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
21.3% of people[21]Below the poverty line, by the PSA's estimate for every town.

About 21 of every 100 people in Iba lived below the poverty line in 2021 (21.3%)[21]

History & Identity

How it got its name

Iba began as the village of Paynaven. The Dominicans moved it in 1680 to its present site and renamed it Iba.[9]

Its story

A Spanish history in Blair and Robertson says Paynaven was moved inland to the site called Iba, and the new village took that name. It says the move was to get the village away from the fort commandant, and that families from Bolinao were brought to make Iba the capital.[10]

Iba later became the capital of Zambales. An 1880 book describes it as the capital, with the provincial government house, jail and civil guard barracks.[11]

In 1903 Act No. 945 joined Palauig to Iba. Executive Order No. 57 of 1909 separated Palauig again from 1 January 1910.[12, 13]

Timeline

  1. 1611

    The Recollects founded the village of Paynaven, the earlier Iba.[9]

  2. 1680

    The village was moved to the present site and renamed Iba.[9]

  3. 15 October 1903

    Act No. 945 of 15 October 1903 reduced Zambales from twenty-five municipalities to fifteen. Iba was kept and took over the territory of Palauig.[12]

  4. July 1909 (effective 1 January 1910)

    Executive Order No. 57 separated Palauig from Iba, so Iba shrank back to its pre-1903 territory.[13]

Nearby

Iba shares a border with Botolan, Palauig and San Jose.
