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 IV[32]

Rain spread fairly evenly through the year, with no dry season.

Covers about 91 of every 100 parts of its land. Read by Scene off PAGASA's climate map, so approximate: the type that covers most of the place's land.

Life & Economy

About 30 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
29.8% of people[20]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 30 of every 100 people in Bayog lived below the poverty line in 2021 (29.8%)[20]

The PSA's model for every town puts it between 26.3% and 33.3%, with 90% confidence.

History & Identity

Created
Bayog became a regular municipality by Republic Act No. 4872, approved 8 May 1967, out of barrios and sitios of Buug.[9]

Its story

Large numbers of settlers began to stay permanently in the area in 1953; it had been thinly populated by native Subanen, and the barrio of Bayog grew under the municipality of Malangas.[11]

Settlement picked up when the Samar Mining Company built the SAMICO road, which the town's account says is 42 kilometres long.[11]

President Macapagal's Executive Order No. 112 of 1 October 1964 created a municipality of Bayog from 20 barrios and sitios of Buug.[12]

On 15 February 1966 that municipality was dissolved and went back to being a barrio of Buug, following the Supreme Court decision in Pelaez v. Auditor General.[11]

Congress then passed Republic Act No. 4872, creating Bayog again as a regular municipality in 1967.[11]
