Catholicism is a religion that is practiced in nations all around the world. It's a division of Christianity, the largest religion globally. There are several core beliefs of Catholicism. First, Catholics believe that Jesus is the son of God. Catholics also believe that the Bible is the word of God. Catholics also use the Ten Commandments as a moral and ethical compass.
Catholics believe in Adam and Eve, and they believe that all humans are sinners because of Adam and Eve. Catholics believe that the practice of baptism removes this original sin and is necessary for salvation.
Data from the CIA Factbook and the Pew Research Center has been used to identify nations with the highest population of Catholics. When looking at the total number of Catholics in a nation, Brazil comes out on top. It is estimated that at least 112 million people in Brazil are Catholic, although this number could be as high as 126 million.
The top 10 nations with the most number of Catholics are:
- United States
- Democratic Republic of Congo
This list changes a bit when you look at the total percentage of a nation that practices Catholicism. For example, just over 800 people in Vatican City are Catholic. This seems like a small number, but it is 100% of the total population.
Over 96% of East Timor's population is Catholic. San Marino comes in third based on the percentage of Catholics at 90.5%.
Based on percentages, the top 10 nations with the highest Catholic populations are:
