Several colleges in Michigan have added courses on the topic of suburbs - joining a trend that has spread across the country in higher education. Wayne State University officials are thinking about adding another. \"It\'s an enormously important and rich field,\" said Peter Eisinger, a professor who has taught a political science course on the suburbs at Wayne State. The new college courses on suburbia focus on the demographics and socio-economic features of its populace and how it changed over 40 years. Students who took the Suburban Paradise course at Wayne State said they were surprised to learn their suburban hometowns were more complicated than they thought. \"I learned how big a part of the American landscape they are,\" said Jason Booza, 28, who took the Wayne State class as a graduate student. \"Now it\'s the suburbs that dominate everything.\" Booza, who works at the university's Center for Urban Studies, said he was intrigued by the suburban class because it was so different from all the others in his major, political science.
