The 2000 U.S. Census found about 20,000 Hoosiers of American Indian ancestry, some of them members of indigenous tribes such as the Miami or the Wea. Others are members of the Pottawatomie or Shawnee who moved to Indiana from nearby states under pressure from white pioneers. Former chairman of the state’s Native American Indian Affairs Commission and Miami Chief Brian Buchanan, said there are more than 42,000 American Indians living in the state.
