A/CONF.171/13 English Page 38 6.13. Countries should aim to meet the needs and aspirations of youth, particularly in the areas of formal and non-formal education, training, employment opportunities, housing and health, thereby ensuring their integration and participation in all spheres of society, including participation in the political process and preparation for leadership roles. 6.14. Governments should formulate, with the active support of non-governmental organizations and the private sector, training and employment programmes. Primary importance should be given to meeting the basic needs of young people, improving their quality of life, and increasing their contribution to sustainable development. 6.15. Youth should be actively involved in the planning, implementation and evaluation of development activities that have a direct impact on their daily lives. This is especially important with respect to information, education and communication activities and services concerning reproductive and sexual health, including the prevention of early pregnancies, sex education and the prevention of HIV/AIDS and other sexually transmitted diseases. Access to, as well as confidentiality and privacy of, these services must be ensured with the support and guidance of their parents and in line with the Convention on the Rights of the Child. In addition, there is a need for educational programmes in favour of life planning skills, healthy lifestyles and the active discouragement of substance abuse. C. Elderly people Basis for action 6.16. The decline in fertility levels, reinforced by continued declines in mortality levels, is producing fundamental changes in the age structure of the population of most societies, most notably record increases in the proportion and number of elderly persons, including a growing number of very elderly persons. In the more developed regions, approximately one person in every six is at least 60 years old, and this proportion will be close to one person in every four by the year 2025. The situation of developing countries that have experienced very rapid declines in their levels of fertility deserves particular attention. In most societies, women, because they live longer than men, constitute the majority of the elderly population and, in many countries, elderly poor women are especially vulnerable. The steady increase of older age groups in national populations, both in absolute numbers and in relation to the working-age population, has significant implications for a majority of countries, particularly with regard to the future viability of existing formal and informal modalities for assistance to elderly people. The economic and social impact of this "ageing of populations" is both an opportunity and a challenge to all societies. Many countries are currently re-examining their policies in the light of the principle that elderly people constitute a valuable and important component of a society’s human resources. They are also seeking to identify how best to assist elderly people with long-term support needs. /...
