Gapminder combines data from multiple sources into unique coherent time-series that can’t be found elsewhere.

Below are links to documentation describing how we have combined the sources in each case. For the sake of transparency, whenever allowed to share the underlying data, we make our complete calculations available for download, often in Excel files. In most of these files the details are not documented, as we haven’t had time to describe every little step in our data process. But our data is constantly being improved by people who help find problems. If you have questions, please email info (at) gapminder (dot) org. Read more about our data combination methods here »

Each documentation page has a version number and links to the previous versions. Whenever we update the data, or make other significant changes in the documentation, we make a new version.
