The world will have about 9.2 billion people by 2050, with those aged over 60 surpassing under-15s for the first time, the United Nations said in a report.
The global population will increase by 2.52 billion from today's 6.67 billion over the next 43 years, an increase equivalent to the entire population in 1950, the UN Population Division said yesterday in a statement and accompanying data tables posted on its Web site. The UN's projections take into account new census data from national censuses and surveys conducted around the world. By 2045, the number of people over the age of 60 will likely surpass the total of children under 15, the division said. In 2050, those aged 60 and above are likely to number more than 2 billion, with 1.8 billion under-15s, the data show. „As a result of declining fertility and increasing longevity, the populations of more and more countries are aging rapidly,” the division said. The median average age of a person in 2050 will be 38.1 years, up from 28 in 2005 and 23.9 in 1975.
India, with 1.658 billion people by 2050, will overtake China as the world's most populous nation, the predictions show. The figures show more than 99% of the rise is expected in developing nations, with the population of industrialized countries remaining largely static. The projected population in developed countries by 2050 „would have declined, were it not for the projected net migration from developing to developed countries, which is expected to average 2.3 million persons annually,” the division said in its statement. The projection shows that the world's population will have more then tripled in just a century, to 9.2 billion in 2050 from 2.5 billion in 1950. The population of developed countries will probably rise to 1.245 billion in 2050 from 1.223 billion now, while the number of inhabitants of developing nations will surge to 7.946 billion from 5.448 billion, the UN said.
