In France, the nuclear family is the most common life style, so aging persons are used to living alone.
Problems arise, however, when they become ill or disabled.
Very often their children have not enough place to host them in their house. On the other hand, when the house is big enough to welcome an ill or disabled, aging parent, the family is not primed to do it. Another solution is to maintain the aging parent in his or his or her own home and hire somebody to help him or her all day and sometimes all night at home. This is a really expensive alternative. A third solution is to have the aging parent in a nursing home.
