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.
Demographic history of Greece. Agriculture came to Europe from Asia via the Balkans, which were one of the first areas in Europe to experience the neolithic transformation. As early as 5000 BC the area's Mesolithic population had been transformed into a peasant society of 250,000 people, which in turn grew to 2,000,000 people by the Bronze Age.
The current world population growth is approximately 1.09%. [7] People under 15 years of age made up over a quarter of the world population (25.18%), and people age 65 and over made up nearly ten percent (9.69%) in 2021. [7] The world population more than tripled during the 20th century from about 1.65 billion in 1900 to 5.97 billion in 1999.
Based on a dataset of average population density of hunter-gatherer groups collected by Lewis R. Binford, which indicate a mean density of 0.1223 humans per km 2 and a median density of 0.0444 humans per km 2, the combined human population of Africa and Eurasia at the time of the LGM would have been between 2,998,820 and 8,260,262 people.

Life expectancy at birth in the Roman Empire is estimated at about 22–33 years. [9] [notes 1] For the two-thirds to three-quarters of the population surviving the first year of life, [10] life expectancy at age 1 is estimated at around 34–41 remaining years (i.e. expected to live to age 35–42), while for the 55–65% surviving to age 5, life expectancy was around 40–45.
