Climate

Climate typeClimate typePAGASA sorts the country's climate into four types by when the rain falls. 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 II^[30]

No dry season. The rain is heaviest from December to February, and no month is truly dry.

Life & Economy

About 25 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: 24.7% of people^[18]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 25 of every 100 people in Tiwi lived below the poverty line in 2021 (24.7%)^[18]

The PSA's model for every town puts it between 21.2% and 28.2%, with 90% confidence.

History & Identity

Stories from Bicol Region

Tiwi has no Story of its own yet. This one is about Bicol Region, which Tiwi is part of.

Film, 0:56
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 town's own history page says the name comes from tigbi, a Bikol word for a taro-like plant that grew plentifully in the area. Spanish writers changed it to Tibi and Tivi, and it later became Tiwi.^[10]

Its story

Tiwi was once a barrio of Malinao in the late 1600s, and the town's history page says it became a recognised town in 1696.^[10]

Spanish friars recorded Tiwi as a visita of Malinao in 1658. The Franciscans and the reduccion system brought the people into the Catholic faith, and St. Lorenzo Martir became its patron.^[10]

According to the town's page, Tiwi separated from Malinao in 1776 after more than a century as a visita and became a pueblo, with Domingo Marcilla as its first appointed gobernadorcillo.^[10]

In the 19th century, Moro raids wrecked a large part of the original pueblo, leaving ruins like the old church of Baybay.^[10]

Under American rule many residents who had fled to the mountains returned to the poblacion, and the population reached 12,556 by 1935.^[10]

In the Japanese period Albay became a landing site and many structures in Tiwi were destroyed by aerial bombing.^[10]

Tiwi is known for abaca, pottery and hot springs, and a geothermal power plant has operated there since the 1970s.^[10]
