Life & Economy

About 18 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: 17.7% 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 18 of every 100 people in Sinait lived below the poverty line in 2021 (17.7%)^[17]

The PSA's model for every town puts it between 14.8% and 20.6%, with 90% confidence.

Everything listed for Sinait in Now

How it got its name

Local traditionThe town's own page says Salcedo named the new pueblo Sin-nait, a local word meaning 'contest', because the people were always fighting small battles. It says the second 'n' was later dropped because the name was hard to say, and that a municipal council resolution of 1913 adopted Sinait as the official name.^[10]

Its story

The town's page says that before the Spaniards the place was a small village of a little over a hundred people called Tirongs, who sailed to other coasts and fought small tribal wars.^[10]

Sources differIt says Salcedo organised the place as a pueblo and called it Sin-nait; the page gives the year as 1535, which is earlier than Salcedo's expedition, and elsewhere gives 1735 for the establishment under Spain.^[10]

The church holds the black crucifix called Apo Lakay, believed to have come from Nagasaki, Japan, in 1620. In 1656 the image was taken to Vigan during an epidemic, and in 1660 building of a permanent church began.^[10]

In 1910 Don Brigido Yasaña became the first Filipino elected head of the municipality, with the title of Municipal President.^[10]
