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[31]

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 13 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
13.3% 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 13 of every 100 people in Reina Mercedes lived below the poverty line in 2021 (13.3%)[19]

The PSA's model for every town puts it between 10.2% and 16.3%, with 90% confidence.

The PSA rates this estimate's reliability as acceptable rather than high: read it as a guide.

One account gives Itugud as an earlier name of the place, and the page adds that Dominican records show the old Itugod, founded by Fray Pedro Jimenez in 1678, is in fact Barangay Lenzon in Gamu, outside Reina Mercedes.[10]

In October 1903 Act No. 941 abolished the municipality of Reina Mercedes as a separate unit and joined its territory to Cauayan.[11]
