Movement Insights/Comparison datasets
Countries
[edit]The New Readers project created a country comparison dataset in 2016. We could adopt this as a product.
We would need to provide a bidirectional wiki-country mapping (with possibly a selection of different mapping types: most commonly accessed language, languages accounting for more than 10% of pageviews...)
Language
[edit]Ethnologue is the best data source. The Wikipedia Cultural Diversity Observatory created a language-territories mapping, partly with Ethnologue data.
