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.

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.
