As the first social generation to have grown up with access to the Internet and portable digital technology from a young age, members of Generation Z have been dubbed "digital natives", even though they are not necessarily digitally literate. Moreover, the negative effects of screen time are most pronounced on adolescents compared to younger children. Compared to previous generations, members of Generation Z in some developed nations tend to be well-behaved, abstemious, and risk-averse. They tend to live more slowly than their predecessors when they were their age, have lower rates of teenage pregnancies, and consume alcohol less often, but not necessarily addictive drugs. Teenagers nowadays seem more concerned with academic performance and job prospects, and are better at delaying gratification than their counterparts from the 1960s, despite concerns to the contrary. On the other hand, sexting among adolescents has grown in prevalence though the consequences of this remain poorly understood. Meanwhile, youth subcultures have been quieter, though not necessarily dead.
