New figures show that 22 per cent of girls in care homes become teenage mothers and that 1 in 10 of those have their children taken in to care.
There have been calls to end the ‘cycle of disadvantage’ by local authorities offering more support and encouragement to young mums.
Two thirds of local authorities provided data for the research but just one fifth currently provide support.
According to the Centre for Social Justice the disadvantage cycle includes factors such as family disruption and poor school attendance.
But the Local Government Association says councils are doing all they can to make sure children in care have the same life chances as other children.
