In that study which involved 19,065 people during a 15-year period, rates of infidelity among men were found to have risen from 20% to 28%, and rates for women ranging from 5% to 15%. For example, one study conducted by the University of Washington, Seattle, found slightly, or significantly higher, rates of infidelity for populations under 35, or older than 60.
Results, however, vary year by year, and also by age-group surveyed. Interviews with people in monogamous relationships since 1972 by the GSS have shown that approximately 12% of men and 7% of women admit to having had an extramarital relationship. Īccording to The New York Times, the most consistent data on infidelity comes from the University of Chicago's General Social Survey (GSS). The Janus Report on Sexual Behavior in America also reported that one third of married men and a quarter of women have had an extramarital affair. The Kinsey Reports found that around half of men and a quarter of women studied had committed adultery.
