The Youth Health Index uses data from the Kansas Communities That Care (KCTC) youth survey that has been administered annually throughout the State since 1994. The survey tracks teen use of harmful substances such as alcohol, tobacco and other drugs. In addition, the survey provides a baseline for teen participation in, perception of, and attitudes toward both prosocial and antisocial behavior at the peer, school, family and community levels. The Index encompasses 18 questions specifically chosen in the survey that particularly focus around topics like health, safety, and perception of the city.
