Good to see the discussion of diversity among parents (such as, a child being born to an unwed mother or a middle-aged woman who delayed having a child in favor of building a career).

The material presented is not only excellent for educators but can also be a great resource for international students. They would gain a better understanding of generational differences in the United States which could be quite different from those in their country of origin. Additionally, although many factors pertaining to the four generations have been presented there doesn't seem to be any discussion of the shift in the United States to single parent households.
