According to Lobel (2013),^[4] there are no speakers of Inagta Partido under 60. It is a moribund language. The Ethnologue cites a report from 2000 that there were then only five speakers from an ethnic population of about 1,000.^[5]

Inagta Partido has borrowed heavily from Bikol languages such as Bikol Naga and Bikol Partido, but has a non-Bikol substratum.^[6]
