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.

[27] [28] [29] Phosgene was then only infrequently used by the Imperial Japanese Army against the Chinese during the Second Sino-Japanese ...
Population of the present-day top seven most-populous countries, 1800 to 2100. Future projections are based on the 2024 UN's medium-fertility scenario. Chart created by Our World In Data in 2024. The following is a list of countries by past and projected future population. This assumes that countries stay constant in the unforeseeable future ...
Estimates of world population by their nature are an aspect of modernity, possible only since the Age of Discovery.Early estimates for the population of the world [10] date to the 17th century: William Petty, in 1682, estimated the world population at 320 million (current estimates ranging close to twice this number); by the late 18th century, estimates ranged close to one billion (consistent ...
The majority of world population growth today is occurring in less developed countries. According to United Nations population statistics, the world population grew by 30%, or 1.6 billion humans, between 1990 and 2010. [39] In number of people the increase was highest in India (350 million) and China (196 million).
The "Day of Seven Billion" was targeted by the United States Census Bureau to be in March 2012, [15] while the Population Division of the United Nations suggested 31 October 2011, [16] and the latter date was officially designated by the United Nations Population Fund (UNFPA) as the approximate day on which the world's population reached seven ...
