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[34]

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 21 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
21.1% of people[22]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 21 of every 100 people in San Marcelino lived below the poverty line in 2021 (21.1%)[22]

The PSA's model for every town puts it between 17.2% and 25.1%, with 90% confidence.

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

History & Identity

How it got its name

Local traditionThe town's own history says San Marcelino was named after Marcelino, its first teniente del barrio.[10]

Its story

Local traditionThe town's own history says Ilocano settlers first lived on Vega Hill, then moved to Mangaring, now Barrio Linasin, and finally to the present town centre. It says a Spanish priest, Father Guillermo, befriended them, and the friars set up barrio heads.[10]

An 1880 book describes San Marcelino as a pretty town with a future, on fertile ground.[11]

The first election, on 14 January 1906, made Matias Apostol the first elected president of the town.[10]

Act No. 945 of 1903 joined Castillejos and San Antonio to San Marcelino. They were separated again in 1908 (San Antonio) and 1910 (Castillejos).[12, 13, 14]

Timeline

  1. 15 October 1903

    Act No. 945 of 15 October 1903 reduced Zambales from twenty-five municipalities to fifteen. San Marcelino was kept and took over the territory of Castillejos and San Antonio.[12]

  2. 14 January 1906

    Local traditionSan Marcelino held its first election, and Matias Apostol became its first elected president.[10]
