How we process data at Our World in Data
All data and visualizations on Our World in Data rely on data sourced from one or several original data providers. Preparing this original data involves several processing steps. Depending on the data, this can include standardizing country names and world region definitions, converting units, calculating derived indicators such as per capita measures, as well as adding or adapting metadata such as the name or the description given to an indicator.
At the link below you can find a detailed description of the structure of our data pipeline, including links to all the code used to prepare data across Our World in Data.
Notes on our processing step for this indicator
The population time series is constructed by combining data from multiple sources:
-
10,000 BCE - 1799: Historical estimates by HYDE (v3.2). Includes some data from Gapminder (Systema Globalis).
-
1800-1949: Historical estimates by Gapminder. Includes some data from HYDE (v3.2) and Gapminder (Systema Globalis).
-
1950-2021: Population records by the UN World Population Prospects (2022 revision). Includes some data from HYDE (v3.2), Gapminder (Systema Globalis) and Gapminder (v7).
-
2022-2100: Projections based on Medium variant by the UN World Population Prospects (2022 revision).
