ZIP 91342 vs ZIP 91340

This side-by-side compares ZIP 91342 (Sylmar, CA) and ZIP 91340 (San Fernando, CA) using the same Census ACS 5-Year table fields for both — no averages swapped in, no national proxies. ZIP 91342 has a population of 91,725 at 643 people per square mile, while ZIP 91340 has 34,188 at 3,904 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 91342 reports a median household income of $98,118 against $85,261 in ZIP 91340, with per-capita income of $32,744 vs $30,045. The share of adults holding a bachelor's degree or higher is 20.8% in 91342 and 13.6% in 91340. Poverty rate reads 12.0% vs 10.9%, and unemployment 7.5% vs 6.9% — 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 $695,600 in 91342 versus $661,500 in 91340, with median rent of $1,963 and $1,813 per month respectively. Homeownership rate is 67.8% vs 64.5%. 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.
