The population of the world as of today is 7 billion 924 million people. Is it possible to calculate the number of people who have lived at all times? Let’s look for an answer to this question.
paleodemographyis interested in birth and death statistics of populations that lived in the past and tries to answer this question as much as possible.
modern human history more than 99% It is not possible to give a definite answer to this question as it has not been recorded, but it is possible to make a rough estimate thanks to some calculations.
As a result of evolution, “man” has passed through various stages, so there is no definite time when we can start counting.
It is not easy to determine when humanity actually emerged. The earliest hominins are thought to have appeared around 7 million BC. The earliest species of the genus Homo appeared around 2 million to 1.5 million BC. The available evidence is modern of homo sapiens It appears to have originated around 190,000 BC.
We evolved from pre-human ancestors before this date, and as we go back there will be transitions to less human-like creatures. Since there is no sharp distinction We cannot say exactly where humanity began.
So where do we start counting?
The number of people who lived before modern humans is almost nothing compared to the total number of humans, because they did not have a population that was multiplying as fast as we do. Therefore, they do not have a serious effect on the computation. 50,000 BC It is a good starting year for a computationally reliable estimate, because it is possible to more or less estimate the number of people in that period.
According to calculations based on various assumptions, the answer to this question is approximately “117 billion”.
The number of people living today is approximately the number of people who have lived and disappeared. 7% of up to.
The human population in different periods according to paleodemographic statistics:
- 190,000 BC 2
- 50,000 2,030,625 BC
- 8000 5,000,000 BC
- AD 1 300,000,000
- 1200 450,000,000
- 1650 500,000,000
- 1750 795 million
- 1850 1,265 million
- 1900 1,656,000,000
- 1950 2,516 million
- 1995 5,760,000,000
- 2011 6,987,000,000
- 2020 7,772,850,162
- 2035 8,936,903,068
- 2050 9,875,704,167
at Texas A&M University demographer Dudley Poston Jr., who was a resident, extended the analysis to 190,000 BC to reveal the estimated population distribution by period. It is also predicted that the population will increase by 4 billion more by 2050.
Although we are a slow-breeding animal species compared to other species, the damage we inflict is too much. cause of our extinction probably due to the problems of high population growth.
