Figures are U.S. Census Bureau ACS 5-year estimates, 2020-2024 for the ZIP Code Tabulation Area (ZCTA), the Census Bureau's stand-in for a ZIP code. They describe the area over the five-year survey window, not a single year, and small areas carry wider margins of error. Comparisons and ranks are computed on this site from the same figures; the "Los Angeles ZIP median" is the middle value across the Los Angeles ZIP codes here, each counted once.
