Climate

Type I has a dry season from November to April and a wet one for the rest of the year; Type II has no dry season, with the most rain from December to February; Type III has a short dry season; Type IV has rain spread through the year.More in the glossary

Type I[34]

Two seasons: dry from November to April, wet for the rest of the year, with the heaviest rain from June to September.

About 9 of every 100 people in La Union lived below the poverty line in 2023 (8.7%)[22]

The PSA's survey puts it between 6.2% and 11.3%, with 95% confidence. The poverty line was ₱33,304 a person for the year.

The PSA notes: Those with CVs higher than 10% in 2023 poverty incidence among population should be used with caution.

Everything listed for La Union in Now

Created
Founded by the superior decree of Governor-General Antonio María Blanco, 2 March 1850, confirmed by royal order on 18 April 1854; its civil government was set up under Act No. 203, enacted 15 August 1901[9, 10, 11, 12]

How it got its name

La Union means the union. Governor-General Narciso Clavería chose the name himself for a province joining towns of Ilocos Sur and Pangasinan with rancherías of the Cordillera.[9, 10, 11]

Its story

In June 1572 Juan de Salcedo's men landed at Agoo, then part of Pangasinan, a port the Spaniards called the Port of Japan for the Japanese merchants who traded there.[10]

Its towns lay far from their capitals at Vigan and Lingayen. On 29 October 1849 Clavería proposed joining three towns of Ilocos Sur, nine of Pangasinan and the Cordillera rancherías of Benguet into one province; after 124 days of study, Governor-General Antonio María Blanco founded it by decree on 2 March 1850, with San Fernando as its capital.[9, 10]

Queen Isabel II confirmed the decree by royal order on 18 April 1854. The province keeps 2 March as its founding anniversary; the 173rd fell in 2023.[9, 10, 11, 13]

On 22 May 1898 the killing of the friar Mariano García of Santo Tomas set off the revolution in the province, and General Manuel Tinio's forces drove out the Spaniards.[10]

Act No. 203 set up its civil government on 15 August 1901, with Joaquín Ortega as its first civil governor, and in 1903 its fifteen towns were merged into twelve. On 4 January 1945 Filipino and American soldiers took the Baroro Bridge at Bacnotan, opening the way to the liberation of La Union.[9, 10, 12, 14]
