Demand: the older population

Supply: licensed beds
| Setting | Beds | Per 1,000 aged 75+ | Per 1,000 aged 85+ | Source |
|---|---|---|---|---|
| Nursing homes (Medicare or Medicaid certified) | 5,848 | 77.9 | 277.4 | CMS, September 2026 |
| Residential care / assisted living | 4,700 | 62.6 | 222.9 | CDC survey, 2020 |
US: 222.6 nursing beds and 170.1 assisted living beds per 1,000 aged 85+. Assisted living beds are CDC's 2020 survey estimate, its latest with state detail, set against 2025 population, so the ratio understates any supply added since.

- Notes
- SD has historically had a nursing-facility bed moratorium outside CON.
From NCSL's certificate of need table (updated April 29, 2025, covering January 2025) with later changes checked on state sites on October 24, 2026. "Not listed" means NCSL does not name assisted living, not that it is exempt. Confirm with the state health planning agency before relying on it. HUD requires a state CON for nursing home beds where the state has one (Handbook 4232.1, 2.5.EE).
