To ask the Chancellor of the Exchequer what revisions to the definition of public sector productivity there have been since 1997; and how many times this definition has changed since 1997. (166746)

Productivity is the relationship between inputs and outputs and the measurement of public sector output and therefore of public sector productivity is technically complex. The Atkinson review was set up by the National Statistician to independently review the future development of measures of government output, productivity and associated price indices. Following the Review's report in 2005 the National Statistician set up within the Office of National Statistics (ONS) the UK centre for the Measurement of Government Activity (UKCeMGA) to take forward the review's findings. This work is continuing and regular progress reports are published by UKCeMGA on their website.
