What the Data Says About South Dakota Public Pensions
South Dakota currently sponsors 3 public pension plans tracked by the Public Plans Database (PPD), covering a combined 89,978 active employees and retirees across teacher, police-and-fire, municipal, and general state systems. The weighted average funded ratio across these 3 plans is 56.6%, with a combined unfunded liability of $5.05B. These disclosures derive from each plan's CAFR and actuarial valuation, compiled by NASRA and Boston College's Center for Retirement Research.
South Dakota's average funded ratio falls well below the national public-pension average of 75.5%, signaling a structural funding gap that typically requires a combination of higher employer contributions, revised actuarial assumptions, and in some cases legislated benefit reforms to stabilize. The $5.05B unfunded liability represents the actuarial shortfall between projected obligations and current assets across all 3 plans, which flows through to state and local budgets over time as amortization payments.
Unlike private-sector pensions, which fall under ERISA and are backstopped by the Pension Benefit Guaranty Corporation (PBGC), South Dakota's public plans rely on the full faith and credit of the sponsoring government entity. That distinction matters for the 89,978 South Dakota workers and retirees covered by these systems: funding shortfalls are addressed through state and local budget decisions rather than federal insurance.
