Welcome to the Children and Young People's Mental Health and Wellbeing Profiling Tool. It has been developed to support an intelligence driven approach to understanding and meeting need. It collates and analyses a wide range of publically available data on risk, prevalence and detail (including cost data) on those services that support children with, or vulnerable to, mental illness. It provides commissioners, service providers, clinicians, services users and their families with the means to benchmark their area against similar populations and gain intelligence about what works.
