Whether American college students are in some sort of new era of hook-ups has been the subject of much media speculation and criticism.  Research being released today  by the University of Portland at the annual meeting of the American Sociological Association suggests that while there is plenty of sex in college, it's not remotely new or even hitting record levels. Martin Monto, a sociology professor, and Anna Carey, a recent graduate, compared data from a national survey about sex on campus from 1988-1996 and from 2002-10. In the recent time period, being called a hook-up era by some, only 59 percent of students report having sex at least once a week, compared to 65 percent in the earlier period. On other measures as well, there are not signs of a more hyper-sexual environment today than in earlier periods.
