Changing population age structures and sustainable development: Achievements, challenges, opportunities
At its 50th session in April 2017, the Commission on Population and Development will consider a universal feature of recent population trends: changing population age structures. Gradual shifts in the age distribution of a population present both challenges and opportunities for sustainable development. The world’s population has undergone profound changes as mortality and fertility levels have decreased around the world. This pair of changes, known together as the demographic transition, leads initially to rapid growth and a younger population, driven by an early reduction in child mortality.
