Could you elaborate on the religious affiliation of students at Brigham Young University (BYU)? Specifically, how prevalent is Mormonism among the student population? Are there any statistics or estimates available that indicate the percentage of Mormon students at BYU, and if so, what are they? Is the religious makeup of the university reflective of the surrounding community or does it differ significantly? Additionally, does the university promote religious diversity and inclusivity among its student body?
