Do you know 108 billion people were born on this earth?

Estimates published in 2015 by the US Census Bureau said that there have been 108.2 billion people born on Earth in the past, 100.8 billion have died and now "only" about 7, 4 billion people are living.

In other words, the death toll is 14 times more than the number of people alive and we are only among nearly 7% of those who have lived on this Earth, the remaining 93% are dead. In a good assumption, if all turned into zombies, ghosts, . then perhaps overwhelming the living in just a few minutes.

The death toll is 14 times more than the number of people who live and we are only among nearly 7% of those who have lived on this Earth.

So how can researchers make these estimates? First, the US Census Bureau (PRB) chose the year 50,000 BC as the first milestone. This is the time when modern Homo Sapiens appeared. Scientists still debate this timeline because some of the ideas suggest that the surname began appearing on Earth millions of years ago. However, the 50,000 BC mark was still chosen by PRB and many other large organizations.

Of course, the number of people born later is also speculated by researchers, based on the information obtained. Life expectancy is initially quite low due to lack of medical conditions, food problems, climate change, mutual killing and many other issues that make early population growth quite slow. . At that time, the rate of neonatal mortality was up to 500/1000 or higher. Below is the details of the world population situation through each stage.

The situation of world population through each stage.

Interestingly, we can see that the population growth rate from year 1 to 1650 is quite slow due to the impact of the bubonic outbreak . To the industrial revolution until now, the population began to explode so far. From 1850 until now, the world number has increased 6 times. Of course, above are only relative estimates based on population growth rate, birth rate, . and impact events. However, it also partly provides information about the development history of mankind from the past to present.
