Looking for geospatial information on linguistics.
Looking for world wide data with national and subnational data. Data should include what regions speak which language(s).
Does this data exist?

I know that this data exists for Africa. Here is the link.
There is a variable under the "Ethno Linguistic" group labeled as Language Families 2001. Hope this piece helps.
The polygons seem to be served from a geoserver. I looked at the HTML and here is an example of a polygon:
