These sources like YouTube are extremely unreliable sources. Whoever made those YouTube videos most likely has the UN/USCB sources.] This is a list of population milestones by country (and year first reached). Only existing countries are included, not former countries.
Log-log graph depicting estimates of the world population from 10,000 BCE to 2000 CE Prehistoric demography, palaeodemography or archaeological demography is the study of human and hominid demography in prehistory. [1] More specifically, palaeodemography looks at the changes in pre-modern populations in order to determine something about the influences on …
World population milestones went unnoticed until the 20th century, since there was no reliable data on global population dynamics.

A late human population bottleneck is postulated by some scholars at approximately 70,000 years ago, during the Toba catastrophe, when Homo sapiens population may have dropped to as low as between 1,000 and 10,000 individuals. [5][6] For the time of speciation of Homo sapiens, some 200,000 years ago, an effective population size of the order of ...

Global population gained 50% in the 5th millennium BC, and 100% each millennium until 1000 BC, reaching 50 million people. After the beginning of the Iron Age, growth rate reached its peak with a doubling time of 500 years. However, growth slackened between 500 BC and 1 AD, before ceasing around 200 AD.
