" Chicago's enormous visibility on the global stage, should it be chosen to host the Games in 2016, would have a direct impact on the city's tourism industry, educational institutions, cultural institutions, business community and neighborhoods," says a release from 2016 Chicago.
The study also projects increased participation in sports in the United States, particularly the Midwest, if Chicago were to host the Games.
Chicago 2016 said the study took into account the projected $1.4 billion it would cost to host the Games.
Cook County is expected to net $5.5 billion. The six collar counties would get an injection estimated at $1.8 billion and the remainder of Illinois would see another $1.5 billion in new economic activity, the study says.
