BALTIMORE -- A new survey says the number of public college presidents earning over $1 million more than doubled from the year before.

The study by The Chronicle of Higher Education says nine college presidents earned more than $1 million in total compensation in the 2012-2013 fiscal year, compared to just four in the previous year.

Public college presidents first exceeded the $1 million total compensation mark in 2004.

Gordon Gee topped the list, earning $6.1 million at the helm of Ohio State University. Gee resigned that post last year after making comments about Roman Catholics, the University of Notre Dame and Southeastern Conference schools. He is now president of West Virginia University.

The study takes into account base salary, bonuses, deferred pay, retirement and severance pay.
