We have overhauled our historical forecast database so that it now includes successive forecasts and recent outturn data for many more variables – including all the main lines of tax and public spending, plus the major fiscal aggregates (such as public sector borrowing and debt) – from our forecasts since 2010. The database also includes most of the economic and fiscal forecasts published by the Treasury prior to 2010 and in some cases back as far as 1970.
