The admin_level key describes the administrative level of an object within a government hierarchy. A lower level means higher in the hierarchy. Besides other this tag is used for the borders of territorial political entities (e.g. country, state, municipality) together with boundary=administrative. Due to cultural and political differences, admin levels of different countries only correspond approximately to each other.

Rationale

admin_level=1 to 10 has been introduced in order that different borders can be rendered consistently among countries (doing this based on border_type would require knowledge of their hierarchy in each country). This tag can be regarded as a property, i.e. it isn't a feature by its own but is rather used to describe a certain aspect of a feature.

Usage

The admin_level=* values are also used for the capital=* and heritage=* tags. Besides administrative boundaries, the admin_level=* tag currently has very few usage on features tagged with government=*.
