Most large public universities in the United States do not keep records of how many students have taken their own lives. Yet many American colleges and universities are making investments in suicide prevention. And the demand for mental health services is rising. These are just a few of the findings of a report by the Associated Press, or AP, news agency. The report was released in early January. The Associated Press asked the 100 largest U.S. public universities for yearly numbers on student suicides. It found that only 46 currently keep such statistics.
