Changes

The Ethnologue data was used to determine the dominant contemporary language family for each [[UN GeoRegion Codes | United Nations recognised country]] ([http://www.edegan.com/repository/Ethnologue-CountryDominantLanguage.txt Ethnologue-CountryDominantLanguage.txt]). The language families were then grouped in 'pseudo-families'. The pseudo-families are useful but strictly 'illegimate' unit of aggregation. Ethnologue recognizes six dominant top-level language families and a total of 94 contemporary language families. Of these, we group the 40 most used languages in 8 pseudo-families ([http://www.edegan.com/repository/Ethnologue-LanguageFamilies.txt Ethnologue-LanguageFamilies.txt]) for our classification purposes.

The 8 pseudo-families and the 40 families are:

*Afro-Asiatic

**AustralianAboriginal

**Eskimo-Aleut
