Notice that percentages decrease consistently over time.Percentage of 12th graders who had ever gone on a date: Percent of high-schoolers who had ever had sex The research on the percent of high-schoolers who had ever had sex was based on data collected in surveys, starting in 1991.In the three time periods between 19 (1976-1979; 1980-1984; and 1985-1989), the share of 12th graders who had ever gone on a date was either 86 percent or 87 percent.

It is the way scholars have often thought about young adults — sure, they may be slower than they were in the past to get around to marrying or having kids, but give them time, and they’ll get there. For example, a Pew Research Center report estimated that by the time today’s young adults reach the age of 50, about 25 percent of them will have been single their entire lives.

Think about that — a cohort of 50-year-olds in which 1 out of 4 has never been married.

Dating and sex were only two of the behaviors that Twenge and Park analyzed in their study of U. They use their results to make the case for a new and slower life strategy, compared to a faster strategy of the past.

Teens can move more slowly toward adulthood, Twenge and Park argue, because, on average, they are in “resource-rich environments.” For example, parents have fewer children than they did in the past, and so they can invest more in each one.

Dating violence can be physical, emotional or sexual.

Dating abuse can occur between any two teens in an intimate relationship.

The same number (55 percent) said that having children was “not important” to becoming an adult.

Other experiences, such as completing formal schooling and having full-time employment, mattered more.

A quarter century of data on teenage sex (1990-2016) indicate that the percentage of students in the 9th through 12th grades who have ever had sex has also reached a low point.

The research report, by Jean Twenge of San Diego State University, and Heejung Park of Bryn Mawr College, was just released by the journal Child Development.

Lots of times, teens do not even realize that their relationship is abusive.
