South Dakota ranks fourth in the nation for the percentage of residents who identify as Native American.
As of the 2020 census, almost 100,000 people in South Dakota identify at least partially as Native American – 11.1% of the population (98,842 total).
Alaska has the highest percentage (22%), followed by Oklahoma (16%) and New Mexico (12%).
In 1980, 6.5% of South Dakota was Native American (44,948) – the third highest-percentage in the country.
Indigenous people make up more than 50% of the population in nine South Dakota counties, with the highest percentage being Oglala Lakota County on the Pine Ridge Indian Reservation at 95.6%.
Native Americans have been undercounted in the official U.S. Census historically. In 2010, for instance, the Census estimated that the population was undercounted by 4.9%. The Census moved the response deadline up 30 days in 2020, prompting concerns that the earlier deadline would lead to greater undercounts.
