Rape has significantly decreased over the past 40 years. You know who to thank.
The most likely explanation involves impressive generational developments. In 1970, women made up one-third of all college students (versus 57% today), earned about one-fourth of all young-adult income (versus nearly half today) and made up small fractions of doctors and lawyers (versus majorities of new entrants into these fields now). Women’s rapidly rising status and economic independence in the larger society fostered new attitudes and laws that rejected violence against women.
That younger people growing up in this environment of greater gender equality should show the biggest decreases in rape, while older generations lag behind, is consistent with this explanation. The youngest teenagers (presumably those raised with the most modern attitudes) show the biggest declines of all. Over the last 30 years, rape arrest rates have fallen by 80% among Californians under age 15, much larger than the 25% drop among residents age 40 and older.
Ultimately, however, sexual violence remains a serious danger. That is the best reason for rigorously scrutinizing its real patterns and trends (rather than taking tiresome potshots at “young people” and “popular culture”) to learn how to further reduce it.
