Life & Economy

About 41 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: 40.7% 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 41 of every 100 people in Libmanan lived below the poverty line in 2021 (40.7%)^[17]

The PSA's model for every town puts it between 37.1% and 44.4%, with 90% confidence.
