Religion plays an important role in society. Despite individual views and states' laicism, religion defines many aspects of life, culture, history, and ideas. From widespread traditions to ethical stances, religion has an undoubted presence in our lives. Nevertheless, religions are given a different place and status from country to country. For instance, in some regions of the world, religious and governmental decisions go hand in hand, whereas in other countries, politics is not influenced by religious beliefs.

In terms of number of adherents, Christianity is the largest religion in the world. Over two billion people on earth identify themselves as Christian, while more than 1.5 billion individuals are Muslim, the second largest religion. Hinduism, Buddhism, Sikhism, and Judaism follow as the world's most popular religions. Nevertheless, when looking at the different groups among the global population, a large share of people do not belong to any religion.
