TEMPO.CO, Washington – Earth's population is estimated to reach 11 billion in 2100, after United Nations reported that 7 billion people currently living on the planet in 2011. The increase is considerably high because there were only around 5 million people in 8,000 BC and around 1 billion people in 1805.
Africa, with a current population of 1,1 billion people, will likely to reach 4,2 billion in 2100 due to the decreasing rate of infertility, as confirmed by Adrian Raftery, a statistics expert at the University of Washington.
The entire world will also experienced a great population boom with an exception of Europe, which will likely show higher mortality rate.
A statistics model estimated that human population will reach 9 to 13 billion in 2100. However, assuming that birth rate can average at 0.5, United Nation predicted that the range could possibly reached 7 to 17 billion of population, a far larger number.
