Christianity is the predominant religion in Slovakia. The majority (62%) of Slovaks belong to the Latin Church of the Catholic Church; with the addition of a further 4% of Greek (Byzantine) Catholics, all Catholics account for 66%. Members of a Protestant denomination, mainly Lutheran or Reformed, account for 9%. Members of other churches, including those non-registered, account for 1.1% of the population. The Eastern Orthodox Christians are mostly found in Ruthenian (Rusyns) areas. The Catholic Church divides the country into 8 dioceses including 3 archdioceses in two different provinces. The Slovak Greek Catholic Church is a Metropolitan sui iuris Church with three Eparchies in Slovakia and one in Canada. Generally about one third of church members regularly attend church services. The religious situation is dramatically different from that in the neighbouring Czech Republic, which is notable for its atheist or irreligious majority.
Other religions practiced in Slovakia include Bahá'í Faith, Hinduism, Islam, and Judaism. There are 18 registered churches and religions. There were an estimated 0.2% Muslims in Slovakia in 2010. While the country had an estimated pre-World War II Jewish population of 90,000, only about 2,300 Jews remain today.
In 2016, Slovak parliament passed a new bill that will obstruct Islam and other religious organisations from becoming state-recognized religion by doubling the minimum followers threshold from 25,000 to 50,000. The law passed by a two-third majority at the parliament. In 2010, there were an estimated 5,000 Muslims in Slovakia representing less than 0.1% of the country's population.
