That’s almost 15 percent of those aged 16 to 24 who have neither desk nor job, according to The Opportunity Nation coalition, which wrote the report.

Other studies have shown that idle young adults are missing out on a window to build skills they will need later in life or use the knowledge they acquired in college. Without those experiences, they are less likely to command higher salaries and more likely to be an economic drain on their communities.

“This is not a group that we can write off. They just need a chance,” said Mark Edwards, executive director of the coalition of businesses, advocacy groups, policy wonks and nonprofit organizations dedicated to increasing economic mobility. “The tendency is to see them as lost souls and see them as unsavable. They are not.”

But changing the dynamic is not going to be easy.
