over 128,000 initiates. An important change was made during the 1970s that gave more autonomy to chapters in terms of membership selection. An amendment was passed wherein the unanimous vote rule to allow a college man to become a pledge was changed to allow individual chapters to decide on their own which method best suited their respective chapters. In 1973, the fraternity celebrated its 125th anniversary. The special occasion was marked by the construction of the university gates at Miami University. To date, there are nine buildings on the campus that were either constructed by Phi Delta Theta or named after members. The 1980s saw the fraternity deal with issues such as hazing, rising insurance costs, and maintenance of individual chapter operations. The unofficial theme of the 1980 convention was "Eliminate Hazing." The decade was marked by an increase of lawsuits dealing with hazing and alcohol abuse among many fraternities. To deal with this issue, Phi Delta Theta instituted a comprehensive insurance policy to protect its chapters. During the 1980s, an important aspect of the fraternity was created: Leadership consultants.

During the decade, Phi Delta Theta and many other fraternities experienced a decline in membership. The most important policy to be implemented by the fraternity during the decade was the decision made in 1997 to have all chapter facilities alcohol free by 2000. It was an initiative that was strongly pursued by the 1996–98 General Council.
