A question to Iranian diaspora...

As an Iranian who has never lived outside of Iran, I always wonder what percentage or how many Iranians living abroad are religious. By "religious," I don’t necessarily mean Islam or even sects associated with Islam, but any kind of religion or faith, including Buddhism or Mormonism. Although religiosity is generally declining, we still see many Middle Eastern nationalities living in Europe and the U.S. who maintain a religious atmosphere among themselves but about iranians idk. Please share your experiences and thoughts on this.
