The world population is now nearly 7.6 billion, up from 7.4 billion in 2015, spurred by the relatively high levels of fertility in developing countries – despite an overall drop in the number of children people have around the globe – the United Nations today reported.
The concentration of global population growth is in the poorest countries, according to World Population Prospects: The 2017 Revision, presenting a challenge as the international community seeks to implement the 2030 Sustainable Development Agenda, which seeks to end poverty and preserve the planet.
“With roughly 83 million people being added to the world's population every year, the upward trend in population size is expected to continue, even assuming that fertility levels will continue to decline,” said the report's authors at the UN Department of Economic and Social Affairs.
At this rate, the world population is expected to reach 8.6 billion in 2030, 9.8 billion in 2050 and surpass 11.2 billion in 2100.
The growth is expected to come, in part, from the 47 least developed countries, where the fertility rate is around 4.3 births per woman, and whose population is expected to reach 1.9 billion people in 2050 from the current estimate of one billion.
In addition, the populations in 26 African countries are likely to “at least double” by 2050, according to the report.
