Thank you for your recent request.

ONS is the executive arm of the UK Statistics Authority, a non-ministerial department responsible directly to Parliament.

We hold records of the number of deaths by suicide for England and Wales, the number of deaths by suicide are provided by National Records of Scotland and Northern Ireland Statistics and Research Agency to produce statistics for the UK, which can be found here:

The information we hold on deaths is limited to what is recorded on the death certificate by a doctor or information about the cause and circumstances of the death provided by a coroner. We can provide the number of suicides per year by key variables such as age, sex and geographical area. Detailed information on motives of suicide are not generally available.
