Umiray Dumaget is spoken along the Pacific coast of eastern Luzon, Philippines, from just south of Baler, Aurora, to the area of Infanta, Quezon, and on the northern coast of Polillo Island. Himes (2002) reports little dialectal variation.
Reid (1994) reports the following locations for Umiray Dumaget (Central Agta).
Umiray Dumaget is difficult to classify. Himes (2002) posits a Greater Central Philippine connection. However, Lobel (2013) believes that Umiray Dumaget may be a primary branch of the Philippine languages, or may be related to the Northeastern Luzon languages, Sambali-Ayta (Central Luzon), or Manide and Inagta Alabat. According to Lobel (2013), Umiray Dumaget does not subgroup in the Central Philippine or even Greater Central Philippine branches.
Umiray Dumaget is under Greater Central Philippine language family according to Glottolog and Ethnologue.
