There are worrying details of the U.S census on the increasing number of children that are raised by their grandparents: 2, 4 million venerable old people are responsible for the raising of 4, 4 million grandchildren.
The weekly magazine The Economist reports that a third of these grandparents (heads of household) had not completed high school and 62% of them had not went to the university. The American Academy of Child and Adolescent Psychiatry explains the causes: increase in single-parent families, high divorce rate, teenage pregnancies, incompetence of parents in prison, alcoholism, drug abuse and domestic violence.
Grandparents play a very important role in the education of grandchildren because they are models of behavior. They transmit rules, attitudes, and moral values», while receive «the company and the love of their grandchildren.»
