Map Description:
This map shows the areas where indigenous languages were spoken in The Philippines. Most of the languages belong to the Malayo-Polynesian subgroup of the Austronesian language family, however Chavacano, a Spanish based creole language and also Tausug, a lingua franca are also represented. Tausug is found in the southern islands, where trade and contact amongst other Austronesian language speaking indigenous peoples was common.

This original map was made by vectorizing data from the MultiTree language database and the Atlas of the World's Languages.

Map Description:
UNESCO’s Atlas of the World’s Languages in Danger is a database intended to raise awareness about language endangerment and the need to safeguard the world’s linguistic diversity among policy-makers, speaker communities and the general public, and to be a tool to monitor the status of endangered languages and the trends in linguistic diversity at the global level.

Degrees of endangerment
The map designates the degrees of endangerment as based on UNESCO’s Language Vitality and Endangerment framework.

This establishes six degrees of vitality/endangerment based on nine factors. Of these factors, the most salient is that of intergenerational transmission.

Degree of endangerment	Intergenerational Language Transmission
safe	language is spoken by all generations; intergenerational transmission is uninterrupted >> not included in the map
vulnerable	most children speak the language, but it may be restricted to certain domains (e.g., home)
definitely endangered	children no longer learn the language as mother tongue in the home
severely endangered	language is spoken by grandparents and older generations; while the parent generation may understand it, they do not speak it to children or among themselves
critically endangered	the youngest speakers are grandparents and older, and they speak the language partially and infrequently
extinct	there are no speakers left >> included in the Atlas if presumably extinct since the 1950s
