Information is not collected by the Department on the number of children and adults diagnosed with a mental health disorder.

The Office for National Statistics 2004 survey ‘Mental health of children and young people in Great Britain’ looked at the prevalence of mental health disorders. It found that 10 per cent. of young people aged five to 16 years had a clinically diagnosed mental disorder. This was further broken down to 8 per cent. of five to 10-year-olds and 12 per cent. of 11 to 16-year-olds. A copy of this publication is available in the Library.
