A new study by economists from Harvard and Princeton indicates that 94% of the 10 million new jobs created during the Obama era were temporary positions.

The study shows that the jobs were temporary, contract positions, or part-time “gig” jobs in a variety of fields.

Female workers suffered most heavily in this economy, as work in traditionally feminine fields, like education and medicine, declined during the era.

The research by economists Lawrence Katz of Harvard University and Alan Krueger at Princeton University shows that the proportion of workers throughout the U.S., during the Obama era, who were working in these kinds of temporary jobs, increased from 10.7% of the population to 15.8%.

Krueger, a former chairman of the White House Council of Economic Advisers, was surprised by the finding.
