Not a surprise, of course. From DetNews.com:
Michigan is the national leader in college football attendance for the 15th straight year...
Michigan averaged a record 112,252 fans for six home games. The Wolverines broke the record of 112,179 they set over eight home games in 2011. Michigan Stadium capacity is 109,901.
The SEC led the nation in total attendance by conference, also for the 15th straight year. The addition of Texas A&M and Missouri assured that would continue.
