OSM Tag History
The
admin_level
=*
key describes the administrative level of a feature within a subdivision hierarchy. It is used on the borders of territorial entities together with appropriate
boundary
=*
tag, primarily (but not exclusively) for political entities (
boundary
administrative
– e.g. country, state, municipality). Due to cultural and political differences, admin levels of different countries only correspond approximately to each other. For example, an
admin_level
entity in one
admin_level
(sub-national jurisdiction) of a country (
admin_level
) isn't exactly the same sort of entity as an
admin_level
entity in another sub-national jurisdiction, even though they are in the same country. This is because laws (constitutions, legal traditions...) in each sub-national jurisdiction can and do differ from one other, even in the larger sphere of the national jurisdiction.
It is also used with other types of objects that are associated with government entities. For example, see
Key:capital
Rationale
admin_level
through
admin_level
10
allow for different administrative subdivision schemes to be handled in a consistent way by data consumers. The use of a numbering scheme rather than words for the values helps avoid confusion due to different terminology used in different countries. One country may describe the highest sub-national division as a "state", and another a "province". By using
admin_level
for both of these it is more clear.
Additionally, when used with
boundary
administrative
admin_level
=*
allows for a standard rendering scheme between countries with different levels of hierarchies.
Data consumers should take care when interpreting values of this key. While
admin_level
is almost always a de-facto independent country, and
admin_level
is usually equivalent to a "province", higher values vary in meaning between countries. A data consumer looking for municipalities corresponding to "city", "town" or "village" boundaries will find these tagged anywhere from
admin_level
(e.g.
Berlin
Berlin
) to
admin_level
10
(e.g.
Cheddar, UK
Cheddar, UK
).
See
country-specific values
for the appropriate numeric
admin_level
=*
values.
Usage
admin_level
=*
is added to a relation or way which is typically also tagged with:
boundary
=*
(94% of "administrative" boundaries or 80% of all boundaries as of 3/2024)
Or sometimes to a node or way which is also tagged with:
office
government
government
=*
(5% of these have the admin_level tag as of 3/2024)
amenity
courthouse
(below the taginfo threshold as of 3/2024)
In addition to the direct usage of this tag with the keys above, the
numeric values
used by
admin_level
=*
are also used for tags:
capital
=*
– usually as
admin_centre
of an
admin_level
=*
tagged relation with the same number.
