Data for ZIP Code Tabulation Area (ZCTA) 91766 from the American Community Survey 5-Year estimates. ZCTAs approximately correspond to USPS ZIP code delivery areas but are built from Census blocks and may not match exactly.
The this entity record above pulls directly from the U.S. Census Bureau ACS and decennial files. What follows is the per-entity context — how this entity sits in the broader U.S. population demographics distribution and which underlying factors drive the headline numbers.
Every number on this page links back to the U.S. Census Bureau ACS and decennial files; the methodology page describes the inputs, refresh cadence, and known limitations of the underlying data product.
Practical use of this page is in combination with the comparison and ranking pages elsewhere on the site, which surface the same data for this entity’s peers within U.S. states, metros, cities, and ZIPs. A single-entity reading without peer context can be misleading when an entity is an outlier on one axis but typical on another.
