The world’s population is projected to reach 8.5 billion by 2030, 9.7 billion by 2050 and exceed 11 billion in 2100, with India expected to surpass China as the most populous around seven years from now and Nigeria overtaking the United States to become the world’s third largest country around 35 years from now, according to a new United Nations report released today.
Moreover, the report reveals that during the 2015-2050 period, half of the world’s population growth is expected to be concentrated in nine countries: India, Nigeria, Pakistan, Democratic Republic of the Congo, Ethiopia, Tanzania, the United States, Indonesia and Uganda.
Wu Hongbo, the UN Under-Secretary-General for Economic and Social Affairs, whose department produced the 2015 Revision of World Population Prospects, the 24th round of official UN population estimates and projections, noted that understanding the demographic changes that are likely to unfold over the coming years “is key to the design and implementation of the new development agenda.”
United Nations Member States are currently in the process of crafting a successor agenda to the landmark Millennium Development Goals (MDGs), which wrap up at the end of this year. A new framework, focused on poverty eradication, social inclusion and preserving the health of the planet, is set to be adopted at a special UN summit, in New York this September.
According to the report’s projections, 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.
