Why there are no demographics for 91931

Although 91931 is a standard delivery ZIP, the American Community Survey reports no usable income or housing estimates for it. That usually means the ZIP covers a campus, military installation, hospital, business park or other area with few conventional households (population 749), so the medians are suppressed or undefined.
