The rising age of marriage/family creation and particularly the increasing age of having children (Diagrams 5.5 and 5.6) are bound to affect the investment/savings balance for households. Note the increasing number of women having children in their forties. Back in the 1970s and 1980s, most people would marry in their early twenties, have had most of their children by age 35 and have expected their children to have left home by their late forties.
