## Demographics
### Sorsogon Ayta Language

In 2010, UNESCO released its third volume of Endangered Languages in the World, with three critically endangered languages being in the Philippines. One of these is Southern Ayta (Sorsogon Ayta), which had 150 estimated speakers in 2000. The language was classified as "Critically Endangered", meaning the youngest speakers are grandparents and older, and they speak the language partially and infrequently and hardly pass it to their children and grandchildren. If the remaining 150 people do not pass their native language to the next generation of Sorsogon Ayta people, their indigenous language will be extinct within a period of 1 to 2 decades.
The Sorsogon Ayta people live only in the municipality of Prieto-Diaz. They are one of the original Negrito settlers of the Philippines. They belong to the Aeta people classification but have distinct language and belief systems unique to their own culture and heritage.
