Perceived
Pension fund failure is perceived as a remote, institutional risk — something that happens to steelworkers in the 1980s or municipal employees in Detroit. Most pension participants assume the Pension Benefit Guaranty Corporation backstops their benefits fully, unaware that PBGC guarantees have strict caps ($89,181 per year at age 65 for single-employer plans in 2025; far less for multiemployer plans). The 2021 American Rescue Plan's Special Financial Assistance program — which injected $69.5 billion into struggling multiemployer plans — temporarily reduced urgency, but the underlying structural problems (demographic shifts, optimistic return assumptions, chronic underfunding) remain. State and local pension underfunding is even less visible to participants, who rarely encounter their plan's funded ratio.
Rough estimate: Perceived as rare, institutional

Actual
~22% of state/local pension assets are unfunded ($1.3T gap); 130 multiemployer plans covering 1.3M people expected to exhaust funds within 20 years
US state and local government pension systems (Pew, FY2022)
Show derivation
The subgroup is the approximately 35 million Americans who participate in defined-benefit pension plans (private and public combined) — roughly 13.5% of ~260 million US adults. The 10% central estimate is conditional on being a DB participant, not a rate for all US adults. The Pew Charitable Trusts reports that state and local pension systems collectively carry $1.3 trillion in unfunded liabilities as of FY2022, with a median funded ratio of 78% (Equable, 2024). The PBGC's multiemployer program identified 130 plans covering 1.3 million people expected to exhaust their assets within 20 years. In the private sector, when PBGC takes over a terminated underfunded plan, benefits are capped at the guarantee maximum — meaning high-benefit workers (those earning above ~$89,000/year equivalent) lose a portion of their promised pension. For multiemployer plans, the guarantee is much lower ($12,870/year for 30 years of service), so benefit cuts upon PBGC takeover are substantial. The 10% estimate reflects: (a) 1.3M multiemployer participants facing near-certain benefit disruption (now mitigated by SFA, but SFA is time-limited); (b) an estimated 2-3M state/local participants in severely underfunded plans (funded ratio below 60%); and (c) the ongoing trickle of private single-employer plan terminations. Divided by the ~35M total DB participants, approximately 10-15% face material risk. If applied to all ~260M US adults, the unconditional probability would be roughly 1.4% (10% x 13.5%). The uncertainty range spans 5% (optimistic: SFA holds, investment returns meet assumptions, states increase contributions) to 20% (pessimistic: SFA exhausted, markets underperform, political will for contributions erodes).
Caveats: The 10% figure is conditional on being a defined-benefit pension participant (~3…
The 10% figure is conditional on being a defined-benefit pension participant (~35M people); applied to all US adults, the unconditional rate is roughly 1.4%. This entry is about institutional pension failure, not personal savings inadequacy (covered separately in retirement-savings-shortfall). The 10% estimate is approximate because pension risk materializes over decades and depends on investment returns, employer contributions, demographic shifts, and political decisions that are inherently unpredictable. The American Rescue Plan's $69.5 billion SFA intervention dramatically reduced near-term multiemployer risk, but SFA is a one-time appropriation designed to last roughly 30 years — it does not fix the structural underfunding. State and local pensions cannot legally default in most jurisdictions, but they can (and do) reduce benefits for new hires, increase employee contributions, and in some cases (e.g., Detroit, Puerto Rico) reduce benefits for current retirees through bankruptcy proceedings. The funded-ratio metric itself is sensitive to the discount rate assumption: using the plans' own assumed return (~7%) yields funded ratios around 78-82%, while using a risk-free rate (~4%) would show funded ratios closer to 40-50%, implying a much larger unfunded liability. The entry uses the plans' own assumptions for consistency with how funded status is reported, but the risk-free perspective suggests the problem is substantially larger than headline figures indicate.
Regional breakdown
The headline figure averages across very different populations. Here’s how the probability varies by geography or context:
| Region / context | Lifetime probability | Notes |
|---|---|---|
| Illinois, New Jersey, Kentucky (severely underfunded states) | 1 in 3.3 |
States with funded ratios below 50% face the highest risk of benefit reductions or contribution crises |
| Well-funded states (WI, SD, NY) | 1 in 33 |
States with funded ratios above 90% face minimal near-term risk to participant benefits |
| Multiemployer plans receiving SFA | 1 in 6.7 |
SFA provides temporary solvency but is designed to last approximately 30 years; long-term sustainability is uncertain |

State and local pension systems collectively carry $1.27 trillion in unfunded liabilities as of fiscal year 2022, according to Pew Charitable Trusts research — a sum equal to nearly 66% of their combined own-source revenue. The median funded ratio improved to 82.5% in 2025, buoyed by strong investment returns, but that median conceals enormous dispersion: Wisconsin and South Dakota sit above 100% funded, while Illinois, New Jersey, and Kentucky remain below 50%. In the private sector, the Pension Benefit Guaranty Corporation’s multiemployer program covers approximately 11 million participants across 1,335 plans, of which 130 plans covering 1.3 million people were expected to exhaust their assets within 20 years before Congress intervened.
That intervention — the American Rescue Plan’s Special Financial Assistance program — has approved $69.5 billion for financially troubled multiemployer plans covering about 1.2 million workers and retirees. SFA averted what would have been a catastrophic cascade of plan failures: without it, PBGC’s multiemployer insurance program was projected to become insolvent by 2025, which would have reduced guaranteed benefits to a maximum of $12,870 per year for someone with 30 years of service. The injection bought time, but it is a one-time appropriation designed to last roughly 30 years, not a permanent fix. The underlying demographic math — declining ratios of active workers to retirees, longer retirements, and return assumptions that may prove optimistic — has not changed.
The risk of material benefit reduction falls unevenly. An estimated 10% of the 35 million Americans in defined-benefit pensions face meaningful exposure: multiemployer participants in plans that received SFA (whose long-term solvency remains uncertain), state and local employees in severely underfunded systems, and private-sector retirees whose benefits exceed PBGC guarantee caps. For the majority of pension participants in well-funded plans, the risk is negligible. The danger is that participants in troubled plans do not know they are in troubled plans — funded-ratio disclosures are buried in actuarial reports that few participants read, and the political incentive is to defer contribution increases rather than acknowledge the gap. Pension underfunding is a slow-motion problem that becomes acute only when the checks stop clearing, by which point the options for retirees are severely limited.

An Increase in Pension Obligations Adds to States' Unfunded Liabilities- Statistic
States collectively reported $1.27 trillion in unfunded pension benefits in FY2022, equal to nearly 66% of combined own-source revenue- Excerpt
“"States collectively reported $1.27 trillion in unfunded pension benefits in fiscal 2022, equal to nearly 66% of their combined own-source revenue — almost 17 percentage points higher than just a year earlier. Unfunded pension liabilities grew largely because of lower-than-expected investment returns." ”

- Calculation
- Pew's state pension analysis provides the macro-level unfunding data. The $1.27 trillion gap and the 66% of own-source revenue ratio illustrate the structural burden. The 22% unfunded share (100% minus the ~78% median funded ratio) is used as the native figure. Individual state variation is enormous: some states are above 90% funded; Illinois, New Jersey, and Kentucky have been below 50%.

PBGC multiemployer program covers ~11 million participants in ~1,335 plans; $69.5 billion in Special Financial Assistance approved for plans covering ~1.2 million workers- Excerpt
“"The Multiemployer Program covers approximately 11 million participants in about 1,335 insured plans. As of November 1, 2024, PBGC has approved about $69.5 billion in Special Financial Assistance to financially troubled multiemployer plans that cover about 1.2 million workers and retirees." ”

- Calculation
- The PBGC annual report provides the official count of multiemployer plan participants and the scale of the SFA intervention. The 1.2 million workers receiving SFA support out of 11 million multiemployer participants (roughly 11%) gives a concrete measure of the share facing acute risk. Without SFA, the PBGC's multiemployer program was projected to become insolvent by 2025, which would have triggered benefit reductions to the guarantee maximum ($12,870/year for 30 years of service) for all participants in failed plans.
- Independence
- PBGC is the federal agency responsible for insuring private-sector defined-benefit pensions. Its data is administrative and independent from Pew's state/local pension analysis and from Equable's academic research.

National average funded ratio of public pension plans: 78% in 2024, improving to 82.5% in 2025; national shortfall shrank from $1.54T (2024) to $1.27T (2025)- Excerpt
“"Funded status in 2025 has shown moderate improvement, increasing to 82.5%, up from 78.0% in 2024. The national shortfall in assets for state and local pension plans shrank from $1.54 trillion in 2024 to an estimated $1.27 trillion." ”

- Calculation
- Equable provides the most granular plan-by-plan funded-ratio data. The 82.5% median funded ratio in 2025 masks wide dispersion: plans at or above 100% funded coexist with plans below 50%. The improvement from 78% to 82.5% was driven by strong 2024 investment returns, but Equable notes that "pension debt paralysis" — where contribution increases go primarily to servicing unfunded liabilities rather than building assets — remains a structural problem.
- Independence
- Equable is an independent research institute that calculates funded ratios using standardized assumptions, distinct from Pew's reliance on states' self-reported figures and from PBGC's private-sector-only scope.
