Males were more likely than females to engage in all levels of binge drinking. Differences by race/ethnicity were: White students were more likely to engage in all levels of binge drinking than Black students and more likely to report 5+ binge and 10+ extreme binge drinking than students of most other race/ethnicities. White students and Hispanic students did not differ. The association between parental education and binge drinking differed across the thresholds of binge drinking. Students whose parents were college-educated had greater odds of engaging in 5+ binge drinking and lower odds of engaging in 15+ extreme binge drinking, with no difference in 10+ extreme binge drinking rates, compared to students whose parents were not college-educated. There were few differences by region or population density, although students in the Northeast and West were less likely to engage in 15+ extreme binge drinking than students in the South. Compared to students in large MSA areas, students in non-MSA (ie, more rural) areas had greater odds of engaging in 15+ extreme binge drinking. High school grades and college plans did not predict
