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^[32]

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 14 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: 14.4% 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: 2nd class^[4]

About 14 of every 100 people in Cauayan City lived below the poverty line in 2021 (14.4%)^[20]

The PSA's model for every town puts it between 12.4% and 16.4%, with 90% confidence.

All Stories

Official name: City of Cauayan^[4]
Created: Cauayan became a component city under Republic Act No. 9017, approved on 28 February 2001. The city was to gain corporate existence when voters ratified it in a plebiscite within sixty days of approval.^[9]

Its story

The same profile says Cauayan was founded in 1740, which it says is 116 years before Isabela became a province.^[10]

It says Isabela was created as a province by royal decree on 1 May 1856, and Cauayan became one of its towns. After a series of floods the town site was moved to its present place.^[10]

In 1903 Act No. 941 merged the neighbouring municipality of Reina Mercedes into Cauayan.^[11]

In 1949 the western part of Cauayan was split off to form Cabatuan, and Cauayan kept the rest of its land.^[12]

Republic Act No. 9017 turned the municipality into the component City of Cauayan on 28 February 2001. The DAP profile says voters ratified it by a majority on 30 March 2001.^[9]
