It has emerged that the number of 10- to 17-year-olds subject to proceedings rose by 95 per cent between 2011/12 and 2019/20, from 3,081 to 6,013 children.
Meanwhile, the number of 16-year-olds involve in proceedings has almost quadrupled, rising by 285 per cent over that time, according to the research.
There has also been a sharp rise in the number of 15-year-olds involved in care proceedings, by 150 per cent.
The rise among 10- to 17-year-olds is faster than any other age group, says the research by Nuffield Family Justice Observatory.
