About this dataset

United Nations standardized second-level administrative boundaries with ISO codes, managed by the SALB program for consistent international comparison.

The UN SALB (Second Administrative Level Boundaries) program provides standardized second-level administrative boundary datasets for UN member states. Each boundary is coded with ISO 3166-1 and ISO 3166-2 identifiers, enabling consistent cross-country comparison of subnational units. The dataset is curated by the UN Geospatial Information Section and is designed for international development, statistical reporting, and policy analysis.

FAQ

How is UN SALB different from GADM?

UN SALB focuses specifically on second-level administrative boundaries with official ISO 3166-2 coding and UN endorsement, while GADM provides deeper administrative levels but is a research product rather than an officially sanctioned dataset.

Does UN SALB cover all countries?

UN SALB aims to cover all UN member states, but coverage varies. Some countries have complete second-level data while others are still being processed. Check the catalog on unsalb.org for current availability.
