Maybe it has crossed our minds a fad question: How many people have ever been born and inhabited this planet earth? Anyone knows ? for sure no one knows the exact amount, but in fact it can be estimated using several calculation methods.
Some scientists have succeeded in estimating by using data on the number of births in the 1st year after Christ, namely reaching 80 births for every 1,000 people. This birth rate turns out to continue to fall each period. Until 2011, the birth rate was only 23 people per 1,000 people.
Is Haub, a scientist from the country of uncle sam USA. Together with its research institute: the Population Reference Bureau (RPB) claims to have succeeded in calculating the estimated number of humans who have ever been born and lived on Earth.
More specifically, the estimated calculation was carried out by estimating the population from 50,000 BC
According to Carl Haub, "In total, there are around 108.2 billion people who have been born to earth since human history appeared.
Haub said, if you don't count the number of people who are still alive, around 7.4 billion, then the total number of people who have died is around 100.8 billion. That figure is equal to 14 times the number of people who are still alive today.
In about 50,000 BC, there were only two humans (Adam and Eve). Then In 8000 BC there were about 5 million human population. Then in 1 AD there were a total of 300 million people, and so on until 2011 with a population of 6.9 billion," said Haub.
