Currently, the Philippines is divided into 81 provinces, with certain independent cities attached to them. These provinces, in turn, consist of municipalities. To facilitate administration, all provinces are grouped into 17 regions, termed as states in the Philippines.
Geographically, the names of the Philippines' regions are organized into three island groups. The central region encompasses major islands such as Bohol, Cebu, Leyte, Negros, Palawan, Panay, and Samar. The southern region, known as Mindanao, derives its name from the largest island within the area—Mindanao Island—along with the inclusion of Basilan and Siargao islands.
