Recent data reveals a troubling reality for American public pension systems: at least 41% of public pension plans are less than 70% funded, meaning that well over four in ten state and local pension systems lack sufficient assets to cover their long-term obligations to retirees. This underfunding crisis represents a decades-long accumulation of demographic shifts, investment shortfalls, and delayed contributions that now threatens the retirement security of millions of current and future pensioners. When a pension plan falls below 70% funding, it enters a precarious zone where even modest investment setbacks or demographic changes can trigger severe consequences for both beneficiaries and taxpayers.
The severity varies dramatically across the country. Some states maintain funding ratios in the 60s or even lower, while others maintain healthier positions. For example, certain Illinois pension systems have operated with funding ratios below 40%, forcing the state into massive catch-up contribution schedules that divert resources from schools, infrastructure, and other services. This isn’t merely an accounting issue—it directly affects whether retirees receive promised benefits and whether working public employees can trust the retirement promises made to them.

Why Are So Many Public Pension Plans Underfunded?
The roots of pension underfunding run deep and are multifaceted. Demographic changes have played a major role: Americans are living longer, which means pension obligations stretch further into the future. A pension system designed with the assumption that retirees would live to age 75 must now account for many living into their 90s. Simultaneously, birth rates have declined, reducing the ratio of active workers contributing to the system relative to retirees drawing benefits. This math problem alone would strain any pension system, but it has been compounded by other factors.
Investment returns have failed to meet assumptions in critical periods. Public pension plans typically assume 7% to 7.5% annual returns to fund their obligations. When markets underperform—as they did during the 2008 financial crisis and the 2020 pandemic downturn—the shortfall compounds over time. If a plan assumes $1 million will grow to $1.97 million over 10 years at 7% annual returns, but the market only delivers 4%, the plan suddenly faces a half-million-dollar gap. Many pension systems took years to recover from 2008, only to face new challenges in subsequent market volatility.

The Scale of Underfunding and What It Means
The breadth of this problem cannot be overstated. When 41% of plans are underfunded below the 70% threshold, that represents a systemic issue affecting major metropolitan areas and entire states, not just a few isolated cases. The total unfunded liability across all public pension systems has been estimated at over $1 trillion, though precise figures are difficult to pin down because accounting methods vary and some plans are more transparent than others. A critical limitation in understanding the true scope is that not all states use identical accounting standards—some use more optimistic assumptions about future investment returns, which can mask the true severity of underfunding.
The “80% funded” threshold is often cited as a warning level, but 70% funding is genuinely dangerous territory. At that level, small setbacks become major crises. A 10% market correction hits harder on an already-stressed balance sheet. A larger-than-expected retiree population shift forces immediate contribution increases. The compounding effect works against the plan: the further it falls behind, the higher contribution rates must climb to catch up, which can strain government budgets and reduce resources available for other services.
Impact on Current Workers and Retirees
The underfunding crisis doesn’t affect all participants equally. For retirees already receiving benefits, the risk varies by state. Some states have constitutional protections for pension benefits, making benefit cuts legally difficult. Others have more flexibility to reduce cost-of-living adjustments or implement other changes. Michigan, for instance, changed its public pension system rules significantly in the 1990s, shifting new workers to defined-contribution plans rather than traditional pensions.
Current retirees in well-funded systems like Wisconsin’s may sleep soundly; those in Illinois or Kentucky systems with much lower funding ratios have legitimate concerns about whether their benefits will remain intact. Current workers face a different but equally serious problem. Many public employees have been promised a pension as part of their compensation package, but work in a system that isn’t on track to deliver. A teacher in a 50%-funded plan might work for 30 years expecting a secure retirement, only to discover that the state cannot pay benefits at promised levels. Younger workers are particularly vulnerable because they’re carrying the burden of previous decades of underfunding while also facing the long-term underfunding of their own benefits. Some states have responded by shifting new employees into hybrid or defined-contribution plans, essentially abandoning the pension promise for future workers while leaving current employees exposed.

What Approaches Are Being Used to Address Pension Underfunding?
States have attempted various strategies to address underfunding, with mixed results. The most direct approach is simply paying more: increasing employer contributions and, in some cases, asking employees to contribute more as well. New Jersey has sharply increased its pension contributions over the past decade, though this has consumed a growing portion of the state budget. Another approach involves adjusting benefits—increasing retirement ages, reducing cost-of-living adjustments, or changing benefit formulas for new employees.
Colorado implemented a hybrid model for new hires that includes both a reduced pension component and a defined-contribution component. A third strategy involves changing investment policy or hiring new investment managers to chase higher returns, though this carries its own risks. Some systems have increased allocation to alternatives like private equity and hedge funds, betting that higher returns will solve the funding problem. This approach has a significant tradeoff: while these investments can produce higher returns in bull markets, they also introduce more volatility and are less liquid, potentially creating problems during downturns when the system needs cash. Additionally, the fees charged by alternative investment managers can be substantially higher than passive index funds, meaning some of the gains go to Wall Street instead of strengthening the pension fund.
The Investment Return Assumption Problem
One of the most critical—and underappreciated—aspects of pension underfunding is the assumption problem. Public pension plans typically assume they’ll earn 7% to 7.5% annually. In a low-interest-rate environment, particularly when Treasury bonds are yielding 3% to 4%, achieving 7% requires taking substantially more risk. This creates a dangerous dynamic: systems are forced to chase returns by taking bigger bets on stocks, private equity, and other volatile assets. If those bets pay off, the system stays solvent.
If they don’t, the shortfall widens dramatically. A critical warning: this system is essentially gambling with retirees’ security. When a pension system invests aggressively to meet an assumed return target, it’s not choosing a balanced portfolio based on actual liabilities and risk tolerance—it’s choosing risk out of necessity. During the last decade of generally favorable markets, this strategy worked. But a sustained bear market could push many marginally-funded systems into crisis territory quickly. Furthermore, some pension boards have been slow to reduce their return assumptions even when market conditions clearly don’t support them, essentially hoping for outcomes that seem increasingly unrealistic.

Geographic Variations and State-by-State Funding Crises
Underfunding is not evenly distributed. Some states have managed their pensions relatively well and maintain funding ratios above 80%, while others face severe crises. Illinois, as mentioned, has some of the worst-funded systems in the nation. The state’s pension systems for teachers, public employees, and judges have combined unfunded liabilities exceeding $300 billion, with some individual systems operating at less than 40% funding.
This crisis has driven discussion of federal bailouts and even bankruptcy restructuring, options that would have been unthinkable a generation ago. Kentucky, New Jersey, Connecticut, and several other states also face severe challenges. At the other end of the spectrum, Wisconsin maintains relatively healthy pension funding, as does South Dakota, which has benefited from consistent funding discipline and favorable investment returns over several decades. The geographic variation reflects different policy choices, different demographic profiles, and different luck with market timing. A state that happened to have favorable investment returns in the 2010s looks far better than one that suffered large losses in 2008 and didn’t recover as quickly.
The Future Outlook for Pension Systems
Looking forward, the pension funding crisis will likely remain a defining fiscal challenge for states and municipalities for the next two decades. Even with optimistic assumptions about economic growth and investment returns, many systems cannot return to full funding without significant changes. Some experts predict that states will be forced to choose between cutting other services, raising taxes, reducing benefits, or some combination of the three. A few states have begun exploring more radical restructuring, including converting portions of traditional pensions to defined-contribution plans or hybrid arrangements.
The federal government has remained largely hands-off, treating pension funding as a state and local responsibility. However, as more systems approach true crisis conditions, pressure for federal intervention may grow. Whether that intervention would come through increased federal pension insurance protections, direct bailouts, or simply relaxed accounting rules to make problems less visible remains to be seen. The one certainty is that this issue will dominate state and local budget discussions for years to come.
Conclusion
The reality that at least 41% of public pension plans operate below 70% funding represents a structural crisis with real consequences for millions of Americans. This underfunding stems from long-term demographic trends, investment shortfalls, delayed funding decisions, and unrealistic return assumptions. The crisis affects retirees depending on pension income, workers expecting a secure retirement, and taxpayers who ultimately bear responsibility for making up shortfalls through higher taxes or cuts to other services.
For individuals depending on public pensions, the immediate priority is understanding the specific funding status of your state’s pension system and what protections exist in your state’s legal framework. For those still working in the public sector, this environment argues for diversifying retirement security strategies rather than relying entirely on pension promises. For states and municipalities, addressing underfunding requires difficult choices about contributions, benefits, and investment strategy—and those choices should be made now rather than deferred to future leaders dealing with even larger crises.
Frequently Asked Questions
How do I find out if my state’s pension system is adequately funded?
Most state pension systems publish detailed annual reports available on their websites. These reports include actuarial valuations and funding ratios. You can also consult resources from the Public Pension Coordination Council or similar state-specific pension oversight bodies, which often provide plain-language summaries of system health.
If a pension system is severely underfunded, could my benefits be cut?
It depends on your state’s legal protections and the severity of the funding crisis. Some states have constitutional provisions protecting pension benefits from reduction. Others have more flexibility. In extreme cases, benefit modifications have occurred, particularly through changes to cost-of-living adjustments. Once you’re receiving benefits, state law typically provides more protection than for future benefits.
What’s the difference between “funding ratio” and “funded status”?
They’re essentially the same thing. The funding ratio (or funded status) is the percentage of a pension plan’s liabilities that are covered by current assets. A 70% funded plan has assets covering 70 cents of every dollar of promised benefits.
Should I rely on my public pension for retirement?
You should certainly claim the benefits you’ve earned, but treating a pension as your only retirement income source is risky if your system is underfunded. Consider it one component of retirement security and maintain additional savings if possible.
Why do pension systems assume such high investment returns?
Historically, 7% returns reflected actual long-term market performance. However, in a lower-interest-rate environment, achieving those returns requires taking more risk. Some systems have been slow to adjust assumptions downward, creating a mismatch between assumed returns and realistic market expectations.
Could the federal government bail out state pension systems?
There is no formal federal bailout mechanism for state pensions. While it’s theoretically possible, it would require congressional action and would likely be controversial. States are primarily responsible for their own pension obligations.
