According to a major study published today, in 2100 on Earth, there could be 8.8 billion people, 2 billion less than projected by the United Nations. The reasons are to be found in the decline of the fertility rate of the population.

In the paper, available on The magazine The Lancet.reads 183 countries out of 195, will fall below the threshold required to maintain the current level of the population: consequently, the dead will not be balanced by births, except for a big influx of immigrants.

Twenty countries (including Japan, Spain, Italy, Thailand, Portugal, South Korea, and Poland) will experience a population decline of halfbut what is surprising is the fact of China, which will increase from 1.4 billion people to 730 million in the space of 80 years.

To triple the size to approximately three billion people will be in sub-saharan Africa, with Nigeria to expand to 800 million compared to the attuai 196, and will be second only to India which will be at 1.1 billion.
