It's worth noting that religion is not a demographic category that explicitly factors into admissions or collected. Students are not required to disclose their religion (sexuality for that matter as well). Those figures are collected through various student surveys and may not fully representative. Also international students are counted separately from the race/ethnicity categories. This is due to how the government classifies and collects information about race and ethnicity (see IPEDS definitions below). https://nces.ed.gov/ipeds/report-your-data/race-ethnicity-definitions https://nces.ed.gov/ipeds/report-your-data/race-ethnicity-de... I used to work at Harvard as an institutional research analyst. I actually submitted the final reports (institutional demographics and other stats) to US Department of Education. If anyone is curious, a large portion of the aggregate demographic statistics is open and available to the public: https://nces.ed.gov/ipeds/use-the-data https://nces.ed.gov/ipeds/use-the-data
