According to the 2020 census, it has a population of 53,146 people. Legend has it that the Manobo tribesmen first inhabited the area in the central part of Surigao del Sur. Sometime in the 1930s, five families who were engaged in fishing landed in the up-end of the river, and settled in the area for easy access to the fishing grounds. The area became known for its bountiful fish catch, and therefore more people from neighboring areas also came and settled. The distinctive visual quality of the area was an endemic species of tree known as "barobo", which was plentiful on the site of the settlement. Subsequently, the place became popularly known as Barobo.
