This document discusses local autonomy and local government structures in the Philippines. It defines local autonomy as self-governance under one's own laws. The Local Government Code of 1991 significantly decentralized governance by devolving powers to local government units (LGUs). The LGUs are comprised of provinces, municipalities, cities, and barangays. Provinces have the largest jurisdiction and municipalities and cities provide services at the community level. Barangays are the smallest local units.
