In Austria, Christianity is the dominant and most popular religion of the people who follow a religion. When broken down, Catholicism is probably the most popular with over half of the people in Austria practicing this denomination. The other most popular denominations under the category of Christianity would be Eastern Orthodoxy and Protestantism. However, if added these two denominations together, they only equal to a little over ten percent of the Austria population.
The other religions include Islam and Buddhism with about a little over eight percent of the people practicing these religions. The remainder twenty-two percent do not practice a religion or they practice another type of religion in Austria. Therefore, if you run into someone in Austria, they are probably Catholic based on the statistics.
