is now reclassified as First Class municipality
in the province
. According to the 2007 census, it has a population of 63,888 people in 11,715 households.
The town's economy is generally agricultural. Its major products include rice, root crops such as sweet potato and gabi

The municipality was founded during the early Spanish Colonization of the Bicol Peninsula
. In 1605, Father Baltazar de los Reyes converted 12 leading natives of the area to Christianity
in one day, forming the foundation of the community now known as Oas.
There are three stories that tell the origin of the name of Oas:
