American adults, on average, are having sex about nine fewer times per year in the 2010s compared to adults in the late 1990s, according to a team of scholars led by the psychologist Jean Twenge. That’s a 14 percent decline in sexual frequency. Likewise, the share of adults who reported having sex “not at all” in the past year rose from 18 percent in the late 1990s to 22 percent from 2014 to 2016, according to our analysis of the General Social Survey. (The GSS, which is fielded every two years and is directed by the University of Chicago, is a large, nationally representative and federally funded survey of American adults covering a range of attitudes and behaviors.)
