Before merging with FIG in 1999, the International Federation of Sports Acrobatics (IFSA) organized and promoted World Junior Championships in acrobatic gymnastics from 1989 to 1999.^[2] As of 2019, FIG has organized junior world championships in artistic and rhythmic gymnastics.^[3]

Currently, FIG organizes periodical World Age Group competitions in aerobic gymnastics, acrobatic gymnastics and trampoline. The former governing body for trampoline, the International Trampoline Federation (FIT), incorporated into the FIG in 1998, also organized World Age Groups competitions from 1973 to 1996.^[4] These competitions, however, are not considered world championships.

Since 1998, the championships are held alongside the Trampoline Gymnastics World Championships, often a week later and in the same venue. From 1990 to 1996, the junior championships were in the same country as the Trampoline Gymnastics World Championships, but in a different city. The earlier championships, from 1973 to 1988, had separate hosts, unrelated to the Trampoline Gymnastics World Championships.
