The last field census of population which gathered information on ethnic and religious affiliation was performed in 2002; these results are presented according to reports of the Slovene Statistical Office (SORS) in Table 1 below. After 2002, Slovenia has switched to register-based censuses, and there is no official data on ethnic and religious affiliation available since then. The Slovene Public Opinion and Mass Communication Research Centre (SPO) has been performing empirical researches of Slovene society since 1968. Current survey of this institution, conducted on a representative sample of population (N=2000) for 2019, includes indicator of religion; the result is presented in Table 2 below.
