The Statistical Yearbook of Ljubljana is a publication with a rich tradition as it has been published annually since 1966 and provides comprehensive statistical data on all the main areas of socio-economic activity in Ljubljana. It includes data collected by the Statistical Office of the Republic of Slovenia as well as data from authorities and organizations authorized to collect the data.

The Statistical Yearbook of Ljubljana presents data which territorially refer to the territory of the Municipality of Ljubljana with boundaries as they were set in 1995 with the Establishment of Municipalities and Municipal Boundaries Act (Official Gazette of the Republic of Slovenia, no. 108/06 - official consolidated text, 9/11).Up to 1995, the City of Ljubljana was made up of 5 municipalities, namely: Ljubljana Bežigrad, Ljubljana Centre, Ljubljana Moste - Polje, Ljubljana Šiška and Ljubljana Vič - Rudnik. In 1995, there was a new organisation in the field of local self-government. The City of Ljubljana was restructured into the Municipality of Ljubljana and nine suburban municipalities: Brezovica, Dobrova - Polhov Gradec, Horjul, Dol pri Ljubljani, Ig, Medvode, Škofljica, Velike Lašče and Vodice.

The Municipality of Ljubljana combines 38 settlements, of which Ljubljana is the largest one. When the data refer to the settlement of Ljubljana, the latter is specifically marked in the Statistical Yearbook.

On the territory of the ten municipalities which were restructured in 1995, the Administrative Unit of Ljubljana still operates organizationally with its branche offices Bežigrad, Centre, Moste - Polje, Šiška and Vič - Rudnik. The Administrative Unit of Ljubljana is territorially completely covered with the ten municipalities - the Municipality of Ljubljana and the nine suburban ones.

The reorganisation of the municipalities in 1995 represented a quite complex organizational shift, making it difficult for the relevant services to be able to keep up with the data in their entirety. A part of data can thus still be monitored according to the old principle of division to former five municipalities of the City of Ljubljana or according to the scope of the territory of the Administrative Unit of Ljubljana. The data collected in such a manner are labelled with the abbreviation UEL (Slovenian abbreviation for the Administrative Unit of Ljubljana) and include the territorial area of all ten new established municipalities (the Municipality of Ljubljana and the nine suburban ones) as a whole, and are comparable to the data of the previous years for the City of Ljubljana before the year 1995.

Due to an increased interest in data on the area of the Ljubljana Urban Region, we began publishing some data for this area which consists of 26 municipalities, namely: Borovnica, Brezovica, Dobrepolje, Dobrova - Polhov Gradec, Dol pri Ljubljani, Domžale, Grosuplje, Horjul, Ig, Ivančna Gorica, Kamnik, Komenda, Lithium, Ljubljana, Log - Dragomer, Logatec Lukovica, Medvode, Mengeš, Moravče, Škofljica, Šmartno pri Litiji, Trzin, Velike Lašče, Vodice and Vrhnika. The surface area of this region in the statistical classification regions completely matches that of the Central Slovenia statistical region (Slovenian: Osrednje slovenska statistična regija).
