FWIW, the Common Data Set input for the 2023-2024 year shows Greek life actually reducing. In Fall 2022, they reported 20% in fraternities and 37% in sororities. In Fall 2023, they reported 21% in fraternities and 24% in sororities. I don’t know why the sorority number has gone down so much. It’s historically been in the mid to upper 30s for many years, so maybe there are changes afoot.
