Methodology & Data Sources

Coverage

Barangay Directory catalogs every administrative barangay in the Republic of the Philippines — 42,010 barangays across 1,642 cities and municipalities, 82 provinces, and 18 administrative regions. Counts reflect the latest official Philippine government open-data release (as of 31 March 2026). Every barangay has a dedicated, indexable page whether or not we currently hold verified contact details for it.

Data sources

• Geographic hierarchy and administrative codes — sourced from official Philippine government open data portals. Authoritative.
• Population figures (2024 POPCEN, 2020 CPH, and 2015) — sourced from official Philippine Statistics Authority publications. The 2024 Census of Population was declared official by presidential proclamation in July 2025 and is the headline figure shown on every barangay, city, province, and region page. Older 2020 and 2015 figures are kept where useful for historical comparison.
• Urban / rural classification — from the same census release. Definitions follow the official classification criteria for Philippine barangays.
• Barangay hall addresses, phone numbers, officials — compiled from public government directories, local government unit websites, and verified user submissions. Verification status varies per record and is indicated on each page.

Verification

Each barangay page displays a ✓ Verified badge when contact details have been confirmed through at least one authoritative source or corroborated through multiple independent sources. Unverified entries are clearly marked as such and invite users to submit corrections.

Known data quality limitations

The per-barangay population dataset we use is derived from official PSA census tables. While the bulk of the data is accurate, a small number of records contain clear artefacts — typically barangays showing implausible population drops between census periods. These appear to be upstream data entry errors rather than genuine depopulation.

On our ranking pages we apply a plausibility filter to the “smallest barangays” list specifically: any barangay with a 2024 POPCEN population under 50 or with a drop of more than 75% from its 2020 baseline is excluded. This removes the obviously-broken rows while preserving genuinely small rural barangays. The “most populous” and “fastest growing” rankings do not need this filter because their top entries use larger numbers where data quality is reliable.

Individual barangay pages show the raw 2015, 2020, and 2024 figures as published in the source data. If you find an error on a specific page, please submit a correction via the contact form and we will investigate.

2024 POPCEN per-barangay figures

The 2024 Census of Population (POPCEN) was declared official by presidential proclamation on 11 July 2025. The per-barangay breakdown is now imported and shown on every barangay, city, province, and region page. Where a barangay does not yet have a 2024 figure (a small number of newly reorganised areas), the page falls back to the most recent available census year so visitors always see real numbers rather than gaps.

Update cadence

• Geographic and population data: updated when new official Philippine census figures are released.
• Officials: refreshed after each Barangay and SK Election. The next BSKE is scheduled for Monday, November 2, 2026.
• Contact details and addresses: continuously updated through user submissions and periodic automated sweeps.
• National population headline statistic: refreshed daily from open data feeds.

Corrections

If you spot an error on any barangay page, use the submission form on that page. Submissions from verified barangay officials are prioritized. We do not collect personal information about residents — only public administrative data about the barangay as a local government unit.
