The number of inhabitants on Earth will exceed seven billion by the end of the year, announced the French Institute for Demographic Studies (INED), reports AFP.
The limit of six billion inhabitants was exceeded in 1999, according to INED.
It took 12 years for the number of people on Earth to reach seven billion, and it will take 14 years to reach the next mark of eight billion as the world's population growth rate slows, the Institute estimates.
After that, the world population should stabilize at between nine and ten billion until the end of the century.
The growth of the population in the world will decrease this year to 1,1 percent, while 50 years ago, it was two percent.
Today, the number of children per woman is an average of 2,5, while half a century ago it was five. However, the differences in the world are huge, from Niger, where a woman gives birth to an average of seven children, to Taiwan, where the average is 0,9.
Population growth is most pronounced in sub-Saharan Africa, parts of the Arabian Peninsula and in areas from Afghanistan to northern India.
Currently, the group of seven most populous countries in the world consists of China (1,33 billion inhabitants), India (1,17 billion), USA (306,8 million), Indonesia (243,3 million), Brazil (191,5), Pakistan (180,8 .162,3) and Nigeria (XNUMX).
By 2050, India (estimated at 1,69 billion) should overtake China (1,31), Nigeria (433 million) and the United States (423 million), according to INED.
