The number and ages of deaf children in England is not collected centrally. Instead, data are collected on the number of children who are registered as deaf or hard of hearing. Inclusion on the register is voluntary and therefore, does not provide a complete picture of the number of children in England who are deaf or hard of hearing.
Registers of Deaf and Hard of Hearing People (SSDA910) are collected by the NHS Information Centre every three years, and was last collected in 2006-07. This collects the number of people registered as deaf or hard of hearing with councils with social services responsibilities (CSSR).
