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[32]

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

Life & Economy

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

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 18 of every 100 people in Castillejos lived below the poverty line in 2021 (17.9%)[20]

The PSA's model for every town puts it between 14.6% and 21.2%, with 90% confidence.

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

History & Identity

Created
Castillejos was made a municipality again by Executive Order No. 57 of July 1909, which separated it from its 1903 host municipality. The order took effect on 1 January 1910.[9]

Its story

The pueblo of Uguic was created in 1743, and an 1880 book also says the Recollects founded Castillejos that year.[10, 11]

The town took the name Castillejos in 1863.[10]

In 1896 a group from Castillejos joined the revolutionary forces that captured the Spanish troops in Zambales.[10]

Act No. 945 of 1903 merged Castillejos into San Marcelino. Executive Order No. 57 of 1909 made it a separate municipality again from 1 January 1910.[9, 12]

The marker says guerrillas under Ramon Magsaysay drove the Japanese from the Castillejos airstrip on 26 January 1945, and that the town was liberated four days later.[10]

  4. 15 October 1903

  5. July 1909 (effective 1 January 1910)

    Executive Order No. 57 of July 1909 separated Castillejos from San Marcelino and set it up again as its own municipality, with the territory it had before 1903. The separation took effect on 1 January 1910.[9]
