Which Christian denominations have significant communities in Hungary?

Hungary does not have an official religion and guarantees religious freedom for its citizens. Several Christian denominations maintain significant communities within the country:1

• Roman Catholicism: This is the largest religious group, with more than one-third of the population identifying as Roman Catholic. These communities are primarily concentrated in the western and northern regions of Hungary.1
• Calvinism: About one-tenth of the population belongs to the Reformed Church in Hungary, which is the second-largest religious body in the country. These communities are most heavily concentrated in eastern Hungary.21
• Lutheranism: Lutherans represent the next most significant minority faith in the country.1
• Other Denominations: Relatively smaller groups belong to various other Christian traditions, including Eastern Orthodox churches, Greek or Byzantine Catholics, and Unitarians.1

It is important to note that nominal membership in a religious denomination does not necessarily reflect active participation or personal spiritual belief.1
