The NCAA conducted its survey to 'better understand what student-athletes are experiencing on their campuses and among their peers' in order to 'best help them deal with the potentially disruptive dynamic of legal sports betting,' President Charlie Baker said in a statement Wednesday. Among sports bettors pursuing a college degree, a little over 40% have placed wagers on their own school's team, the NCAA said. Nearly 70% of college students living on campus are bettors. The statistic is troubling, the NCAA said, because in many states - including Arizona, Iowa, Louisiana and Massachusetts - gamblers must be at least 21 to place a bet. The national survey of 18- to 22-year-olds found that 58% of respondents have placed at least one wager this year. That's according to a study from the NCAA.

Teenagers are placing sports bets online even though some of them reside in states where sports gambling is prohibited under the age of 21, or illegal altogether.
