WORLD POPULATION OVER 12000 YEARS (VARIOUS SOURCES (2016))
Variable description Total world population
Variable geographic coverage Global
Variable time span 10,000 years BCE to 2015 (plus projections by the UN until 2100)
Data published by The History Database of the Global Environment (HYDE) collected the data by earlier publications. For the ‘OurWorldInData’-series we used various sources: The data for the period before 1900 are taken from the History Database of the Global Environment (HYDE). The data for the World Population between 1900 and 1940 is taken from the UN puplication ‘The World at Six Billion’. The annual data for the World Population between 1950 and 2015 is taken from the UN’s World Population Prospects: The 2015 Revision. It is the series ‘Total Population - Both Sexes’ online available here.
Data publisher’s source HYDE aggregated estimates published in earlier publications. The series are named after these publications.
