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]
Graph of world population over the past 12,000 years . As a general rule, the confidence of estimates on historical world population decreases for the more distant past. 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.
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. Given the lack of population records prior to the 1950s, there are many gaps in our record of demographic history.
The Neolithic demographic transition was a period of rapid population growth following the adoption of agriculture by prehistoric societies (the Neolithic Revolution).It was a demographic transition caused by an abrupt increase in birth rates due to the increased food supply and decreased mobility of farmers compared to foragers.
Historical demography is the quantitative study of human population in the past. It is concerned with population size, with the three basic components of population change (fertility, mortality, and migration), and with population characteristics related to those components, such as marriage, socioeconomic status, and the configuration of families.
The population brought to South Asia by coastal migration appears to have remained there for some time, during roughly 60,000 to 50,000 years ago, before spreading further throughout Eurasia. This dispersal of early humans, at the beginning of the Upper Paleolithic, gave rise to the major population groups of the Old World and the Americas.
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).
This article lists historical urban community sizes based on the estimated populations of selected human settlements from 7000 BC – AD 1875, organized by archaeological periods.
