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.
