Colleges can have a big impact on the lives of citizens who live in the cities where their college is located. Sometimes this can be a bad thing. Imagine a small town trying to accommodate the 10,000 students who attend its college: traffic jams, more litter, crowded public places, etc.
Fortunately, the opposite can also be true. The presence of a college in a town can be very beneficial. Colleges can revitalize an area, increase community service volunteering, and serve as a cultural renewal.
