Besides, there also exist 62 administrative districts, officially called "Administrative Units" (upravne enote), which are not a body of local self-government, but territorial sub-units of government administration.

The Administrative Units are named after their capital, and are headed by a Head of the Unit (načelnik upravne enote), appointed by the Minister of Public Administration.

Each municipality is headed by a Mayor (župan), elected every 4 years by popular vote, and a Municipal Council (občinski svet).

In the majority of the municipalities, the municipal council is elected through the system of proportional representation; only few smaller municipalities use the plurality voting system.

In the urban municipalities, the municipal councils are called Town (or City) Councils.

Every municipality also has a Head of the Municipal Administration (načelnik občinske uprave), appointed by the Mayor, who is responsible for the functioning of the local administration.[88]

Despite the lack of any intermediate unit between the municipalities and the State, regional identity is strong in Slovenia.

Ljubljana was historically the administrative center of Carniola.

However, from the mid-19th century onward, it has not been considered part of any of the three subdivisions of Carniola (Upper, Lower and Inner Carniola).Nowadays, it is not considered part of any of the traditional historical regions of Slovenia.

For statistical reasons, Slovenia is also subdivided into 12 statistical regions, which have no administrative function. These are further subdivided into two macroregions for the purpose of the Regional policy of the European Union.

These two macroregions are:

East Slovenia (Vzhodna Slovenija – SI01), which groups the regions of Pomurska, Podravska, Koroška, Savinjska, Zasavska, Spodnjeposavska, Jugovzhodna Slovenija and Notranjsko-kraška.

West Slovenia (Zahodna Slovenija – SI02), which groups the regions of Osrednjeslovenska, Gorenjska, Goriška and Obalno-kraška.
