Racial and Ethnic Diversity by State: 2025 Census Estimates
The U.S. Census Bureau’s Vintage 2025 population estimates, released in June 2026, provide updated state-level data on race and Hispanic origin from April 1, 2020 to July 1, 2025. These estimates allow analysts to track racial and ethnic diversity across states, building on the 2020 Census diversity index. Hawaii, California, Nevada, and Maryland remain among the most diverse states, while Maine, Vermont, and West Virginia continue to have the lowest diversity levels.
