Poblacion is the common term used for the administrative center, central, downtown, old town or central business district area of a Philippine city or municipality, which may take up the area of a single barangay or multiple barangays. It is sometimes shortened to Pob.

A barangay, historically referred to as a barrio, is the smallest administrative division in the Philippines and is the native Filipino term for a village, district, or ward. In metropolitan areas, the term often refers to an inner city neighborhood, a suburb, a suburban neighborhood, or even a borough. The word barangay originated from balangay, a type of boat used by a group of Austronesian peoples when they migrated to the Philippines.
