Illinois State University has released a study finding the school's Hancock Stadium provides the local economy with $4.1 million annually.

ISU researchers studied more than 60 events at the stadium in 2009 and used information from the Bloomington-Normal Area Convention and Visitors Bureau to arrive at the figure. Their report finds the money comes from people who attend football games and other events and then shop at local stores, eat at area restaurants and spend the night at hotels.

Earlier ISU released a study that found the school has a more than $850 million economic impact.

The study was released as the school tries to raise money to renovate the stadium. ISU President Al Bowman says up to $25 million is needed.
