This is an ad-hoc release of management information and does not constitute an Official Statistics or National Statistics release.
The Code of Practice for Statistics was published by the UK Statistics Authority in February 2018 to set standards for organisations in producing and publishing official statistics and ensure that statistics serve the public good. Whilst the data are not designated as official statistics, the principles of transparency of high-quality analytical outputs to inform decision making and the public underpin this data release: a statement of compliance is available at the ‘Voluntary compliance’ tab of the spreadsheet of tables.
