Teenagers in Kenya and Mexico are more optimistic about their future than those in France and Sweden, according to polling across 15 countries, which found young people in developing nations have more positive outlooks. The survey, conducted by Ipsos ... found young people across all countries were more optimistic than adults, though there was widespread dissatisfaction with politicians. More than nine in 10 teenagers in Kenya, Mexico, China, Nigeria and India reported feeling positive about their future. Their responses contrasted with those of young people in France and Sweden, the most pessimistic of countries surveyed. Dr Alex Awiti, from Aga Khan University, who has researched youth attitudes across east Africa, said young people in the region are optimistic because they know that their voices count. If young people want to mobilise, all the governments in east Africa could be toppled within a matter of days," he said. "What is impressive is young people across east Africa really know what they want." Awiti pointed to the large numbers of youth-led organisations in countries such as Kenya, where under-35s make up about 80% of the population. Young people are still, however, under-represented in politics.
