“Global population numbers are on track to reach 7 billion in 2011, just 12 years after reaching 6 billion in 1999. Virtually all of the growth is in developing countries. And the growth of the world’s youth population (ages 15 to 24) is shifting into the poorest of those countries. The Population Reference Bureau’s 2009 World Population Data Sheet and its summary report, to be released on Aug. 12, offer detailed information about country, regional, and global population patterns.”
