WASHINGTON (AP) â¿¿ In a story Sept. 7 about unemployment, The Associated Press incorrectly spelled Michael Mangum's name in the penultimate paragraph. A corrected version of the story is below: The job market Fed faces: healing but still ailing Job market's vital signs: Unemployment is down, but many US employers remain reluctant to hire By PAUL WISEMAN AP Economics Writer WASHINGTON (AP) â¿¿ Just how sturdy is the U.S. job market? That's the key question the Federal Reserve will face when it decides later this month whether to reduce its economic stimulus. The answer depends on where you look. The economy has added jobs for 35 straight months. Unemployment has reached a 4Â½-year low of 7.3 percent. Layoffs are dwindling. Yet other barometers of the job market point to chronic weakness: The pace of hiring remains tepid. Job growth is concentrated in lower-paying industries. The economy is 1.9 million jobs shy of its pre-recession level â¿¿ and that's not counting the additional jobs needed to meet population growth. Nearly 4.3 million people have been unemployed at least six months. What's more, employers have little incentive to raise pay. Many unhappy employees have nowhere else to go. Still, when it meets Sept. 17-18, the Fed is expected to reduce its $85 billion a month in bond purchases by perhaps $10 billion. Its purchases have helped keep home-loan and other borrowing rates low to try to encourage consumers and businesses to borrow and spend more. Here's a look at the job market's vital signs as the Fed's decision nears: UNEMPLOYMENT The unemployment rate slid in August to 7.3 percent, its lowest level since December 2008. Unemployment had peaked in October 2009 at 10 percent and has since fallen more or less steadily. Since then, the number of people who say they have jobs has risen by 5.7 million. And the number of those who say they're unemployed has dropped by nearly 4.1 million.
