As a rule, on the website users have only access to data for Slovenia and its lower administrative units at the time of the census. In individual population censuses data were published at different territorial levels, which make direct comparability of census results at lower territorial levels impossible. Individual aggregate tables can include data for other republics of former Yugoslavia.

Publication of data collected by 1948-1971 Censuses was centralised as all data were published by the Federal Statistical Office for all republics of former Yugoslavia. Census books for 1948-1961 Censuses were published only in Serbo-Croatian, while 1971 Census books have a Slovene introduction and tables in Serbo-Croatian.

For the 1981 Census a publication entitled “Popis prebivalstva, gospodinjstev in stanovanj v SR Sloveniji 31. 3. 1981 – Končni rezultati po občinah (Rezultati raziskovanj 282)” is available as well as excel files with data by settlements, which are shown by the then 65 municipalities.

For the 1991 Census a bilingual publication entitled “Census of the Population, Households, Housings and Agricultural Holdings in the Republic of Slovenia 1991 – results by municipalities (Results of Surveys 617)” is available by topics (Population, Families, Households, Dwellings, Agricultural Holdings) as well as excel files with data by settlements by the then 62 municipalities. 1991 Census data recalculated to municipalities valid at the 2002 Census are published in the SI-STAT Data Portal.

1948-1991 Population Censuses data are available only on the Slovene version of the website.

A review of data collected by individual censuses and comments of data collected by 1948-1991 Censuses are available in a special publication entitled “Censuses in Slovenia 1948-1991 and Census 2002”.

For the 2002 Census the Statistical Office prepared a special website and 2002 census data are published also in the SI-STAT Data Portal.
