Life & Economy

About 7 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: 6.5% of people^[17]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 7 of every 100 people in Bacnotan lived below the poverty line in 2021 (6.5%)^[17]

The PSA's model for every town puts it between 5.3% and 7.8%, with 90% confidence.

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

How it got its name

Local traditionLocal lore says the name comes from bakunuttan, meaning to flog, a word linked to the overthrow of a harsh tribal chieftain.^[9]

Its story

It was one of the twelve original towns of La Union when the province was created in 1850.^[9]

In October 1903 the Philippine Commission kept Bacnotan's boundaries as they were when it cut the province's municipalities from fifteen to twelve.^[10]

The town took part in resistance in the Spanish-American War and in the Second World War, notably at Baroro Bridge.^[9]

After the war it briefly served as the provincial capital. The cement industry at Quirino and Don Mariano Marcos Memorial State University at Sapilang are later developments.^[9]
