NEW YORK (CNNMoney) - The drop in the unemployment rate in August isn't particularly good news for the economy - it's driven mostly by nearly 400,000 people dropping out of the labor force, rather than more people finding jobs.
But those dropping out aren't so much the discouraged 30-, 40- or 50-year olds. In fact, the Labor Department said there was a modest decline in the overall number of discouraged job seekers.
The drop is because so many young adults, aged 16 to 24, are no longer looking for work.
There were 453,000 fewer young adults with jobs in August than in July. But despite that plunge, only 27,000 more young people were looking for new jobs. Most apparently stopped looking and left the labor force. And those numbers take into account seasonal factors such as younger workers returning to school.
As a result, the percentage of young people who are counted in the labor force fell to its lowest level since 1955.
The unemployment rate for young adults rose to 16.8% from 16.4% in July.
"I don't think they're more lazy. It's that there are less opportunities for them," said Heidi Shierholz, labor economist, at the Economic Policy Institute, a liberal think tank. "They have it rough."
