Are Germans Catholic or Protestant?
Unlike most European countries, which tend to be either largely Catholic (e.g. Ireland, Spain) or largely Protestant (e.g. Sweden, UK), German Christians are split almost evenly.
Around half of Germany's Christians are from the Evangelical Church of Germany (a combination of Protestant religions including Lutheranism and Protestant Calvinism) and half are Roman Catholic. Around 2% of the country practice other Christian religions - mainly Orthodoxy, including both Eastern and Oriental Orthodoxy.
Which part of Germany is Catholic?
Although you will find followers of both Catholicism and Protestantism in all regions of Germany, the religions are more distinct in certain regions. As a rule, you will encounter more Catholics in the South and West of the country, including Bavaria, Rhineland, Westphalia and Saarland. In the North and East of the country, more of the population identify as protestant.
