Pangasinan, which is historically and geographically part of the Central Luzon Region, is made politically part of the Ilocos Region (Region I) in the gerrymandering of the Philippines by Ferdinand Marcos, despite the fact that Pangasinan has its distinct primary language, which is Pangasinan. The political classification of Pangasinan as part of the Ilocos Region has generated confusion among some Filipinos that the residents of Pangasinan are Ilocanos, even though Ilocanos only constitute a significant minority in the province. Pangasinan has a distinct primary language, ethnic group and culture, its economy is bigger than the predominantly Ilocano provinces of Ilocos Norte, Ilocos Sur and La Union and its population is more than 50 percent of the population of Region 1.
