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 I[30]

Two seasons: dry from November to April, wet for the rest of the year, with the heaviest rain from June to September.

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
12.9% 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 13 of every 100 people in Santo Domingo lived below the poverty line in 2021 (12.9%)[18]

The PSA's model for every town puts it between 10.6% and 15.2%, with 90% confidence.

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

History & Identity

Its story

The town's tourism page calls the St. Dominic parish church one of the oldest in Ilocos Sur, and says Diego Silang served as bell ringer in its bell tower.[10]

Santo Domingo was already a municipality in January 1907, when the Election Law placed it in the first district of Ilocos Sur.[11]

The Japanese troops built the docking area at Puerto Beach in Barangay Calay-ab during World War II, according to the town's tourism page.[10]

A monument to Rizal's 'Mi Ultimo Adios', engraved in four languages, was put up at the town plaza in 1972.[10]

Timeline

  1. 9 January 1907

    Act No. 1582 lists Santo Domingo among the municipalities of Ilocos Sur's first election district.[11]

  2. 1972

    Rizal monument erected at the town plaza.[10]
