And the second chunk is country estimates that only reaches back to 1800.\n\nFor the first chunk, several sources were used. You can learn more at https://docs.google.com/spreadsheets/d/1hkLbEilJbl630IG68q-aQJlUjuTFm9b_12nQMVd1sZM/edit#gid=0. For the second chunk, Gapminder uses UN population data between 1950 to 2100 from the UN Population Division World Population Prospects 2019, and the forecast to the year 2100 uses their medium-fertility variant.\n\nFor years before 1950, this version uses the data documented in greater detail by Mattias Lindgren in version 3. The main source was Angus Maddison's data, which CLIO Infra Project maintained and improved. Note that when combining version 3 with the new UN data, the trends for a few countries didn't match up in the overlapping year 1950.\n\nMinor adjustments were made to the years before and after to smooth out discrepancies between the two sources and avoid spurious jumps in Gapminder's visualisations.\n\nVisit https://www.gapminder.org/data/documentation/gd003/ to learn more about the methodology used and the data from back to 10,000 BC.","producer":"Gapminder","citationFull":"Gapminder Population v7 (2022)","attribution":"Gapminder, Population v7 (2022)","attributionShort":"Gapminder","versionProducer":"v7","urlMain":"http://gapm.io/dpop","urlDownload":"https://gapm.io/dl_popv7","dateAccessed":"2023-03-31","datePublished":"2022-10-19","license":{"url":"https://docs.google.com/document/d/1-RmthhS2EPMK_HIpnPctcXpB0n7ADSWnXa5Hb3PxNq4/edit?usp=sharing","name":"CC BY 4.0"}},{"id":69,"title":"World Population Prospects","description":"World Population Prospects 2022 is the 27th edition of the official estimates and projections of the global population that have been published by the United Nations since 1951.
