Explanatory note for experimental current price GVA for 2005 and 2006

In order to free up resources necessary to allow delivery of the modernised National Accounts systems and methods, the annual updating of the GDP accounts through the Input-Output Supply and Use framework did not take place in Blue Book 2007. As a result table 2.3 Gross Value Added (GVA) by industry at current prices will not be available. Data for the years 2005 and 2006 are being published as experimental statistics.

It should be noted that the experimental 2005 and 2006 current price GVA data include estimates for private investment in own account computer software. However, in the absence of full Supply and Use balancing this year estimates for 2005 and 2006 have used a simplified approach, which does not involve detailed allocation of the production of the own-account software across industries. Current price GVA up to and including 2004, as published in Blue Book 2006, does not reflect any estimates made for the production of own-account software.

The estimates of current price GVA data for 2004 and earlier were estimated by balancing Input-Output Supply and Use framework, which drew on survey data from ONS's Annual business Inquiry (ABI). Estimates of current price GVA data for 2005 and 2006 is based on short-term indicators and is less firm. Revisions to the early estimates of GVA over recent years indicate that this approach is not ideal.
