• Twenty-five states are ending their participation in federal unemployment programs before their expiration Sept. 6. Maryland's announcement Tuesday was the most recent.
• All but two Republican-led states are ending the benefits early. Their decisions affect at least 3.7 million people, according to a CNBC analysis.
• Those affected will lose a $300 weekly supplement. In most states, benefits for the self-employed and long-term unemployed will also end entirely.

Around 3.7 million Americans will be affected by states' early withdrawal from federal unemployment programs, according to a CNBC analysis of Labor Department data.

In the past month, 25 states have announced plans to end pandemic-era benefits ahead of their formal expiration Sept. 6. Some states are ending the aid as early as June 12.  

Maryland on Tuesday became the latest state to announce its withdrawal, effective July 3. The other 24 states are Alabama, Alaska, Arizona, Arkansas, Florida, Georgia, Idaho, Indiana, Iowa, Mississippi, Missouri, Montana, Nebraska, New Hampshire, North Dakota, Ohio, Oklahoma, South Carolina, South Dakota, Tennessee, Texas, Utah, West Virginia and Wyoming.

The affected workers are poised to lose a $300 weekly supplement to unemployment benefits. Most states are also ending benefits entirely for the self-employed, gig workers and the long-term unemployed.

The states — all of which are led by Republican governors — claim enhanced unemployment benefits are causing laid-off workers to stay home instead of looking for jobs.

That dynamic has made it tough for businesses to fill record job openings, they said.

"While these federal programs provided important temporary relief, vaccines and jobs are now in good supply," Maryland Gov. Larry Hogan said Tuesday. "And we have a critical problem where businesses across our state are trying to hire more people, but many are facing severe worker shortages."

The programs in question have been in place since lawmakers passed the CARES Act in March 2020. The American Rescue Plan extended them through Labor Day.

Economists believe enhanced jobless aid may be playing at least a small role in hiring challenges for businesses. However, the magnitude is impossible to quantify and other factors are likely more substantial, they said.

The cuts are "tied to politics, not economics," according to a JPMorgan research note published last week.

All but two Republican-led states — Massachusetts and Vermont — have said they'll end the federally funded benefits early. (Massachusetts Gov. Charlie Baker recently pledged to keep the benefits in place.)

CNBC's analysis of affected workers is likely a slight undercount since the Labor Department doesn't report data for all recipients in Florida and Georgia.

The tally would be roughly 3.9 million people if all recipients in those states were included, according to an estimate from Andrew Stettner, a senior fellow at progressive think tank The Century Foundation.

Other factors

States' decisions to withdraw largely come after the April jobs report fell short of expectations. Payrolls grew by 266,000, far lower than the 1 million predicted. Meanwhile, job openings hit a record the month prior.

"The disappointing jobs report makes it clear that paying people not to work is dampening what should be a stronger jobs market," U.S. Chamber of Commerce chief policy officer Neil Bradley said.

But such criticism overlooks a host of other temporary, pandemic-related factors that are also contributing to labor-market dynamics, according to economists and worker advocates.

There remain 8 million fewer jobs than before the pandemic, according to the Bureau of Labor Statistics.

Child care may be an obstacle for working parents in areas where schools and daycare centers haven't fully reopened, according to economists. Many older workers retired early and may not return to the labor force.

People may still be wary of returning to work, especially at in-person jobs, due to pandemic health risks. Data from the Centers for Disease Control and Prevention show that 52% of U.S. adults are fully vaccinated. (However, the share is lower for working-age adults — the data is skewed upward by seniors who may be out of the workforce but have been vaccinated at higher rates.)

Businesses have been more likely to classify recent job posts as "urgent" or "immediate" (potential signs of difficulty finding workers) when that work was in-person rather than remote, according to an analysis published Monday by Indeed, a job site.

"It's bad news," Stettner said of states' withdrawal. "It's like a classic example of blaming the victim.

"It's a crazy policy response to a situation that's obviously a lot more complex than that," he added.

Critics also argue the benefit cutoff may reduce demand for goods and services, potentially undercutting the need to hire.

Local economies would lose more than $12 billion due to states' early withdrawal, according to an analysis published Tuesday by Rep. Don Beyer, D-Va., chairman of the Joint Economic Committee.

Correction: Maryland's announcement that it will be ending enhanced unemployment benefits was made Tuesday. A previous version misstated the day in one reference.
