Children raised by a single parent are no less happy than those living with two biological parents, a study has found.
Researchers from NatCen Social Research found family composition has "no significant effect" on the happiness of children. Rather, it is the quality of relationships at home which are most strongly linked to a child's well-being.
The results challenge the popular conception that children in two-parent families are more likely to be stable and content than those raised in "broken" homes.
Researchers analysed data from the Millennium Cohort Study, which was made up of 12,877 children aged seven, in 2008, from across the UK. The children came from three family types: those living with two biological parents; those living with a step-parent and a biological parent; and those with just a single parent.
The seven-year-olds were asked the question: "How often do you feel happy?"
