Employers reported the stimulus package created or retained 640,329 jobs nationwide through the end of September, according to a U.S. Congressional Budget Office report released Tuesday.
More than half of the jobs created were in health care.
The numbers came from jobs reports that contractors must file with the federal government when receiving more than $25,000 from the American Recovery and Reinvestment Act.
The CBO report said the true effects of the stimulus package are hard to gauge. It is impossible to say how many jobs would have been created or retained if the act had never been approved.
The numbers are also faulty, according to the report, because they show only jobs reported by prime contractors and some, but not all, subcontractors on stimulus projects.
