The list is somewhat deceptive because it strongly penalizes towns with large retail developments. For instance, Paramus scored worse than Irvington. Now, if anyone actually believes that Irvington is a quieter and safer town than Paramus, you've got rocks in your head.
Wayne and Eatontown also have abysmal scores, and both have major malls. Hackensack would actually score higher, if not for our heavy retail.
