Generation Z (often shortened to Gen Z), colloquially known as Zoomers, is the demographic cohort succeeding Millennials and preceding Generation Alpha. Researchers and popular media use the mid-to-late 1990s as starting birth years and the early 2010s as ending birth years. Most members of Generation Z are the children of Generation X or older Millennials.

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, even if not necessarily digitally literate, have been dubbed "digital natives". Moreover, the negative effects of screen time are most pronounced in adolescents, as compared to younger children.Compared to previous generations, members of Generation Z tend to live more slowly than their predecessors when they were their age, have lower rates of teenage pregnancies, and consume alcohol (but not necessarily other psychoactive drugs) less often. Generation Z teenagers are more concerned than older generations with academic performance and job prospects, and are better at delaying gratification than their counterparts from the 1960s, despite concerns to the contrary. Sexting among adolescents has grown in prevalence; the consequences of this remain poorly understood. Youth subcultures have not disappeared, but they have been quieter. Nostalgia is a major theme of youth culture in the 2010s and 2020s.

Globally, there is evidence that the average age of pubertal onset among girls has decreased considerably compared to the 20th century, with implications for their welfare and their future. Furthermore, the prevalence of allergies among adolescents and young adults in Generation Z is greater than the general population; there is greater awareness and diagnosis of mental health conditions, and sleep deprivation is more frequently reported.In many countries, Gen Z youth are more likely to be diagnosed with intellectual disabilities and psychiatric disorders than older generations.

Around the world, members of Generation Z are spending more time on electronic devices and less time reading books than before, with implications for their attention spans, vocabulary, academic performance, and future economic contributions. In Asia, educators in the 2000s and 2010s typically sought out and nourished top students; in Western Europe and the United States, the emphasis was on poor performers. Furthermore, East Asian and Singaporean students consistently earned the top spots in international standardized tests in the 2010s.
