About 70,000 years ago existed less than 1000 individuals. This are our all ancestors.
We can make a difference in the populison growth from 300,000,000 up to 8,000,000,000 in the last 2000 years.
So in the first 70,000 years lived in average about 150 million people and if all 50 years died about 50% of this people then this means 70,000/50*150,000,000/2 =70,000*150,000,000/100=700*150,000,000=7*1,500,000,000 =>
~10 billion people died before Christ.
From the birth of Christ to the year 1804 the population grew from 300,000,000 to 1,000,000,000. So in average lived 650,000,000 and if in 50 years died 50% of this people then 1800/50*650,000,000/2=18*650,000,000 => ~12 billion people died between the birth of Christ and the end of the Holy Roman Empire of German Nation.
intermediate total: maximal 22 billion people
But how many died in the last 200 years?
- 1804: 1 billion
- 1927 (after 123 years): 2 billion
- 1960 (after 33 years): 3 billion
- 1974 (after 14 years): 4 billion
- 1987 (after 13 years): 5 billion
- 1999 (after 12 years): 6 billion
- 2011 (after 12 years): 7 billion
- 2022 (after 11 years): 8 billion human beings.
(1+2)/2 for 123 years: 123/50*(1+2)/4=1,850,000,000
(2+3)/2 for 33 years: 33/50*(2+3)/4=825,000,000
(3+4)/2 for 14 years: 14/50*(3+4)/4=490,000,000
(4+5)/2 for 13 years: 13/50*(4+5)/4=585,000,000
(5+6)/2 for 12 years: 12/50*(5+6)/4=660,000,000
(6+7)/2 for 12 years: 12/50*(6+7)/4=780,000,000
(7+8)/2 for 11 years: 11/50*(7+8)/4=825,000,000
about
6 billion human beings died in the last 200 years.
In total 22+6=
28 billion human beings died.
So I guess it are less than 30 billions who died.
