World to have seven billion people by 2012March 12th, 2009 - 12:07 am ICT by IANS
New York, March 11 (DPA) The world population is expected to reach seven billion by 2012, from the current 6.8 billion, with the additional population increase coming mostly in developing countries, the UN said Wednesday.
By 2050, the world population is projected to reach over nine billion people based on an annual average gain of 78 million people. Most governments depend on UN studies in world population to map socioeconomic policy.
Most of the 2.2 billion additional people by 2012 will be in developing countries, where people of working age and those aged 60 and over are expected to increase. Developing countries now make up 5.6 billion people of the world population of 6.8 billion.
The current population in developing countries is still young, with children under 15 accounting for 29 percent of the population and those aged 15 to 24 accounting for 19 percent of total population. There are now 1.7 billion children and 1.1 billion young people in those countries.
“In fact, the numbers of children and young people in the less developed regions are at an all-time high, posing a major challenge for their countries, which are faced with the necessity of providing education or employment to large numbers of children and youth even as the current economic and financial crisis unfolds,” the UN said.
The number of people aged 60 and over is expected to grow globally from 739 million in 2009 to 2 billion by 2050, with the majority of them - up to 79 percent - living in developing nations by 2050.
The picture is different in rich regions, however. The number of children under 15 will remain close to 200 million and youths 15 to 24 will decrease from the current 160 million to 134 million by 2050. Most developed countries have had below replacement fertility - below 2.1 children per woman - in the past two to three decades, the UN said.
The UN said world population growth would continue in the most populous countries. Nine countries in the world will account for half of the projected world population growth during the period from 2010 to 2050: India, Pakistan, Nigeria, the United States, the Democratic Republic of Congo, Tanzania, China and Bangladesh.
