Data for ZIP Code Tabulation Area (ZCTA) 63303 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.
For this entity, the underlying data on this page comes from the U.S. Census Bureau ACS and decennial files. The breakdown above is the federal record; the paragraphs below add the per-entity context that makes the headline numbers usable for a real decision rather than just a data lookup.
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.
