One large survey of university counseling centers found that only 37% of students who came through their doors in 2009 and prior years had complained about problems with anxiety—roughly on a par with the two other leading concerns, depression and relationships.37 But beginning in 2010, the percentage of students with anxiety complaints began to increase. It reached 46% in 2013 and continued climbing to 51% in 2016. It is now by far the leading problem for which college students seek treatment.
