UN: World population to hit 9.8bn by 2050

The world s total population is expected to hit 9.8 billion by 2050 despite universal lower fertility rates the UN said in a report.

The world population is now at least 7.6 billion up from 7.4 billion last year 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 report World Population Prospects: The 2017 Revision revealed on Wednesday.

The concentration of global population growth is in the poorest countries presenting a challenge as the world seeks to implement the 2030 Sustainable Development Agenda which is aimed to end poverty and preserve the planet according to the report.

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 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 reports Xinhua news agency.

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 1 billion.

In addition the birth rates in African countries are likely to at least double by 2050 said the report.

That trend comes despite lower fertility rates in nearly all regions of the world including in Africa where rates fell from 5.1 births per woman up to 2005 to 4.7 births in the five years following.

In contrast the birth rates in Europe are up to 1.6 births per woman up from 1.4 births in 2000-2005.

The lower fertility rates are resulting in an ageing population with the number of people aged 60 or over expected to more than double by 2050 and triple by 2100 from the current 962 million to 3.1 billion.

Africa which has the youngest age distribution of any region is projected to experience a rapid ageing of its population the report noted.

In terms of other population trends depicted in the report the population of India which currently ranks as the second most populous country with 1.3 billion inhabitants will surpass China s 1.4 billion citizens by 2024.

By 2050 the third most populous country will be Nigeria which currently ranks seventh and which is poised to replace the US.
