Yes, I know, but its like calling Chicago a college town because it's got DePaul, Loyola, UIC, etc. But it does not make it a college town just because it has many colleges.
Des Moines is a decent size city, not dominated by Drake and its campus. Cedar Rapids is not dominated by Coe College.
On the other hand, Cedar Falls, Ames, and Iowa City are dominated by the Universities in those towns. Most people that live in those towns either work for the University or go to school there.
