Life & Economy

Poverty, 2021Poverty incidenceHow many of every 100 people live in families whose income is below the poverty line: what a person needs in a year for food and other basic needs, as the PSA sets it for each province. It is an estimate, from a survey or, for a town, a statistical model, so the PSA gives a range it is likely to fall in.More in the glossary
26.1% of people[19]Below the poverty line, by the PSA's estimate for every town.

History & Identity

Created
Mahayag was created by Executive Order No. 393 of President Garcia, dated 10 May 1960, from barrios of Molave and Dumingag.[9]

Its story

The Subanen were the first to live in the area, along the river banks where they made their living.[11]

In early 1939 early Christian settlers reached the plains of Mahayag looking for farmland, and the Subanen retreated to the mountains.[11]

Visayan migrants who came after World War II found the place heavily forested.[11]

Executive Order No. 393 made Mahayag an independent municipality out of 20 barrios and sitios of Molave and three of Dumingag.[9]

The town page says the town site was donated by Zacarias dela Torre and Pedro Alquizar.[11]

Sources differThe town's page dates the order 9 May 1960, while the order itself is dated 10 May 1960.[9, 11]

Timeline
