The final demand vectors form one part of a complex methodology for deriving the estimates of UK employment dependent on MOD expenditure and defence exports, and associated breakdowns on MOD expenditure in UK industry and commerce. The latest aggregate information on the non equipment and equipment vectors is published by the Defence Analytical Services Agency (DASA) in Table 1.9a of "UK Defence Statistics 2007", a copy of which is available in the Library of the House.
In isolation the raw underlying data used to construct these vectors will not reconcile to these final published estimates as a series of internal adjustments are made to the vectors prior to publication. Moreover, the vectors will also not reconcile to the published MOD resource accounts since they are constructed using cash rather than resource data. To correct these raw figures to make them consistent with published accounts would involve disproportionate cost.
A full account of the methodology, associated caveats and descriptions of the data sources used to construct these vectors can be found in the DASA "Defence Statistics Bulletins Nos. 5 and 5A", both of which are available in the Library of the House.
