The religion distribution within the sub-region varied from country to country. However, many nations have shown that Roman Catholics and Protestants have the greatest percentage of followers because of the olden days of Europe where churches ruled supreme over the people. As time goes by and historical events past, many other religious groups have moved into the region, creating a diversity. The reason as to the stay varied, but many from the olden time came to the region to escaped religious persecution and seek freedom to practice whatever they would like.
According to the graph presented above, most of the population in Western Europe belong to the various branches of Christianity, although mainly Roman Catholics and Protestants. There are also a large handful of people that decided to be unaffiliated and/or belong to other religions mainly because of the large stream of migration and immigration in history.
