This volume is the proceedings of an international symposium held in Vienna in June 1994. It reflects several publications on the subject of world population and development, which noted that a reproductive revolution is on the way throughout the world, but particularly in developing countries. The volume comprises the presentations given to the press in Vienna, in a bid to provide journalists with up-to-date reviews of the central issues involved. It summarizes many of the issues which lie at the heart of this reproductive revolution. Family planning programmes and improved health programmes, and improved health and family life education are crucial to the stability of population growth.
