Ilocos Norte in the context of "Ilocano language"

The barangay (/bɑːrɑːŋˈɡaɪ/; abbreviated as Brgy. or Bgy.), historically known as the barrio, is the smallest administrative division in the Philippines. Named after the precolonial polities of the same name, modern barangays are political subdivisions of cities and municipalities, and are analogous to villages, districts, neighborhoods, suburbs, or boroughs. The term barangay is derived from balangay, a type of boat used by Austronesian peoples when they migrated to the Philippines.

All cities, including independent cities, and municipalities in the Philippines are politically subdivided into barangays, with the exception of the municipalities of Adams in Ilocos Norte and Kalayaan in Palawan, each of which contains only one barangay. Barangays are sometimes informally subdivided into smaller areas called purok (English: "zone"), or barangay zones consisting of clusters of houses for organizational purposes, and sitios, which are territorial enclaves—usually rural—located far from the poblacion. As of January 2025, there are 42,011 barangays throughout the country.

The Ilocos Region (Ilocano: Rehion/Deppaar ti Ilocos; Pangasinan: Rehiyon na Ilocos; Tagalog: Rehiyon ng Ilocos), designated as Region I, is an administrative region of the Philippines. Located in the northwestern section of Luzon, it is bordered by the Cordillera Administrative Region to the east, the Cagayan Valley to the northeast and southeast, Central Luzon to the south, and the South China Sea to the west. The region comprises four provinces: Ilocos Norte, Ilocos Sur, La Union, and Pangasinan, along with one independent-component city, Dagupan City. The regional center is the city of San Fernando in La Union, which serves as the administrative hub of the region. The largest settlement in terms of population is San Carlos City in Pangasinan.

The 2020 Philippine Statistics Authority census reported that the ethnolinguistic group composition of the region is predominantly made up of Ilocanos (58.3%), followed by Pangasinans (29.7%), Tagalogs (4.1%), and various Cordilleran (Igorot) indigenous groups.

Ilocos Sur (lit. 'South Ilocos'), officially the Province of Ilocos Sur (Ilocano: Probinsia ti Ilocos Sur; Tagalog: Lalawigan ng Ilocos Sur), is a province in the Philippines located in the Ilocos Region in Luzon.

Ilocos Sur is bordered by Ilocos Norte and Abra to the north, Mountain Province to the east, La Union and Benguet to the south and the South China Sea to the west.

Ilocos Sur was established in 1818 when the province of Ilocos was split into two: the north (now Ilocos Norte) and the south (Ilocos Sur). At that time, it included parts of Abra and the upper half of present-day La Unión. The current boundaries of the province set in March 1917 by virtue of Act No. 2683.

Cagayan (/kɑːɡəˈjɑːn/ kah-gə-YAHN, [kagɐˈjan]), officially the Province of Cagayan (Ilocano: Probinsia ti Cagayan; Ibanag: Provinsiya na Cagayan; Itawit: Provinsiya ya Cagayan; Isnag: Provinsia nga Cagayan; Ivatan: Provinsiya nu Cagayan; Gaddang: Provinsia na Cagayan; Filipino: Lalawigan ng Cagayan), is a province in the Philippines located in the Cagayan Valley region, covering the northeastern tip of Luzon.

Cagayan was one of the early provinces that existed during the Spanish colonial period.

The former capital was Nueva Segovia, which also served as the seat of the Diocese of Nueva Segovia.
