Population At the 2022 estimate South Dakota's population was 909,824 on July 1, 2022, a 2.61% increase since the
2020 United States census. In 2020, 6.5% of South Dakota's population was reported as under 5, 24.5% under 18, and 17.7% were 65 or older. Females made up approximately 49.7% of the population. The top countries of origin for South Dakota's immigrants and refugees in 2018 were
Guatemala, the
Philippines,
Mexico,
Sudan and
Ethiopia. The
center of population of South Dakota is in
Buffalo County, in the unincorporated county seat of
Gann Valley. According to
HUD's 2022
Annual Homeless Assessment Report, there were an estimated 1,389
homeless people in South Dakota. In 2022, South Dakota had the lowest drug overdose death rate of any US state, at 11.3 per 100,000 people.
Race or Hispanic Origin (U.S. Census) According to the 2022 census estimate, the racial composition of the population was: • 84.2% White alone, percent • 2.6% Black or African American alone, percent • 8.5% American Indian and Alaska Native alone, percent • 1.8% Asian alone, percent • 0.1% Native Hawaiian and Other Pacific Islander alone, percent • 2.8% Two or More Races, percent • 4.9% Hispanic or Latino, percent • 80.7% White alone, not Hispanic or Latino, percent Source: Ethnically, 4.9% of South Dakota's population was of
Hispanic, Latino, or Spanish origin (they may be of any race). Ethnicity for the remainder of the population is not similarly accounted by the federal government. According to the U.S. Census Bureau, 25.4% of South Dakota's population younger than age 1 were 'minorities' as of 2011, meaning they had at least one parent who was not non-Hispanic white.
Ethnicity and Place of Origin As of 2000, the five largest ancestry groups in South Dakota are
German (40.7%),
Norwegian (15.3%),
Irish (10.4%),
Native American (8.3%), and
English (7.1%). German Americans are the largest ancestry group in most parts of the state, especially in East River (east of the Missouri River), although there are also large Scandinavian-descended populations in some counties. South Dakota has the nation's largest population of
Hutterites, a communal
Anabaptist group which emigrated in 1874 from German-speaking villages in what today is
Ukraine but at that time was part of the
Russian Empire. s in South Dakota
American Indians, largely
Lakota,
Dakota, and
Nakota (Sioux), are predominant in several counties and constitute 20 percent of the population in
West River. The seven large Indian reservations in the state occupy an area much diminished from their former
Great Sioux Reservation of West River, which the federal government had once allocated to the Sioux tribes. South Dakota has the third-highest proportion of Native Americans of any state, behind Alaska and
New Mexico. Five of the state's counties are wholly within the boundaries of sovereign
Indian reservations. Because of the limitations of climate and land, and isolation from urban areas with more employment opportunities, living standards on many South Dakota reservations are often far below the national average;
Ziebach County ranked as the poorest county in the nation in 2009. The unemployment rate in
Fort Thompson, on the
Crow Creek Reservation, is 70%, and 21% of households lack plumbing or basic kitchen appliances. A 1995 study by the U.S. Census Bureau found 58% of homes on the
Pine Ridge Indian Reservation did not have a telephone. The reservations' isolation also inhibits their ability to generate revenue from gaming casinos, an avenue that has proved profitable for many tribes closer to urban centers.
Languages In 1995, the legislature passed a law to make English the "common language" of the state. Since 2019,
"the language of the Great Sioux Nation, three dialects, Dakota, Lakota, and Nakota" is the official indigenous language. As of 2010, 93.46% (692,504) of South Dakota residents age5 and older spoke
English as their
primary language. 6.54% of the population spoke a language other than English. 2.06% (15,292) of the population spoke Spanish, 1.39% (10,282) spoke
Dakota, and 1.37% (10,140) spoke German. Other languages spoken included
Vietnamese (0.16%),
Chinese (0.12%), and
Russian (0.10%).
Growth and rural flight Over the last several decades, the population in many rural areas has declined in South Dakota, in common with other Great Plains states. The change has been characterized as "
rural flight" as family farming has declined. Young people have moved to cities for other employment. This trend has continued in recent years, with 30 of South Dakota's counties losing population between the 1990 and the 2000 census. During that time, nine counties had a population loss of greater than 10%, with
Harding County, in the northwest corner of the state, losing nearly 19% of its population. compared with a national rate of 12.8%. The effect of rural flight has not been spread evenly through South Dakota, however. Although most rural counties and small towns have lost population, the Sioux Falls area, the larger counties along
Interstate 29, the Black Hills, and many
Indian reservations have all gained population.
Lincoln County near Sioux Falls was the seventh fastest-growing county (by percentage) in the United States in 2010. The growth in these areas has compensated for losses in the rest of the state.
Religion According to the
Public Religion Research Institute in 2020, 73% of the adult population were Christian. Per the
Pew Research Center's separate 2014 study, the largest
religious denominations in Christianity by number of adherents as a percentage of South Dakota's population in 2014 were the Catholic Church with 22 percent, evangelical Protestants with 25 percent, and mainline Protestants with 32 percent. Together, all kinds of Protestants accounted for 57 percent. Those unaffiliated with any religion represented 18 percent of the population. The breakdown of other religions was <1% Muslim, <1% Hindu and 1% Buddhist. The number of
Jewish people in South Dakota is under 400, the lowest total in any of the fifty states. The largest Christian denominations by number of adherents in 2010 were the Roman Catholic Church with 148,883 members; the
Evangelical Lutheran Church in America (ELCA) with 112,649 members; and the
United Methodist Church (UMC) with 36,020 members. The ELCA and UMC are specific denominations within the broader terms 'Lutheran' and 'Methodist', respectively. Through the
Association of Religion Data Archives in 2020, Catholicism remained the largest Christian denomination, followed by the ELCA. Non-denominational Protestants numbered 63,992, becoming the third largest group of Christians throughout the state. In 2022, the Public Religion Research Institute determined 72% of the state were Christian altogether, though Protestants were 48%, Catholics 22%, and Jehovah's Witnesses 2%. The religiously unaffiliated declined from 22% to 21% between 2020 and 2022. Other non-Christian faith groups with a substantial presence in the South Dakota were
Buddhism (3%),
New Age (3%), and others at 1% altogether. Through the Association of Religion Data Archives 2020 study, there were 978 adherents to the
Baha'i Faith and 535
Muslims. ==Economy==
