The PRB puts the figure at 117 billion as of 2020, estimating that the current world population is 6.7% of all the humans who have ever lived. [148] Haub (1995) prepared another figure, updated in 2002 and 2011; the 2011 figure was approximately 107 billion.
An estimate on the "total number of people who have ever lived" as of 1995 was calculated by Haub (1995) at "about 105 billion births since the dawn of the human race" with a cut-off date at 50,000 BC (beginning of the Upper Paleolithic), and inclusion of a high infant mortality rate throughout pre-modern history.

Assume, for simplicity, that the total number of humans who will ever be born is 60 billion (N 1), or 6,000 billion (N 2). [6]If there is no prior knowledge of the position that a currently living individual, X, has in the history of humanity, one may instead compute how many humans were born before X, and arrive at say 59,854,795,447, which would necessarily place X among the first 60 billion ...

It took over two million years of human prehistory and history for the human population to reach one billion and only 207 years more to grow to 7 billion. [147] The combined biomass of the carbon of all the humans on Earth in 2018 was estimated at 60 million tons, about 10 times larger than that of all non-domesticated mammals.
