 Sampling of selected people


3200 people were randomly selected and subdivided into 64 groups throughout Belgium. Each group contains 50 people: children, adolescents and adults.

The number of groups that were selected in each province is proportional to the population size of this province.

For example: Brussels-Capital counts 1.161.6547 inhabitants, while the province of Luxembroug count 278.167 inhabitants. So, 7 groups of 50 persons were selected in the Brussels-Capital region and 2 groups of 50 persons in the province of Luxembourg.

In total 500 little children, 500 children, 1000 adolescents, 600 young adults and 600 adults will be interviewed.
