Fraternity Greek systems
 

Yesterday I did a thead listing by decade the institutions where national sororities were introduced. This is a list for fraternities. Nearly 800 institutions of higher learning now have functioning Greek systems with national fraternities. The trends and comments are about the same for fraternities as they were for sororities.

The first column represents the number of institutions in which national fraternities were introduced (or re-introduced from previous closures). The second column reflects the number of schools where national fraternities ceased to exist.
