Beyond these, the national government groups provinces and independent cities into regions, e.g. Metro Manila or Region VI. The President has the prerogative to create, abolish and determine the composition of regions, which is done so most often in consultation with the local government units affected, with the exception of autonomous regions, where the residents of the local government units have to ratify in a plebiscite their inclusion in such a setup.
Further, also for similar administrative purposes, a barangay may be sub-divided into either sitios or puroks. Neither the national government's regions nor a barangay's sitios or puroks have elected leaders or government branches.
Other divisions exist for specific narrower purposes:
The Philippines is divided into provinces and independent cities. Provinces in turn are divided into component cities and municipalities. All independent cities, component cities and municipalities are divided into barangays. All these (provinces, independent and component cities, municipalities, and barangays) elect their own legislatures and executives and are called collectively "local government units". There is also a single autonomous region, the Automous Region of Muslim Mindanao (ARMM), which is composed of provinces and independent cities and has its own elected government.
Each province is headed by a governor. Its legislative body is the Sangguniang Panlalawigan composed of the different members from Sanggunian districts, which in most cases are contiguous to the congressional districts.
Regions, aside from having provinces may also have independent cities. Independent cities, classified either as highly urbanized or independent component cities, are cities which are not under the jurisdiction of a province. These cities are not administered by their mother provinces, do not share their tax revenues with the province, and in most cases their residents are not eligible to elect or be elected to provincial offices.
Cities that are politically a part of a province are called component cities. The voters in these cities are allowed to vote and run for positions in the provincial government.
Municipalities are always components of a province, except Pateros, Metro Manila, which is independent.
Cities and municipalities are headed by a mayor. The legislative arm of these units are the Sangguniang Panlungsod for cities and Sangguniang Bayan for municipalities, which are composed of councilors elected at-large or in some cases, by Sanggunian district.
Cities (both component and independent ones) and municipalities are further divided into barangays. The barangay is the smallest political unit, and is often loosely anglicised as "village". In some populous cities, barangays are grouped into zones and/or into districts for administrative purposes. In rural areas, sitios or puroks are the preferred ways of subdividing barangays for administrative purposes. Each barangay is headed by a Barangay captain (Filipino: Punong Barangay)
Below barangays are smaller communities known as sitios and puróks, and are not found in all baranagays. Sitios and puróks are most common in less-populated, rural barangays where human settlement is de facto polycentric, that is, composed of multiple population enclaves spread throughout a wide area, surrounded or separated by farmland, undeveloped mountainside, and water (as is the case of barangays encompassing different islands).
Their leadership is not a recognised Local Government Unit and thus its officials are not elected in regular general elections.
Regions are administrative groupings of provinces. All but one region do not have political power, but merely serve as administrative groupings of provinces. The Autonomous Region in Muslim Mindanao has political power, and is headed by a regional governor. If the Cordillera Administrative Region becomes autonomous, it too, would have political power.
All but one region is divided into provinces. Metro Manila (the National Capital Region) is not divided into provinces, but instead is divided directly into cities and municipalities. The cities and municipalities of Metro Manila are grouped together into non-functional districts for administrative purposes.
For the purpose of electing representatives to the Philippine House of Representatives, the country is divided into "legislative districts". Each province or independent city has at least one representative. If the population is great enough, they may have two or more. The borders of the district are redrawn, known as redistricting, by the passage of an act of Congress, and signed by the president, a process that only happens rarely and only for a limited area.
If a province or a city is composed of only one legislative district, it said to be the lone district (for example, the "Lone district of Muntinlupa City").
The Philippines is divided into thirteen judicial regions, for the purpose of organizing the judiciary. The judicial regions still reflect the original regional configuration introduced by President Ferdinand Marcos during his rule, except for the transfer of Aurora to the third judicial region.
The various executive departments has also divided the country into their own respective districts. The Department of Public Works and Highways and the Bureau of Internal Revenue, for example, divide the country into several "engineering" or "revenue" districts.
The Philippines is broadly divided into three regions: Luzon, Visayas and Mindanao. These regions are reflected in the name of the national government's formal regions (e.g. Western Visayas) but they have no administrative bodies, either elected or appointed.
