About these figures
Why a median and not an average?
The median is the value in the middle when the members are sorted: half are above it and half below. It is not pulled up or down by one very large or very small country, and it treats each member equally. It is calculated on this site from the published country values.
How does this differ from the official group figure?
Official aggregates, such as the EU figure from Eurostat, are calculated by the source and weighted by population or economic size. Where the source publishes one, it is on the measure pages next to the countries. More about aggregates
