At the new documentation page you will find the documentation for the indicators compiled by Gapminder, including population. There you can also download an Excel-file that includes not only all the data, but also information on sources and estimation methods for each observation.
To the extent possible we have also used this information to give each observation one of these “data quality ratings”:
- Very Poor data quality – the population figure is based on guesstimates or rough extrapolations
- Poor data quality
- Fair data quality
- Good data quality
- Very Good data quality – the population figure is based on a rigourous census or equivalent
