Yes, of course. Naperville is a neighbouring city of Chicago, and here are a few details about the city. Naperville is the fifth biggest city in the state of Illinois in terms of population, and lies in the metropolitan area of Chicago.

During the 1990s, the city was witnessing a fast speed of development and growth. It has been regarded as an important business hub in the state, on the lines of Chicago, and Naperville was even recognized among the best places to initiate business development, as brought out by Fortune.
