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: 20.7% 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: 1st class^[4]

About 21 of every 100 people in San Antonio lived below the poverty line in 2021 (20.7%)^[20]

The PSA's model for every town puts it between 18.5% and 23.0%, with 90% confidence.

Its story

San Antonio was earlier called Pamisaraoan. The NHCP marker says it was named a barrio in 1836.^[9]

Sources differThe marker says Ilocano pioneers from Paoay, Ilocos Norte, explored and settled the place in 1830, and that it became a municipality on 12 May 1849. An 1880 book says the Recollects founded it in 1836.^{[9, 10]}

Act No. 945 of 1903 merged San Antonio into San Marcelino, and Executive Order No. 7 of 1908 separated it again.^{[11, 12]}
