How South Dakota Retirement System Funded Ratio Compares
Plan Funded Ratio 78.1%
National avg
A ratio of 78.1% compared against the national public-pension average of 75.5%.
Healthy Threshold
Plans above 80% are generally considered adequately funded by NASRA standards.
Participant Composition
The active-to-retiree ratio is a leading indicator of long-term plan sustainability, plans with more retirees than active contributors face mounting cash-flow pressure as benefit payments outpace incoming contributions.
Investment Policy Mix
Public pension plans report their asset allocation in their annual CAFR and actuarial valuation. Equity-heavy mixes capture market upside but introduce volatility; fixed-income tilts protect funded status during downturns at the cost of long-run return.

Where this data comes from + how funding gaps get resolved
These figures come from the Public Plans Database, a collaboration between the Boston College Center for Retirement Research and NASRA that compiles them from each plan's Comprehensive Annual Financial Reports (CAFRs) and actuarial valuations. The relationship between contribution adequacy and investment performance determines whether an unfunded liability narrows or expands year over year, and the gap itself is typically closed through some combination of higher contributions, investment returns, or benefit modifications. See our methodology for how public-pension funding differs from ERISA-backed private plans, and our disclaimer below before acting on this data.
