America's Vanishing Workers: 720,000 Left the Workforce in a Single Month. Nobody Agrees Why.
## The lowest labor force participation rate in 50 years (outside a pandemic) has economists locked in a fierce debate—is it a supply crisis, a demand failure, or something else entirely?

### Introduction: The Great Disappearing Act
It was supposed to be a routine jobs report. Instead, it became one of the most hotly debated economic data releases in recent memory.
On July 2, 2026, the Bureau of Labor Statistics dropped a bombshell: the U.S. economy added just 57,000 jobs in June, far below expectations. But that wasn't the shock. The real shock came from a different number: **720,000 people left the labor force in a single month**.
The labor force participation rate—the percentage of Americans 16 and older who are working or actively looking for work—plunged to **61.5%**. Outside the depths of the COVID-19 pandemic, that's the lowest reading in **five decades**.
Over the past year, about **1 million workers have thrown in the towel**. Since President Donald Trump returned to office, the workforce has declined by about **1.3 million people**. About **1.5 million fewer people were working in June than in January 2025** at the start of his second term.
But here's where the story gets interesting—and deeply contentious. **Experts cannot agree on why it's happening.**

### The "Supply Crisis" Theory: There Just Aren't Enough Workers
One camp of economists argues that the decline in labor force participation isn't about workers giving up. It's about a **structural shortage of available workers**.
**Laura Ullrich**, director of economics at Indeed Hiring Lab and a former Richmond Fed economist, has emerged as the leading voice of this view. She told Fortune that the June data should not be viewed simply as discouraged workers throwing in the towel.
> "Historically, you've been able to look at jobs numbers ... and say there was less demand for those workers," Ullrich said. "But I think now ... it actually could be labor supply driving some of that. There are two reasons why you might not add jobs in a month: One is there's no demand for workers, the other is there is demand, but there's not enough supply".
In other words: employers want to hire. They just can't find the workers.
#### The Demographic Cliff
Ullrich points to research she co-authored in May 2026 titled **"The Great Mismatch: How a Shrinking Workforce, AI, and Labor Reallocation Will Define the Next 15 Years"**. The report projects that the U.S. labor force will begin shrinking in 2026—and it attributes this primarily to **accelerating Baby Boomer retirements**, which Ullrich describes as a **"demographic cliff"**.
The numbers are stark:
| Projection | Estimate |
|------------|----------|
| **Labor force decline (2025-2032)** | ~3.7%, or **5.9 million workers** |
| **Partial recovery after 2032** | Yes, but incomplete |
| **Unemployment rate by 2040 (severe AI scenario)** | Could approach **8%** |
The report estimates the labor force will shrink by roughly 3.7%, or about 5.9 million workers, between 2025 and 2032 before partially recovering. Under a more severe AI disruption scenario, the unemployment rate could rise by between 0.5 and 3.5 percentage points by 2040, approaching 8%.
Ullrich told Fortune that when she first ran the numbers, she was stunned: "I was like, 'oh gosh, I don't know'." Around the same time, then-Fed Chair Jerome Powell told reporters the economy was seeing "very, very low, nonexistent, really" growth in the labor force. "I was like, okay, I think we are here with the demographic changes and the share of baby boomers that are leaving the workforce".
#### The Immigration Factor
The demographic cliff is being compounded by **falling immigration**—which matters more than many realize.
Ullrich pointed to BLS data showing that **foreign-born individuals have a labor force participation rate of 66.3%, compared with 61.6% for native-born Americans**. Foreign-born workers tend to be younger and more likely to participate in the workforce.
The Census Bureau projects net immigration will fall to just **321,000 by mid-2026**—a decline of nearly 90% in two years. As Ullrich noted, the Bureau of Labor Statistics' own 10-year projections already point to declining participation, and those projections predate the current immigration restrictions. "I think when their estimates come out this next year, they'll be even more severe declines, because immigrant workers are both younger than native-born workers, but also have higher labor force participation rates".
A separate analysis from ABN AMRO found that of the 0.9 percentage point decline in the aggregate participation rate, **only about 0.2 percentage points can be explained by demographics**. The rest reflects **active withdrawal from the labor force**—with the behavioral decline concentrated in the 55+ age group (likely early retirement) and, more troublingly, among prime-age workers.
#### The Booming Stock Market Effect
Bill Adams, Comerica Bank's chief U.S. economist, pointed to another supply-side factor: **a booming stock market** is making older workers feel comfortable leaving the workforce early.
> "On top of retirement, the stock market has boomed in 2026, and so a lot of older Americans who have 401(k)s and other retirement savings are feeling better able to step away from the workforce," Adams said.
The participation rate for employees 55 and older fell to **37.1% in June, marking a 21-year low**.

### The "Demand Failure" Theory: Workers Are Giving Up
But not everyone buys the supply-side argument.
**Daniel Zhao**, chief economist at Glassdoor, offered a sharply different interpretation. He said the unemployment rate fell for **"the wrong reasons"** —not because more people are getting hired, but because fewer are looking for work.
> "This points to a labor market that's stubbornly refusing to reaccelerate, despite recent optimism," Zhao said in a note.
**Elise Gould**, senior economist at the Economic Policy Institute, echoed this concern. She remarked that while the drop in the unemployment rate might appear positive, it fell for the wrong reasons because **many people exited the labor force, possibly because they did not believe jobs were available for them**.
The data supports this interpretation:
| Indicator | June 2026 Data |
|-----------|----------------|
| **Long-term unemployed (27+ weeks)** | 1.9 million (+286,000 year-over-year) |
| **Share of long-term unemployed** | Remained above 27% |
| **Prime-age participation rate (25-54)** | Fell to **83.3%** |
The share of long-term unemployed—those out of work for at least 27 weeks—remained above 27%. Outside of the COVID-19 pandemic and the subsequent recovery, such a high level of long-term unemployment has not been seen since 2016. Last month, **1.9 million people had been jobless for nearly seven months or longer, an increase of 286,000 compared to a year earlier**.
Perhaps most troubling: the labor force participation rate for prime-working-age individuals (25 to 54) fell to **83.3% in June**. This suggests the overall decline is **not solely due to people aging out of the workforce**.
#### The Discouraged Worker Effect
**Nicole Bechaud**, an economist at ZipRecruiter, told USA TODAY that longtime unemployed people may be so burned out from the job search that they simply give up.
A Catalyst survey earlier this year found that some women left the workforce when companies imposed return-to-office mandates and they needed to care for kids at home. But that doesn't explain why the participation rate for men has also dropped.
ABN AMRO's analysis concluded that the behavioral decline in participation is concentrated in two places: the 55+ age group (most likely explained by early retirement) and prime-age workers. "Some of this may reflect a weak labour market, and some of it may reflect firms using reorganisation, including AI-related restructuring," the report noted.

### The Economywide Impact: A Slower Growth Engine
What is clear, regardless of which theory you believe, is that a sustained decline in the workforce could slow U.S. economic growth.
As Comerica Bank's Bill Adams explained:
> "Economic growth is a combination of the economy generating more for each hour that workers are at the job and more workers working more hours. The first half of that—productivity—is still growing at a good pace in the U.S., but the second half—bringing more workers into the economy—is not contributing as much to growth as it has in the past".
The gap between the establishment survey (which counts jobs) and the household survey (which counts people) has widened dramatically. Since the start of the year, payroll employment has risen by 552,000, while employment in the household survey has fallen by 1,728,000. This gap cannot be easily explained by a rise in multiple jobholders or a shift from self-employment into company payrolls.
**ABN AMRO** warned that the decline in participation is a warning sign. Over the past twenty years, declines of this magnitude have only occurred during COVID and in the second half of 2009, when discouraged workers left the labor force after the Great Recession.

### The Fed Dilemma: Bad News That Looks Like Good News
The declining labor force presents a **serious challenge for the Federal Reserve**.
On one hand, the unemployment rate fell to 4.2%—a number that might typically signal a tightening labor market and inflationary pressures. On the other hand, the decline was driven by people leaving the workforce, not by more hiring.
As San Francisco Fed President Mary Daly said before the jobs data was released, there is "a scenario where the growth just doesn't continue to sustain itself ... or investment slows because people are worried they haven't seen the gains yet". Uncertainty about which risks will need attention—too much inflation or weaker growth—is a reason to wait on any decision about interest rates, Daly said.
**Daniel Zhao** put it bluntly: "The unemployment rate's decline to 4.2% is a case of good news for the wrong reasons. It was driven by people leaving the labor force, not by more hiring".
Fed debate has focused in recent months on the impact of new immigration rules, a discussion sidelined as job growth jumped and on the arrival of new Chairman Kevin Warsh, who has not focused on the issue so far. Yet it could figure importantly into the U.S. growth outlook, and whether the pace of job creation month to month is sustainable.

### What About AI? Not the Main Driver (Yet)
One factor that has received significant attention is artificial intelligence. But according to Ullrich, **AI is not the biggest driver of the current labor force decline**.
> "No matter what we did with AI in our model, demographics were the bigger story," she said.
Apollo Global Management Chief Economist Torsten Sløk went even further, saying in June that there was **"zero evidence" that AI was causing widespread job losses**.
That doesn't mean AI won't matter in the future. The Indeed Hiring Lab report projects that AI will primarily impact industries where younger workers are concentrated—information, finance, and professional business services—potentially driving up unemployment in those sectors. Meanwhile, aging industries like healthcare and education face severe labor shortages that AI cannot easily fill.
But for now, **demographics remain the dominant force**.

### Frequently Asked Questions
**Q: How many people left the U.S. labor force in June 2026?**
A: Approximately **720,000 people left the labor force in June alone**. Over the past year, about **1 million workers have stopped participating**.
**Q: What is the current labor force participation rate?**
A: The labor force participation rate fell to **61.5% in June 2026**. Outside the COVID-19 pandemic, this is the lowest reading in **five decades**.
**Q: Why can't experts agree on the cause?**
A: One camp argues it's a **supply crisis**—there simply aren't enough workers due to Baby Boomer retirements and lower immigration. Another camp argues it's a **demand failure**—workers are discouraged and giving up because they can't find jobs. Both sides have data to support their claims.
**Q: What is the "demographic cliff"?**
A: It refers to the **accelerating retirement of the Baby Boomer generation**. Indeed Hiring Lab projects the labor force will shrink by about **5.9 million workers between 2025 and 2032** due to this demographic shift.
**Q: How does immigration affect the labor force?**
A: Foreign-born workers have a **labor force participation rate of 66.3%**, compared to 61.6% for native-born Americans. They also tend to be younger. With net immigration projected to fall to just 321,000 by mid-2026, this is putting additional downward pressure on the labor force.
**Q: Why is the prime-age participation rate falling?**
A: The prime-age (25-54) participation rate fell to **83.3% in June**. This is particularly concerning because it suggests the decline is not solely due to aging, but also reflects people in their working years dropping out of the labor market.
**Q: What does this mean for the Federal Reserve?**
A: The declining labor force makes it harder for the Fed to read the economy. The unemployment rate fell to 4.2%, but for "the wrong reasons"—people leaving the workforce, not more hiring. This complicates decisions about interest rates.
**Q: Is AI causing these labor force departures?**
A: Most economists say **no—at least not yet**. Laura Ullrich of Indeed Hiring Lab said "demographics were the bigger story" no matter what she did with AI in her models. Apollo's chief economist said there is "zero evidence" that AI is causing widespread job losses.

### Conclusion: A Debate That Matters
The 720,000 people who left the workforce in June aren't just a statistic. They represent real people making real decisions—some retiring early with comfortable 401(k)s, some giving up after months of fruitless job searching, some caring for family members, some struggling with health issues that make work impossible.
The experts may not agree on why Americans are leaving the workforce. But they agree on one thing: **this matters**.
If the supply-side economists are right, the U.S. faces a future of labor shortages, rising wages, and potentially slower growth—but also a workforce that has more bargaining power. If the demand-side economists are right, the country faces a more troubling scenario of discouraged workers, long-term unemployment, and a labor market that isn't delivering for those who want to work.
The Bureau of Labor Statistics projects the labor force participation rate will continue to decline, from 62.6% in 2023 to a projected **61.2% in 2033**. And that projection predates the current immigration restrictions.
The debate over why Americans are leaving the workforce isn't just academic. It will shape policy decisions at the Federal Reserve, influence the 2026 midterm elections, and determine the economic opportunities available to millions of Americans.
As Ullrich put it: "When we first ran the numbers and saw that we were actually predicting the labor force was going to start declining this year, I was like, 'oh gosh, I don't know'".
Now we all have to live with the answer.
