Youngest cities in the United States

Business Insider recently posted an article showing where the youngest towns are in the United States. The youngest was in Kiryas Joel, New York where the average age is 11.4! This is because it is a community full of strict Hasidic Jews, who marry young and have large families. For Michigan, it comes as no surprise that the youngest city here is a college town and that is East Lansing where the average age 21.3.
