The two largest Metropolitan Statistical Areas (MSA) in Illinois are Chicago to the north and St Louis to the south. But the composite area formed by the MSA's of Peoria, Bloomington-Normal, Champaign, Decatur, and Springfield also form a significant metro area. The cost of doing business in our region is lower, housing is more affordable, and there are very few traffic delays. Small is beautiful.
