Life & Economy

About 14 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
14.0% of people[22]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 14 of every 100 people in Ilagan City lived below the poverty line in 2021 (14.0%)[22]

Everything listed for Ilagan City in Now

Official name
City of Ilagan[4]
Created
Republic Act No. 10169, approved on 21 June 2012, converted the Municipality of Ilagan into a component city of Isabela, the City of Ilagan. The city was to gain corporate existence once voters ratified it in a plebiscite.[9]

Its story

Under Act No. 941 of 12 October 1903 the municipality of Ilagan took in the neighbouring municipality of Palanan, and its seat stayed at Ilagan.[10]

Act No. 1466, dated 19 March 1906, separated Palanan from Ilagan again, so that Ilagan went back to the territory it had before Act 941.[11]

On 3 December 1965 Executive Order No. 212 formed the municipality of Quirino from barrios of Ilagan, Roxas and Gamu. Eight barrios came from Ilagan, among them Santa Lucia, Santiago and Vintar.[12]

A charter act of 1998, Republic Act No. 8474, had already declared Ilagan a component city. The city that exists today rests on Republic Act No. 10169 of 2012, and the province lists Ilagan as an independent city from 2012.[13, 14]
