income of $119,386 against $148,281 in ZIP 91326, with per-capita income of $53,824 vs $65,803. The share of adults holding a bachelor's degree or higher is 46.2% in 91311 and 59.2% in 91326. Poverty rate reads 8.8% vs 6.3%, and unemployment 5.4% 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 $876,400 in 91311 versus $1,106,000 in 91326, with median rent of $2,311 and $3,145 per month respectively. Homeownership rate is 66.6% vs 75.8%. 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.
