America at 250: South Dakota Uncovered — 20 Facts About the Mount Rushmore State, Home of Four Presidents Carved in Stone

As the United States celebrates 250 years of independence, a state-by-state journey — from Mount Rushmore and the Black Hills to the Badlands, the Sturgis rally and no state income tax — through the numbers, the history and the emergency lifelines every traveler should carry.

As the United States marks the landmark 250th anniversary of the Declaration of Independence in 2026 — its semiquincentennial — our state-by-state journey reaches South Dakota: the “Mount Rushmore State,” where four American presidents gaze out from a granite cliff in the Black Hills. Few images capture the nation’s reverence for its own history like Rushmore, making South Dakota an especially fitting stop in this anniversary year.

A Northern Plains state of prairie, buttes and sacred Lakota lands, South Dakota blends frontier heritage with wide-open beauty. What follows is a fact-checked portrait drawn from official sources — the U.S. Census Bureau, the Bureau of Economic Analysis, state agencies and federal registries — followed by the safety information every visitor to the Mount Rushmore State should keep close at hand.

How Big Is South Dakota? About 925,000 People Across 77,116 Square Miles

South Dakota is a large but lightly populated Plains state. The U.S. Census Bureau estimated its population at nearly 925,000 in 2024, ranking it around 5th-smallest, spread across roughly 77,116 square miles — the 17th-largest state by area — of prairie, river valleys and the forested Black Hills.

The largest city is Sioux Falls, a fast-growing financial and health-care center in the east, followed by Rapid City, the gateway to the Black Hills in the west, and the capital, Pierre. The Missouri River bisects the state, dividing the more agricultural “East River” from the ranching and Native American country of “West River.”

South Dakota’s landscape ranges from the fertile eastern prairie and glacial lakes to the striking, eroded spires of the Badlands and the pine-covered Black Hills — the highest mountains east of the Rockies, sacred to the Lakota and home to both Mount Rushmore and the massive, still-unfinished Crazy Horse Memorial.

A Northern Plains History: The 40th State, Admitted in 1889

The Black Hills and plains of South Dakota are the ancestral and sacred land of the Lakota (Sioux) nation, and the state’s history is inseparable from theirs — from the 1868 Fort Laramie Treaty to the discovery of gold that brought a rush of miners, to the tragedy at Wounded Knee in 1890. Great leaders such as Sitting Bull and Crazy Horse are central to this history.

South Dakota was admitted as the 40th state on November 2, 1889 — the same day as North Dakota. The Homestead Act drew farmers to the eastern prairie, gold built Black Hills towns like Deadwood (of Wild West fame), and in the 20th century the carving of Mount Rushmore (1927–1941) gave the state its enduring symbol and its nickname.

The Economy: About $70 Billion GDP From Farms to Finance

South Dakota’s economy, with a GDP of roughly $70 billion (about $57 billion in inflation-adjusted terms), is productive for its small population. Agriculture is foundational — the state is a major producer of cattle, corn, soybeans, wheat and sunflowers, and ranching and farming define much of the landscape.

But South Dakota has also become a surprising financial center. In 1981, the state eliminated caps on interest rates and, combined with the absence of a state income tax, drew the credit-card operations of major banks (Citibank moved its card business to Sioux Falls) — and, more recently, made South Dakota a global capital for trusts and wealth management. Tourism, centered on the Black Hills, Mount Rushmore, the Badlands and the Sturgis Motorcycle Rally, is another major pillar.

That mix has powered rapid growth in Sioux Falls, one of the fastest-growing cities in the Midwest, and given the state one of the lowest unemployment rates and steadiest budgets in the nation. Food processing, biotechnology and defense (Ellsworth Air Force Base near Rapid City) add further ballast, while the state’s farms and ranches export grain, beef and pork around the world — proof that a small-population state can wield outsized economic weight.

Schools and Universities: About 145,000 Pupils and the Coyotes and Jackrabbits

South Dakota’s public schools enroll roughly 145,000 K-12 students, many in small rural districts across the plains and on the state’s Native American reservations.

In higher education, the University of South Dakota in Vermillion (the Coyotes, home to the state’s law and medical schools) and South Dakota State University in Brookings (the Jackrabbits, the land-grant agricultural and engineering university) anchor the system, alongside the South Dakota School of Mines & Technology in Rapid City and tribal colleges serving Native communities.

Hospitals and Health Care: About 55 Hospitals

South Dakota has roughly 55 hospitals, many of them small critical-access facilities serving rural communities. The state is notably the home base of Sanford Health, one of the largest rural health systems in the country, headquartered in Sioux Falls, along with the Avera and Monument Health systems.

Delivering care across South Dakota’s vast rural distances, and to its reservation communities through the Indian Health Service, is a defining challenge, addressed through critical-access hospitals, regional centers and telemedicine. The South Dakota Department of Health coordinates statewide public-health services.

Getting Around: Regional Airports and the Black Hills

South Dakota’s busiest airport is Sioux Falls Regional Airport in the east, with Rapid City Regional serving the Black Hills, plus a network of smaller airfields across the state. These connect South Dakota to hubs like Denver, Minneapolis and Chicago.

On the ground, Interstate 90 crosses the entire state east–west (passing the Badlands, Wall Drug and the Black Hills), and Interstate 29 runs north–south along the eastern edge. Much travel is on long two-lane highways, and scenic drives like the Needles Highway and Iron Mountain Road in the Black Hills are attractions in themselves.

Culture: Mount Rushmore, the Badlands and Sturgis

South Dakota’s culture is defined by its monumental landscapes and frontier heritage. Mount Rushmore National Memorial — the 60-foot faces of Washington, Jefferson, Lincoln and Theodore Roosevelt — draws millions of visitors, and the nearby Crazy Horse Memorial honors Native American heritage on an even grander scale. The Badlands, Wind Cave and Custer State Park showcase the state’s natural wonders and its bison herds.

Each August, the Sturgis Motorcycle Rally brings hundreds of thousands of riders from around the world to the Black Hills, one of the largest motorcycle gatherings on Earth. The Wild West lore of Deadwood, the roadside legend of Wall Drug, and the enduring Lakota cultural presence all shape the state’s identity.

Sport and the Outdoors: College Rivalries and the Great Outdoors

South Dakota has no major professional franchise, so college sports — led by the University of South Dakota Coyotes and South Dakota State Jackrabbits, whose rivalry animates the state — provide the main spectacle, along with minor-league and amateur sports.

Outdoors, South Dakota is a paradise for hunting (it is one of the nation’s premier pheasant-hunting destinations), fishing, hiking and camping in the Black Hills, and exploring the Badlands, Custer State Park’s bison, and the Missouri River reservoirs. The state’s wide-open spaces and dark skies draw visitors seeking room to roam.

Faith and Places of Worship: Hundreds of Congregations

South Dakota’s religious landscape reflects its immigrant farming heritage and Native traditions. Protestant denominations — especially Lutheran, brought by Scandinavian and German settlers — and a large Roman Catholic population (including German-Russian Catholics) are the largest groups, alongside Native American spiritual traditions on the state’s reservations.

Because no single official registry counts every congregation, the closest reliable measures come from religious censuses and the U.S. Census Bureau’s County Business Patterns data on religious organizations, which together point to hundreds of congregations across the state’s cities, small towns and reservations.

The Justice System: About 3,400 People Incarcerated

The South Dakota Department of Corrections holds roughly 3,400 people, a small system in absolute terms but with an incarceration rate elevated in part by the over-representation of Native Americans — a longstanding concern in the state’s justice system.

South Dakota has pursued sentencing and reentry reforms, and the state has invested in a new state penitentiary to replace its aging main prison in Sioux Falls. Community supervision and treatment programs supplement its prisons.

5 South Dakota Laws and Distinctions That Set It Apart

South Dakota’s frontier heritage and pro-business policies produce several distinctive features:

1. No state income tax: South Dakota levies no personal or corporate income tax, a cornerstone of its economic strategy.

2. A global trust haven: South Dakota’s trust laws — allowing perpetual “dynasty” trusts and strong privacy — have made it one of the world’s leading destinations for wealth management, drawing assets from around the globe.

3. Mount Rushmore: South Dakota is home to the nation’s most famous monument to its presidents, carved into the sacred Black Hills.

4. Abortion: South Dakota enforces a near-total abortion ban that took effect after the 2022 reversal of Roe v. Wade.

5. Permitless carry: South Dakota allows eligible adults to carry concealed firearms without a permit.

Famous South Dakotans: Notable Talent From the Mount Rushmore State

South Dakota has produced a notable roster of figures. Legendary television journalist Tom Brokaw, longtime anchor of NBC Nightly News, was born in Webster, and actress January Jones of “Mad Men” fame in Sioux Falls. Entertainment personality Mary Hart also hailed from the state.

South Dakota’s deepest historical figures, though, are the great Lakota leaders — Sitting Bull and Crazy Horse — whose resistance and legacy are honored across the state, including at the monumental Crazy Horse Memorial. From the newsroom to the Great Plains, the Mount Rushmore State’s story looms large in the American imagination.

Who Runs South Dakota? Governor Larry Rhoden and State Leadership

South Dakota’s executive branch is led by Governor Larry Rhoden, a Republican who became the 34th governor in January 2025, elevating from lieutenant governor when Kristi Noem resigned to become U.S. Secretary of Homeland Security. A rancher and longtime state legislator from the ranching country of western South Dakota, Rhoden has emphasized agriculture, the trades and steady governance.

South Dakota’s government features several independently elected statewide officials alongside the Governor, plus appointed department heads. Key members of state leadership include:
