WORLD POPULATION TO EXCEED 9 BILLION BY 2050:

Developing Countries to Add 2.3 Billion Inhabitants with 1.1 Billion Aged Over 60 and 1.2 Billion of Working Age

NEW YORK, 11 March (UN Population Division/DESA) – World population is projected to reach 7 billion early in 2012, up from the current 6.8 billion, and surpass 9 billion people by 2050, reveals the 2008 Revision of the official United Nations population estimates and projections
..
Most of the additional 2.3 billion people will enlarge the population of developing countries, which is projected to rise from 5.6 billion in 2009 to 7.9 billion in 2050, and will be distributed among the population aged 15-59 (1.2 billion) and 60 or over (1.1 billion) because the number of children under age 15 in developing countries will decrease.
In contrast, the population of the more developed regions is expected to change minimally, passing from 1.23 billion to 1.28 billion, and would have declined to 1.15 billion were it not for the projected net migration from developing to developed countries, which is projected to average 2.4 million persons annually from 2009 to 2050.
