Currently, the global population is roughly 7.6 billion, with the United Nations (UN) estimating it to grow to over 11 billion by 2100. In its report, UN World Population Prospects, the UN details where the growth will occur and which regions will prosper. The UN has found that world population growth is actually growing less slowly than it has in the past, thus hindering accurate population projections. Yet, the UN has historically been fairly good with its estimates and projections, taking regional characteristics into account.
The UN anticipates that over half of all global growth between 2017 and 2050 will occur in Africa alone. It also projects that growth in Asia will continue, but at a slower pace heading towards 2100. Download August 2017
