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 III[29]

No clear rainiest time of year, and a short dry season of one to three months, in December to February or in March to May.

Read by Scene off PAGASA's climate map, so approximate: the type that covers most of the place's land.

Life & Economy

About 16 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
15.6% 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
2nd class[4]
About 16 of every 100 people in Piagapo lived below the poverty line in 2021 (15.6%)[18]

The PSA's model for every town puts it between 9.9% and 21.4%, with 90% confidence.

The PSA says caution must be observed in using this estimate: read it as a rough guide only.
