Very safe, and welcoming community of people! It is one of the safest cities in the world, and it really shows. Everyone is very friendly, and the schools are top notch for your kids.
I like the diverse atmosphere that Naperville provides. There is so many friendly faces as one walks down the street.
The area is very diverse due to the city being relatively close to Chicago. Although the area is very family friendly and safe, the overall cost of living is absolutely ridiculous. As a person making $72,000/ year, I considered it quiet expensive place to live. Unless you are making over $100,000/year I recommend living in other nearby cities such as Joliet, Schamburg, and etc... They offer just as nice of schools, housing, and other great aspects at the same level or better than Naperville.
