More than half of recent four-year college graduates, 52 percent, are underemployed a year after they graduate, according to a new report from Strada Institute for the Future of Work and the Burning Glass Institute. A decade after graduation, 45 percent of them still don’t hold a job that requires a four-year degree. Those stark data points were highlighted in a report released today called “Talent Disrupted.” The report outlines employment outcomes for recent bachelor’s degree earners and explores the factors that contribute to their short- and long-term underemployment. It drew on federal data sources, job ads and online résumé and career profiles for more than 60 million workers.
