Answer:
it is very similar to it's neighbors
Explanation:
Most of Saudi Arabia's population has Islam as its official religion, although other religions are permitted and celebrated in the country, but with less popularity.
The neighboring countries to Saudi Arabia are Yemen, Qatar, the United Arab Emirates, Oman, Iraq and Jordan, which also present Islam as an official religion and have other religions that are less popular.
This makes us say that the religious composition of Saudi Arabia is very similar to the religious composition of the countries neighboring it.
