24 South Dakota Districts Hit Record Lows

Wed, 18 Feb 2026 12:00:00 GMT

Rapid City Area Schools^↗, the second-largest district in South Dakota, enrolled 12,040 students in 2024-25. That is the lowest figure in the district's recorded history, down 13.9% from its 2012 peak of 13,982. Rapid City is not alone. Twenty-four South Dakota school districts are at their all-time enrollment lows, and collectively they serve 25,019 students, 18.0% of the state's total. At the same time, 20 districts sit at all-time highs, nearly all of them in the Sioux Falls^↗ suburban ring.

The split captures a state pulling apart. South Dakota added students for 12 consecutive years, from 122,384 in 2006-07 through 2018-19, dipped briefly in 2019-20, then rebounded to a peak of 141,429 in 2021-22. That growth era is over. The state has now declined for three straight years, losing 2,568 students since the peak, with 2024-25's drop of 1,726 the steepest in at least 18 years.

The two South Dakotas

The 24 districts at record lows and 20 at record highs occupy different economic universes. The record-high districts are overwhelmingly in the Sioux Falls metro, led by Harrisburg^↗ (6,398 students, up 272.8% since 2006-07), Brandon Valley^↗ (5,206, up 72.5%), and Tea Area^↗ (2,514, up 111.3%). Sioux Falls itself has essentially plateaued at 24,841, down slightly from its 2022-23 peak of 25,228. The growth is in the suburban ring, not the city center.

The record-low districts span western South Dakota, reservation communities, and small towns. After Rapid City, the largest are Watertown^↗ (3,425, down 14.7% from its 2015 peak), Todd County^↗ (1,956, down 9.3% from 2020), and Custer^↗ (854, down 10.6% from 2018). Several smaller districts have lost a quarter to two-thirds of their peak enrollment: Bowdle^↗ is down to 45 students from a peak of 147, a 69.4% decline. Newell^↗ has fallen 42.4%, Lead-Deadwood^↗ 34.0%.

Rapid City's long slide

Rapid City peaked at 13,982 students in 2011-12 and has been unable to recover. The district has now declined in six consecutive reporting years (excluding 2020-21, for which data is incomplete). It lost 800 students in the single year from 2018-19 to 2019-20, then continued bleeding at a slower pace: 66, 310, 120, and 273 in the years since.

The losses are not simply a function of population decline. A Rapid City Area Schools board member told the Rapid City Journal that "people are moving here with their families" but "not enrolling in our schools, or they're pulling them out." The district has lost approximately 1,700 students over the past decade while homeschool and private school enrollment has grown.

That pattern is statewide. South Dakota's home-schooled student population rose 143% from 4,333 to 10,536 between 2015-16 and 2023-24, the largest proportional increase of any state reporting data for every year in that range. At roughly $7,000 per student in state funding, the shift represents tens of millions in annual revenue that has moved out of the public system.

Where the growth went

While Rapid City contracted, the Sioux Falls suburban ring exploded. Harrisburg added an average of 260 students per year over the past 18 years, growing from 1,716 to 6,398. It has built nearly one new building every two years to keep pace, at an average construction cost of $166 per square foot, well below the $287 regional average.

Brandon Valley and Tea Area followed a similar trajectory, more than doubling since 2006-07. Sioux Falls, by contrast, has grown just 24.2% over the same period and posted its second consecutive year of decline in 2024-25.

The pattern is a classic suburban donut: the core district plateaus or declines while surrounding communities absorb new residential development. South Dakota's unrestricted open enrollment policy allows families to send children to any public school in the state regardless of residence, which may accelerate the sorting. Families who remain within Sioux Falls city limits can still enroll in Harrisburg or Brandon Valley.

Small districts and reservation schools

The deepest percentage declines are concentrated in districts under 500 students. Lead-Deadwood, the historic Black Hills mining district, has fallen from 894 to 590 students since 2011, a 34.0% decline and the steepest among mid-sized districts at record lows. Superintendent Dr. Erik Person attributed the challenges to housing shortages, telling KOTA Territory News that recent population growth in the Lead and Deadwood area "doesn't really help with enrollment" because many newcomers are retirees buying second homes.

Todd County, which serves the Rosebud Indian Reservation, has declined from 2,156 to 1,956 since 2019-20. The district faces compounding challenges beyond enrollment numbers: chronic absenteeism reached 71% in 2023-24, with the median household income of $33,800 less than half the state average. Todd County High School Principal Randy Pirner told Dakota News Now that "COVID set us back 10 years because kids who aren't going to school in kindergarten aren't going to be going to school when we get them in high school."

Watertown, the state's seventh-largest district at 3,425 students, is considering closing one of its five elementary schools as enrollment continues to fall. The district has lost 591 students, 14.7%, since its 2015 peak, driven in part by declining birth rates in Codington County.

The acceleration problem

The year-over-year data tells the sharpest story. South Dakota gained between 1,000 and 2,200 students every year from 2009-10 through 2018-19, with smaller gains in the two years before and a dip of 288 in 2019-20. The 2021-22 rebound of 2,275 looked like a return to form. Instead, the state lost 424 in 2022-23, 418 in 2023-24, and 1,726 in 2024-25. The decline is accelerating: last year's loss was four times larger than either of the two preceding years.

Statewide, exactly half of South Dakota's 146 districts with comparable data declined between 2019-20 and 2024-25 (73 districts), while 72 grew and one was flat. The losses and gains nearly cancel out in aggregate, but the distribution is lopsided: declining districts collectively lost 4,490 students while growing districts gained 4,416. The state's net loss of 74 students over five years masks deep geographic divergence.

South Dakota's state demographer, Weiwei Zhang, has projected that children will drop below 20% of the state's population by 2030, while adults over 65 will surpass 20%. The state's birth rate has fallen from 15 per 1,000 in 2007 to 12 per 1,000. Even with relatively high fertility by national standards, the kindergarten pipeline is shrinking.

Redfield^↗ has declined for eight consecutive years. Lead-Deadwood for seven. Rapid City for six. None show signs of turning around. For Bowdle, at 45 students, the arithmetic is existential: one more family leaving could trigger the state's mandatory reorganization planning threshold. For Watertown, at 3,425 and eyeing an elementary school closure, the decisions are about which building goes dark and which bus routes get cut. None of these choices can be reversed easily if the students return. Most will not.
