Teen Sexual Behaviour: The YRBS
Captions available
The idea
The Youth Risk Behavior Survey anonymously samples US high-school students every two years; in twenty twenty-one, thirty percent had ever had sexual intercourse.
In practice
Twenty-one percent currently sexually active, with girls and boys at nearly identical rates.
Where people slip
The survey leaves "intercourse" undefined, and teens interpret it differently, which complicates the figures.
