In Denmark, there is no single definition of the age group. Different acts, strategies and institutions target different groups of young people, for instance:

A new reform of preparatory basic education and training (FGU) targets young people under 25 years. FGU may also include young people up until the age of 30 years old. (See section 1.9)

In the area of social affairs, different definitions apply. Sometimes, a young person is defined as being in the 15-17-year age group, and clearly delimited from a child in the 0-14-year age group. At other times, the term “children and young people” is used to define the 0-18-year age group.
