Imagine a future Wisconsin where one in seven people speak Spanish and diverse neighborhoods mirroring big cities like Milwaukee are the norm. That's the vision suggested by new data pointing to dramatic racial and ethnic changes across the state and nation in decades to come.

The interactive map below uses a national Diversity Index developed by USA Today to show the chances that the next person you meet will be of a different race or ethnic background.

Slide the timeline bar left or right to see how those chances have changed or will change in the future. To drill deeper into the population data on a county level, scroll down to the search box below the map.
