The questionnaires used for the Young Lives survey are developed specifically for each survey round, to capture the changes in household circumstances and the children's lives as they grow up. In each case, a core questionnaire is produced and used across all four study countries, with specific questions and sections added by each country team to capture information of particular relevance in that country.
