The current survey
The pilot survey was reviewed and learning from this review was used to refine the questionnaires, leading to three versions of the questionnaire for different age groups that have been used in the current wave of the survey.
The current wave of the project is funded by the Jacobs Foundation and consists of a survey of children aged 8 to 12 which has so far been completed by just over 53,000 children in 15 countries. The survey is currently under way in a further five countries. A complete listing of the countries is shown in the table on the next page. In some countries, the survey covered the whole country while in other countries the survey covered a specific region. Further details are provided in Chapter 2, which also provides a description of survey methodology.
