Data for Scotland and the UK
GDP figures for Scotland are produced by the Office of the Chief Economic Adviser (OCEA) in the Scottish Government. Scottish GDP is a quarterly National Statistic published on pre-announced dates in January, April, July and October. Further details on Scottish GDP statistics, including methodology notes, are available at: http://www.scotland.gov.uk/gdp
Figures used for comparing GDP performance between Scotland and the UK refer to GDP at basic prices, also known as Gross Value Added (GVA). UK figures are taken from the Office for National Statistics' (ONS) Quarterly National Accounts publication, and the headline CGCE series is used (which includes output from the North Sea oil and gas sector).
Data for Small EU Countries
GDP growth data for the Small EU countries is collected from the Organisation for Economic Cooperation and Development (OECD). The data series used provides GDP volume estimates in constant prices, and fixed Purchasing Power Parities (PPP).
This data is available in the OECD statistics web site and can be found through the following link, http://stats.oecd.org/WBOS/index.aspx.
Rolling Annual (4Q on 4Q) Growth Measure
Quarterly Scottish GDP estimates tend to fluctuate more than UK results because in a smaller economy each sampled unit is more likely to have a noticeable effect on the total. To reduce the quarterly volatility in growth rates and give a true indication of recent trends, a rolling annual measure - which compares the most recent four quarters to the previous four quarters - is used for the purposes of this calculation.
In order to ensure consistency in the measurement of performance against the GDP growth targets annual GDP growth rates for the UK and the Small EU countries are also calculated using the 4 quarters on 4 quarters approach.
Users should be aware that the Scottish Government Quarterly GDP publication and the ONS statistics for the UK report annual growth as being the latest quarter compared to the same quarter in the previous year. Total GDP figures for the UK are also usually given at market prices and not basic prices. The figures used in the Scottish Government National Performance Framework can therefore differ from results reported in other publications.
