Thank you for your enquiry
We are responsible for the provision of statistics in England and Wales. Data for Scotland and Northern Ireland are produced by National Records Scotland and NISRA. They can be contacted at foi@nrscotland.gov.uk and info@nisra.gov.uk respectively.
Unfortunately, we would be unable to provide you with the data you have requested. In order to fulfil this request, we would need to create a bespoke analysis. Under the Freedom of Information Act 2000, Public Authorities are not obligated to create information in order to respond to requests. We therefore consider this to be information not held.
If you are interested in commissioning bespoke datasets, please contact health.data@ons.gov.uk to discuss your enquiry further. Such services would be subject to legal frameworks, disclosure controls, resources and agreement of costs. Please note, there will be a charge for this work which would be subject to our charging policy.
