What Is the percentage of incoming college students reported not drinking at all in past year?

There's no single, universally agreed-upon percentage of incoming college students who report not drinking at all in the past year. The percentage varies depending on the survey used, the year the survey was conducted, the specific college or university sampled, and the definition of "incoming student" (e.g., freshman only, or including transfers).

Studies from organizations like the National Institute on Alcohol Abuse and Alcoholism (NIAAA) and the Centers for Disease Control and Prevention (CDC) regularly collect data on college student drinking habits, but their findings show a range of percentages. You'd need to specify the source and year of the study to get a precise answer. Generally, the percentage of abstainers is consistently lower than the percentage of drinkers.
