More than 17,000 children aged 8 years old in 16 countries in four continents were asked about their experiences and views about their lives. Research of this kind with this age group is very unusual and this is the most wide-ranging and diverse study of its kind ever conducted internationally on children’s lives from their own perspectives. The second report from the Children’s Worlds study, published today, shows important results that can be used to improve children’s lives around the world.
