File:Predominant Western World Major Christian Branch by country.svg

English: A Western country is coloured either Orthodox, Protestant, or Catholic, if it counts more than 50% more members than any second.

Note: in fact, Christianity is taxonomically divided in the following 6 branches: w:Church of the East, w:Oriental Orthodoxy, w:Eastern Orthodoxy, w:Roman Catholicism, w:Protestantism, and w:Restorationism. Most recent available data is used.

Data and sources used:

Australia 2011: Orthodox 2%, Protestant 28%, Catholic 25%. More recent data reports a wide Catholic predominancy, but this data doesn't account for the other many non-Anglican Protestant, and also it notes that the question on religious affiliation was optional, so I used 2011 data which reports an even context.

Belgium 2019: Orthodox 1%, Protestant 3%, Catholic 54%

Cyprus 2019: Orthodox 95%, Protestant 0%, Catholic 1%

Czech Republic 2019: Orthodox 1%, Protestant 1%, Catholic 25%

Denmark 2019: Orthodox 1%, Protestant 62%, Catholic 2%

Estonia. Data is contradictory: in 2000 national data reports an even context, while in 2011 some report an Orthodox predominancy and some a Protestant (evidently because of renewed nearby Russian immigration into the EU). Most recent data by the EU shows a wide Orthodox predominancy, but given the 2011 contradictions I left it gray.
