A barangay (Brgy. or Bgy.; Filipino: baranggay, [baɾaŋˈɡaj]; also pronounced the same in Spanish), formerly called barrio, is the smallest administrative division in the Philippines and is the native Filipino term for a village, district or ward. In colloquial usage, the term often refers to an inner city neighbourhood, a suburb or a suburban neighborhood.[1] The word barangay originated from balangay, a kind of boat used by a group of Austronesian peoples when they migrated to the Philippines.[2] Municipalities and cities are composed of barangays, and they may be further subdivided into smaller areas called puroks (English: zone), barangay zones consisting of a cluster of houses, and sitios, which are territorial enclaves—usually rural—far from the barangay center. As of June 2015, there were now 42,029 barangays throughout the Philippines.
