Reading it
Population is the count as of July 1, 2024, the reference date of the 2024 Census of Population. The 2020 figure is from the census before it, so the change covers 4 years rather than a single year.
Density is the census population over the land area on record. It is a flat average: a coastal town whose people all live along one road will read the same as one spread evenly across its hills.
Average barangay population divides the total across every barangay equally, which no municipality actually does — it is useful for comparing units, not for describing one.

26Western Wao (Pob.)no roster
DILG’s directory has no roster on file for Western Wao (Pob.). That is a gap in the directory, not a barangay without officials — ask DILG or the municipal hall.
Each barangay is its own local government unit with an elected punong barangay and council. The code beside a name is its PSGC identifier — the number every national record uses for that barangay.
Officials are from DILG’s Barangay Officials Directory as it stood on 2026-09-26; 25 of these 26 barangays have an entry in it. DILG publishes no term alongside the names and updates the directory as barangays report, so a name here is the last one filed rather than a guarantee of who holds the office today. DILG’s directory also carries contact details, which are not repeated here.

“Held” marks a term whose office-holder shares a surname with the term before it. Surnames, not people — a seat passing between relatives reads the same here as one person re-elected, and in most of these towns it is the more common of the two.

What a municipality is responsible for.
These services are devolved to this level by the Bangsamoro Local Governance Code, so they describe what Waois mandated to provide — not an inventory of what its offices currently run. For opening hours and requirements, the unit’s own hall is the source.
Health
01- Rural health units, health centers and barangay health stations
- Primary health care, maternal and child care, communicable disease control
- Purchase of medicines and medical supplies
Social services
02- Day care centers and child and family welfare
- Programs for women, the elderly and persons with disabilities
- Nutrition, family planning and community-based rehabilitation
Infrastructure and public works
03- Municipal or city roads, bridges, drainage and flood control
- School buildings, health centers, public markets and slaughterhouses
- Water supply systems and communal irrigation
- Sites for the police and fire stations and the municipal jail
Permits, records and regulation
04- Business permits and licensing
- Building permits and zoning enforcement
- Civil registry — birth, marriage and death certificates
- Real property assessment and tax collection
- Reclassifying farmland — capped at 15% of the town’s agricultural land, 10% or 5% in smaller classes
Agriculture, environment and safety
05- Agricultural extension, seed farms and fisheries
- Solid waste collection and disposal
- Community-based forestry projects
- Fire and police coordination, and disaster risk reduction
And at the barangay
Frontline services
- Barangay clearance and certificates of residency and indigency
- Barangay health station and day care center
- Katarungang Pambarangay — a lupon of 10 to 20 members mediates disputes before they reach court
Community
- Barangay tanod and peace and order at street level — one tanod per 200 residents, 30 at most
- Maintenance of barangay roads, footpaths and water supply
- Solid waste segregation at source
- Agricultural support — planting materials and farm produce collection and buying stations
Money it handles
- A tax of up to 1% on stores with gross sales under ₱50,000 in a city or ₱30,000 in a municipality
- Its share of the real property tax — 25% of what the province collects on property in it
- 10% of its general fund set aside for the Sangguniang Kabataan
- Its own annual budget, reviewed by the city or municipal council within 90 days
And what you pay it.
These are the ceilings the Bangsamoro Local Governance Code and its implementing rules set on what a municipality and its barangays may charge, with the deadlines that go with them. Wao sets its own rates by ordinance and may charge less, so treat these as the most it can be rather than the bill — the hall has the ordinance.

About these figures
Structure from the Philippine Standard Geographic Code; population and land area from Wikidata, which carries PSA’s census figures with their census dates. Population is the 2024 Census of Population. Elected officials are the winners in COMELEC’s 2025 Certificates of Canvass, holding office to June 30, 2028.
Sulu is excluded: the Supreme Court removed it from BARMM. PSA census totals that still count Sulu will therefore be larger than the totals here. Cotabato City is listed as an area of its own, though PSA files it inside Maguindanao del Norte — the provincial figure here has the city taken out of it so the two are not counted twice. Province land area is the province’s own published figure, never a sum of its municipalities: Philippine municipal areas are self-reported and overlap, so they do not add up to the province they sit in. A blank is a fact about the record, not a zero.
A dash means the record has no figure — not a zero. Boundaries and office-holders change; where this differs from an official page, the official page is right.
