Type I has a dry season from November to April and a wet one for the rest of the year; Type II has no dry season, with the most rain from December to February; Type III has a short dry season; Type IV has rain spread through the year.More in the glossary

Type IV^[31]

Life & Economy

About 33 of every 100 people lived below the poverty line in 2021.

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: 33.0% of people^[19]Below the poverty line, by the PSA's estimate for every town.
Income classIncome classThe Department of Finance sorts provinces, cities and municipalities into classes by their average yearly income over recent years: 1st class has the most. It measures the local government's income, not how well off its people are.More in the glossary: 1st class^[4]

About 33 of every 100 people in Matnog lived below the poverty line in 2021 (33.0%)^[19]

The PSA's model for every town puts it between 28.9% and 37.0%, with 90% confidence.

Bicol Region
Bicol Region: the day Mayon moved a town
Tradition says Bicol is named for a bending river. On 1 February 1814 Mayon buried Cagsawa; the town moved to Daraga, and in 1914 the Bicol Region made a pilgrimage to the ruins.
Why It's Called That

All Stories

How it got its name

Local traditionThe provincial government says the name comes from the local word matonog, for the loud sound of the seas around the town.^[9]

Its story

Local traditionThe province says the first settlers were believed to be cave dwellers from Bacon. Malay settlers led by a chief, Sirangan, and his wife Hara-hara came long before 1570.^[9]

The first village stood near the mouth of the Matnog River, at a place now called Banuangdaan.^[9]

Matnog became an independent pueblo civil under Albay in 1800, along with Juban.^[10]

In 1863 Matnog became a parish separate from Bulusan.^[11]

The town was moved from its first site to where it stands now in 1898.^[9]

Matnog lies at the southernmost tip of Luzon, 71 kilometres from the provincial capitol, and is known for lumber, forest products, fish, nipa shingles, abaca and copra.^[9]
