26. The growing strength of the non-governmental sector, particularly women’s organizations and feminist groups, has become a driving force for change. Non-governmental organizations have played an important advocacy role in advancing legislation or mechanisms to ensure the promotion of women. They have also become catalysts for new approaches to development. Many Governments have increasingly recognized the important role that non-governmental organizations play and the importance of working with them for progress. Yet, in some countries, Governments continue to restrict the ability of non-governmental organizations to operate freely. Women, through non-governmental organizations, have participated in and strongly influenced community, national, regional and global forums and international debates. 27. Since 1975, knowledge of the status of women and men, respectively, has increased and is contributing to further actions aimed at promoting equality between women and men. In several countries, there have been important changes in the relationships between women and men, especially where there have been major advances in education for women and significant increases in their participation in the paid labour force. The boundaries of the gender division of labour between productive and reproductive roles are gradually being crossed as women have started to enter formerly male-dominated areas of work and men have started to accept greater responsibility for domestic tasks, including child care. However, changes in women’s roles have been greater and much more rapid than changes in men’s roles. In many countries, the differences between women’s and men’s achievements and activities are still not recognized as the consequences of socially constructed gender roles rather than immutable biological differences. 28. Moreover, 10 years after the Nairobi Conference, equality between women and men has still not been achieved. On average, women represent a mere 10 per cent of all elected legislators world wide and in most national and international administrative structures, both public and private, they remain underrepresented. The United Nations is no exception. Fifty years after its creation, the United Nations is continuing to deny itself the benefits of women’s leadership by their underrepresentation at decision-making levels within the Secretariat and the specialized agencies. 29. Women play a critical role in the family. The family is the basic unit of society and as such should be strengthened. It is entitled to receive comprehensive protection and support. In different cultural, political and social systems, various forms of the family exist. The rights, capabilities and responsibilities of family members must be respected. Women make a great contribution to the welfare of the family and to the development of society, which is still not recognized or considered in its full importance. The social significance of maternity, motherhood and the role of parents in the family and in the upbringing of children should be acknowledged. The upbringing of children requires shared responsibility of parents, women and men and society as a whole. Maternity, motherhood, parenting and the role of women in procreation must not be a basis for discrimination nor restrict the full participation of women in society. Recognition should also be given to the important role often played by women in many countries in caring for other members of their family. 30. While the rate of growth of world population is on the decline, world population is at an all-time high in absolute numbers, with current increments approaching 86 million persons annually. Two other major demographic trends have had profound repercussions on the dependency ratio within families. In many developing countries, 45 to 50 per cent of the population is less than 15 years old, while in industrialized nations both the number and proportion of -12-
