All children who had been looked after for at least 13 weeks which began after they reached the age of 14 and ended after they reached the age of 16.
Numbers have been rounded to the nearest 10.
Figures exclude children who were looked after under an agreed series of short term placements, those who have died since leaving care, and those who have returned home to parents or someone with parental responsibility for a continuous period of at least 6 months.
The care leavers cohort changed for 2014 along with the addition of collecting data for 20 and 21 year olds. Prior to 2014, data was collected for 19 year olds only who were looked after aged 16. Due to the change of cohort, data for 2014 should be treated with caution.
