In 2005, 1.76 million families were made up of children under 25 years of age and a lone parent, most commonly the child’s mother. Since the 1960s, the proportion of single-parent families has grown continually as a result of the increased fragility of parental unions. Only half of single mothers work full-time, despite usually contributing the greatest proportion of the household's income. Single-parent families experience more difficult and more fragile housing conditions than couples with children. They own their own home less often. A sign of the difficulties of living alone with children is the fact that 10% of these families share their home with other people, usually a parent.
