In contrast to its public school counterpart, Catholic urbanization has made more significant achievements in poor areas than wealthier areas. Holy Angels, for example has become one of the strongest academic institutions in the country; it serves the Kenwood, Oakland neighborhoods of South Side Chicago, Illinois, where 3 out of 4 people live in poverty and violent crime is frequent. A recent study of U.S. elementary students also finds that, regardless of demographic, students who attend Catholic schools exhibit less disruptive behavior and greater self-control than students in other private or public schools, suggesting the benefit that these kinds of environments can have for students of all backgrounds.
