Key Findings and Advance Tables
United Nations, Department of Economic and Social Affairs (DESA), Population Division, June 2013
The 2012 Revision of World Population Prospects represents the latest global demographic estimates and projections. According to this revision the world population of 7.2 billion in mid-2013 is projected to increase by almost one billion people within the next twelve years, reaching 8.1 billion in 2025, and to further increase to 9.6 billion in 2050 and 10.9 billion by 2100. Small differences in the trajectory of fertility during the next decades will have major consequences for population size, structure, and distribution in the long run.
