What helps us most
- The address of the page and the language you were using.
- For a quiz problem: the mode, the region, the level and what happened.
- For a data question: the country and the value you expected, ideally with a source.
Good to know
We read every message but cannot promise to answer each one. Country names, capitals and figures come from open data sets; when one of them is wrong at the source we report it there as well.
