Huff et al. (2010) rejected all models with an ancient effective population size larger than 26,000. [9] For ca. 130,000 years ago, Sjödin et al. (2012) estimate an effective population size of the order of 10,000 to 30,000 individuals, and infer an actual "census population" of early Homo sapiens of roughly 100,000 to 300,000 individuals.

This is a list of dates associated with the prehistoric peopling of the world (first known presence of Homo sapiens). The list is divided into four categories, Middle Paleolithic (before 50,000 years ago), Upper Paleolithic (50,000 to 12,500 years ago), Holocene (12,500 to 500 years ago) and Modern ( Age of Sail and modern exploration).
A 2016 study presented an analysis of the population genetics of the Ainu people of northern Japan as key to the reconstruction of the early peopling of East Asia. The Ainu were found to represent a more basal branch than the modern farming populations of East Asia, suggesting an ancient (pre-Neolithic) connection with northeast Siberians. [115]
Robust population data exist only for the last two or three centuries. Until the late 18th century, few governments had ever performed an accurate census. In many early attempts, such as in Ancient Egypt and the Persian Empire, the focus was on counting merely a subset of the population for purposes of taxation or military service. [2]
Many of the figures are uncertain, especially in ancient times. Estimating population sizes before censuses were conducted is a difficult task. [1] Neolithic settlements
Demographic history is the reconstructed record of human population in the past. Given the lack of population records prior to the 1950s, there are many gaps in our record of demographic history.

With the partial exception of Vučedol, the Danubian cultures, which had been so buoyant just a few centuries ago, were wiped off the map of Europe. The rest of the period was the story of a mysterious phenomenon: the Beaker people , which seemed to be of a mercantile character and to have preferred being buried according to a very specific ...
