Adolescent reproductive health: What are the lessons learned from the intervention projects

Adolescents aged between 10 to 19 years, are a large and growing segment of the population. At 1.05 billion, this is the biggest-ever generation of young people and their number is increasing rapidly in many countries (UNFPA, 1998a). The population of adolescents will continue to grow because of the growth momentum of age structure and the high fertility rate in the past. Globally, the largest share of adolescents is and will continue to be in Asia, which has 60 per cent of the world population (UNFPA, 1998b).
