Example 2: Children and young people in Bielefeld

This map shows how old the people in the various municipal districts are. The yellow circle stands for the proportion of under-three-year-olds, red circles show the number of 3 to 18-year-olds and the green circles indicate the percentage of 18-year-olds and over. So 17 of the 100 people who live in Heepen are aged between 13 and 17 – in the municipal central district there are only 11 of 100! Do you know where the most adults live?
