There are currently about 7.8 billion people living in the world. That number is expected to grow in the next few decades and reach 9.7 billion in 2064, before falling to 8.8 billion in 2100.
These are the new data from the latest research published in the magazine "The Lancet", and reports Sarajevo "Dnevni Avaz".
"The last time the global population declined was in the mid-14th century due to the plague. If our forecast is correct, this will now be the first time the world population has shrunk due to declining fertility, unlike in the past when epidemics or famine were the cause.
In as many as 23 world countries by 2100 the population is expected to decline by more than 50 percent. In China by then, according to research, the population should drop from 1.4 billion to just 732 thousand. Population growth should be in North Africa, the Middle East and most of all sub-Saharan Africa, where the population will triple in the next 80 years.
