this entity is one of the data points covered by this site’s U.S. population demographics dataset. The detail above comes directly from the U.S. Census Bureau ACS and decennial files; the context that follows situates the headline numbers against the broader distribution across U.S. states, metros, cities, and ZIPs.
The methodology behind every numeric value on this page is publicly documented on the the U.S. Census Bureau ACS and decennial files portal and described in detail on this site’s methodology page. Refresh cadence varies by underlying series; the page surfaces the as-of date for each number so readers can trace any figure back to the source release.
