The current world population of 7.3 billion is expected to reach 8.5 billion by 2030, 9.7 billion in 2050 and 11.2 billion in 2100, according to a new UN DESA report, World Population Prospects: The 2015 Revision, launched today.
Understanding the demographic changes that are likely to unfold over the coming years, as well as the challenges and opportunities that they present for achieving sustainable development, is key to the design and implementation of the new development agenda, said Wu Hongbo, UN Under-Secretary-General for Economic and Social Affairs.
Most of the projected increase in the worlds population can be attributed to a short list of high-fertility countries, mainly in Africa, or countries with already large populations. During 2015-2050, half of the worlds population growth is expected to be concentrated in nine countries: India, Nigeria, Pakistan, Democratic Republic of the Congo, Ethiopia, United Republic of Tanzania, United States of America (USA), Indonesia and Uganda, listed according to the size of their contribution to the total growth.
