The world's food producers have a big job ahead of them in the next century. New data from the United Nations (UN) project a world population of 11 billion by 2100. The current world population is 7.2 billion.
The UN's "World Population Prospects" doesn't stop there. Depending on statistical models, the number of people inhabiting our planet could top 16.6 billion or be as low 6.8 billion.
In either case, the world's poorest regions will likely see a dramatic population boon. In Africa alone, the population is forecast to increase nearly four-fold by 2100 to 4.2 billion. India is expected to become the world's largest country, passing China around 2028, when both countries will have populations of 1.45 billion. After that, India's population will continue to grow and China's is expected to start decreasing.
The report's figures are based on a comprehensive review of available demographic data from 233 countries and areas around the world, including the 2010 U.S. population censuses.
