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.
This is a list of countries by population in 1000. The bulk of these numbers are sourced from Alexander V. Avakov's Two Thousand Years of Economic Statistics , Volume 1, pages 12 to 14, which cover population figures from the year 1000 divided into modern borders.
Population of the world from 10,000 BC to 2000 AD (logarithmic scale) Estimating the ancestral population of anatomically modern humans, Colin McEvedy and Richard Jones chose bounds based on gorilla and chimpanzee population densities of 1/km 2 and 3-4/km 2, [1] respectively, then assumed that as Homo erectus moved up the food chain, they lost an order of magnitude in density.
This article lists the largest human settlements in the world (by population) over time, as estimated by historians, from 7000 BC when the largest human settlement was a proto-city in the ancient Near East with a population of about 1,000–2,000 people, to the year 2000 when the largest human settlement was Tokyo with 26 million.

England – The population of England, between 1.25 and 2 million in 1086, [8] is estimated to have grown to somewhere between 3.7 million [9] and 5–7 million, [1] although the 14th-century estimates derive from sources after the first plague epidemics, and the estimates for pre-plague population depends on assumed plague mortality, the ...
[3] [4] Old estimates put the global population at 9 billion by 2037–2046, 14 years after 8 billion, and 10 billion by 2054–2071, 17 years after 9 billion; however these milestones are likely to be reached far sooner.
