College enrollment is dropping. Bad sign?

For years, America’s college campuses swelled with more and more students. But enrollment peaked in 2010 at just over 21 million students. Attendance has dropped every year since.

By the fall of 2014 — the most recent year government data is available — there were 812,069 fewer students walking around college campuses.

Some say not to worry, the drop is happening because the economy is improving. More people are going back to work instead of signing up for additional degrees.

“Historically, as the economy improves and Americans get back to work, college enrollment declines,” says U.S. Under Secretary of Education Ted Mitchell.
