Overall rates of gambling among male college athletes decreased from 66 percent in 2008 to 57 percent in 2012, according to a new National Collegiate Athletic Association study , despite a “noticeable increase” in the number of sports wagering cases investigated by the NCAA. Gambling by female athletes stayed constant, though at the significantly lower rate of 39 percent. However, the survey of 23,000 athletes also found that male athletes are still betting and wagering more on sports than they were in 2004, the first year the NCAA published this study. In 2004, 23.5 percent of male athletes said they bet money on sports in the last year, compared to 25.7 percent in 2012. Rates of gambling for money by men also rise by division; in 2012, from 50 percent in Division I, to 56 percent in Division II, to 65 percent in Division III. And more male athletes wagered something on sports in 2012 -- 18.7 percent in Division I, 25.9 percent in Division II and 31.9 percent in Division III. In 2008, those figures were 17.1, 20.6, and 30.7 percent, respectively.
