The number of youth in Today’s world is growing fast. There are 1.8 billions of them, and up to 43 per cent of the world’s population is under the age of 25 as estimated by the United Nations. This rapid increase of this age group in the population is of particular concern to many people working in national and international organizations, namely, the United Nations Population Fund (UNFPA). Realizing that youth of both sexes in all developing countries are key actors influencing the population growth rate, for decades, UNFPA has developed successful advocacy programs to encourage adolescents and youth groups to behave responsibly in their sexual and reproductive activities. These programs have made a lot of differences to the achievement of world sustainable development. Peer-group discussions on prevention of HIV/AIDS and safe-sex help to guarantee success. All through the nineties, UNFPA has organized, with governments and non-governmental organizations, roundtable discussion on various population issues to ensure reproductive rights, to review the effectiveness of sexual and reproductive health programs, to equally involve young women and men in family planning communication and the distribution of condoms and other contraceptives to those in need. At the end of this year, from 4-6 December, UNFPA is a key sponsor of the Global Youth Forum to be held in Bali, Indonesia. It is expected that 900 young women and men will come together to brain storm and further strategize new priorities for action in population, reproductive rights, health and family planning as set out in the ICPD Program of Action, ICPD Beyond 2014. Application is still opened for youth around the world who wish to participate.
