Signal World population milestones from 2.6 billion in 1950 to 7 billion in 2011
Summary
The Megatrends 2040 report traces the milestones of world population growth. In 1950, five years after the United Nations was founded, the global population was estimated at about 2.6 billion. The total passed 5 billion in 1987 and then 6 billion by 1999. The 7 billion mark was reached in October 2011, an event marked by a global campaign called 7 billion actions. The report attributes this dramatic growth largely to more people surviving to reproductive age, accompanied by changing fertility, rising urbanisation and accelerating migration.
