Much of the information presented in Scotland Office publications draws on material published elsewhere, including both PESA, published by HM Treasury, and Government Expenditure and Revenue in Scotland, published by the Scottish Government, both of which are classified as National Statistics. Some material published in the Scotland Office annual report is derived from data collected for administrative purposes. In keeping with any information in the public domain, no protocols exist for the use of information published by other Departments and classified as National Statistics.
