U.S. Labor-Force Shrinkage Signals Trouble Even as Unemployment Remains Low

The unemployment rate remains at 4.4 percent, and on its face that number looks manageable. But the headline figure is increasingly doing the work of concealing a labor market that is contracting in ways that do not show up in the official count — and the structural forces driving that contraction are not temporary.

February’s jobs report from the Bureau of Labor Statistics laid out the picture in plain data: nonfarm payrolls fell by 92,000, marking the third decline in five months. The labor force participation rate dropped to 62.0 percent, its lowest since December 2021. The employment-population ratio fell to 59.3 percent. And yet the unemployment rate barely moved.

The disconnect is not an anomaly. It is a structural feature of how labor force contraction works — and why analysts who look only at unemployment risk missing what is actually happening to the American workforce.

When Workers Leave, the Rate Stays Low

The unemployment rate measures people who are out of work and actively looking for a job. When people stop looking — whether from discouragement, disability, early retirement, or withdrawal from the market for any other reason — they leave the denominator of the unemployment rate entirely. The rate does not rise. It simply becomes less representative of economic reality.

The San Francisco Fed documented this dynamic in detail. Job growth slowed notably from mid-2024 to mid-2025. Such shifts in job growth are usually associated with rising unemployment. The unemployment rate, however, changed relatively little over this period. This steadiness was explained not by a healthy labor market but by a similarly paced slowdown in labor force growth. The Fed’s analysis found underlying fragility on both the supply and demand sides — fragility that the headline unemployment rate obscured.

As of February 2026, 6.0 million people were not in the labor force but reported that they currently wanted a job. These individuals were not counted as unemployed because they were not actively looking for work during the preceding four weeks, or were unavailable to take a job. Among them, 1.6 million were classified as marginally attached to the labor force — people who had searched for work in the prior 12 months but not in the past four weeks.

These millions of Americans exist in the space between employment and unemployment — present enough to reflect genuine labor market weakness, absent enough to leave the headline rate undisturbed.

Three Forces Driving the Shrinkage

Several distinct forces are converging to pull workers out of the labor force simultaneously. None of them are likely to reverse in the short term.

Immigration enforcement. Immigration has been one of the primary engines of US labor force growth for years. The Brookings Institute noted that nearly all growth in the labor force in recent years has stemmed from immigration flows, and reduced entries in 2026 will likely mean negative job creation and slower economic growth. Falling illegal and legal immigration could lead to up to 15.7 million fewer workers by 2035, according to an October study by the National Foundation for American Policy.

Immigration has been falling sharply — from roughly 2.7 million a year at its peak to about 1.3 million, with Census mid-year population assumptions dropping toward roughly 300,000 in 2026. Because immigrants tend to be younger and have higher labor force participation and employment-to-population rates, they contribute disproportionately to aggregate hours worked. Morgan Stanley estimated potential US GDP growth at around 2.3 percent today — with a real risk it slips below two percent if current immigration policy holds.

Federal workforce reductions. The federal government has historically been one of the most stable sources of employment in the country, providing work across every state and region. That stability is now eroding. About 300,000 federal civil service layoffs have been announced by the Trump administration, almost all attributed to the Department of Government Efficiency. By March 2026, 9 percent of the federal workforce had been eliminated.

President Trump’s efforts to pare federal payrolls have seen a slide of 330,000 jobs, or 11 percent of the total federal workforce, since October 2024. Federal government employment fell by 10,000 in February alone. Many workers cut from those rolls have not moved into equivalent private-sector positions. A year after the initial cuts, many displaced federal workers have faced headwinds in a market flooded with skilled labor, with some eventually leaving the Washington region entirely and others taking lower-paying positions in unrelated fields.

Population aging and demographic shift. The 2026 annual Census population control adjustment, incorporated into the February jobs report, revised the composition of the US labor force based on updated migration, birth, and death data. The adjustment increased the number of people not in the labor force by 1.2 million and decreased both the total civilian labor force and the number of employed people by 1.4 million each. It lowered the labor force participation rate by 0.4 percentage point and lowered the employment-population ratio by 0.5 percentage point, while leaving the unemployment rate unchanged.

The demographic shift embedded in those adjustments — fewer prime-age men and more women over 65 — reflects a workforce growing older and participating at lower rates. This is a structural trend that will not reverse.

The AI Question and the Productivity Gap

A labor force that stops growing puts more pressure on productivity to sustain economic output. That is where artificial intelligence enters the analysis — both as a potential solution and as a source of additional displacement pressure.

According to Goldman Sachs Research, “The big story in 2026 in labor will be AI.” The firm noted that if AI-related job losses are pulled forward, that could set the stage for underperformance relative to forecast, potentially leading the Federal Reserve to cut interest rates. Goldman Sachs projects unemployment to inch up to 4.5 percent this year.

The information services sector, hit by AI-related cuts, lost 11,000 jobs in February as part of a 12-month trend in which the sector has averaged a loss of 5,000 jobs per month. Manufacturing lost 12,000 jobs despite tariffs aimed at reshoring production.

The productivity gains from AI that could theoretically offset the shrinking labor supply have not yet materialized at the scale needed. Morgan Stanley estimated underlying trend productivity at roughly 1.8 percent per year, little changed from recent history — meaning there is not yet evidence of an AI-driven productivity boom that would compensate for reduced labor supply.

What the Numbers Are Not Saying

The broader unemployment measure that includes discouraged workers and those working part-time for economic reasons — the U-6 rate — stood at 7.9 percent in February. That figure, nearly double the headline rate, reflects the extent to which the official 4.4 percent understates labor market stress.

The job growth that does exist is narrowly concentrated. The vast majority of gains in 2025 were limited to a single industry — education and health services — with other broad sectors contracting or showing almost no growth. Since LFP rates tend to respond to the cyclical strength of the labor market, declining participation rates suggest a weakening environment for workers even when the headline number appears stable.

A labor market where the unemployment rate holds steady because workers are exiting is not a stable labor market. It is one in transition — shaped by immigration enforcement, government restructuring, demographic aging, and technological displacement arriving simultaneously. The headline rate will eventually register the strain. The structural indicators already are.
