To answer the question: “how many people have there been on Earth?”, we must take into account technological advances and especially medicine.
With this doubt often present throughout the history of humanity, many believe that today there are more people alive than dead. However, according to the average calculation carried out, this association proves to be incorrect and can be quite surprising.

Furthermore, it is interesting to point out that until the mid-1900s, around 1.6 billion human beings were alive and the number multiplied exponentially, like never before, during the last 100 years.
After all, can we really count this number?
Despite being a very difficult task historically speaking, enumerating how many human beings have lived on Earth has become increasingly simple.
From the 1800s onwards, we began to register individuals who were born and also collect their taxes.
The difficulty begins when we begin to understand that the history of humanity dates back to much more than 60 thousand years ago, when modern human beings left Africa.
This makes it necessary to reach a quantity that represents all these millennia of life and history of human beings on Earth.

To solve this problem and easily understand how many people were here, researchers at the Population Reference Bureau (PRB) use a method that can help.
In 2012, in response to the BBC, it was reported that to arrive at the number it was necessary to use data on the population's life expectancy in comparison with the number of live births in different regions.
Using such data, it was revealed that around 117 billion people have already passed through Earth at any moment. Therefore, showing that there were many more individuals, compared to the current 8 billion.
117 billion people have existed on Earth
Although difficult to believe, the number reaches this level and, even so, there is still controversy about it. Possibly, we have had more people on Earth throughout history.
In any case, when taking into account only the data indicated by PRB, we understand that the number of people who have already passed through Earth is extremely high.
Furthermore, this high amount is due to birth rates and also to more than 190 thousand years ago. W. of history recorded only in parts.
It is possible to say that countless humans were here and, at some point, left part of their history behind. Thus, they guided the advancement of civilization and cultures that we find today throughout the world.
