INDIANAPOLIS — Indiana is significantly more diverse in 2020 than in 2010. That echoes numbers seen in states around the country.
Those numbers could help determine control of the House in the 2022 elections and provide an electoral edge for years to come. The data will also shape how $1.5 trillion in annual federal spending is distributed.
They also show how diversity in the country is changing. The 2020 census found the white population is aging and has fallen to its smallest share of the total population on record.
Indiana also saw diversity dramatically increase from 32.3% in 2010 to 41.2% ten years later.
