Demographics
Most professors in the U.S. are male, liberal (in the American political sense), and upper middle class. A slight majority of professors ranked among the top 15% of wage earners, in 2005.
According to a study by Robert Lichter, a professor at George Mason University, "The vast majority of professors in the United States identify themselves as liberal, and registered Democrats commonly outnumber registered Republicans." This varies across departments. In terms of education, the vast majority hold doctorate degrees. Professors at community colleges may only have a master's degree while those at four-year institutions are commonly required to hold a doctorate degree.
