Earth Population 2050 Projection Projections. Extending the un’s probabilistic population models, the paper, published in the international journal of forecasting, found that our population size in 2300 will likely be between 2 and 26 billion people, with a median. The current world population of 7.6 billion is expected to reach 8.6 billion in 2030, 9.8 billion in 2050 and 11.2 billion in 2100, according to a new united nations report being launched.

The global population is expected to increase by 38%, from 6.9 billion in 2010 to 9.6 billion in 2050. According to these projections, by 2050 about 155 out of 204 countries will not have enough births to ensure a stable global population count.
