The change in the family units
In the past, it’s common to see one big family that is made up of a few generations including parents, children, grandparents and grandchildren living together in the same home or in the same neighborhood. As children grow up, they sometimes go to good schools far away in other towns. As young people receive higher education, many of them seek good jobs outside of their hometown. example, parents sent their children to famous schools in capital cities. Young people left their small hometowns to work in big cities.
But this is not only the cause of smaller family groups. Many couples have fewer children these days. Some prefer a single child or even on children at all, because of economic reasons. In the future, there will be more and more families consisting of two parents with only one or two children at most or on children at all.
