5. Glossary


Gross domestic product (GDP) measures the value of goods and services produced in the UK. It estimates the size of and growth in the economy.


Production is the process of combining various materials or other inputs in order to generate a product for consumption. It includes output in the manufacturing (the largest component of production), mining and quarrying, energy supply, and water supply and waste management industries.


Services are activities that people, or businesses provide for a consumer or other businesses. The main components of the services industries are: wholesale and retail; hotels and restaurants; transport, storage and communication; business services and finance; and government and other services.

6. Measuring the data

The main data for these estimates are turnover data from approximately 1.9 million Value Added Tax (VAT) returns. Information from the Inter-Departmental Business Register (IDBR) on workplace employment allows us to apportion the VAT turnover for each business based on their employment share within a region. The quality assurance of administrative data (QAAD) report for VAT data is available.

Other volume measure data are used where appropriate, or where VAT data has insufficient coverage. A full list of other data sources is included in the methodology article.

A detailed analysis of these new data was published in the Economic Review on 21 October 2019.

As part of the quality assurance process, the Department for Environment, Food and Rural Affairs (Defra) previously notified us that they have improved their methodology for estimating regional breakdowns of the agricultural accounts. Unfortunately we were unable to process these data in time for the previous (September) release. These new estimates have now been used in the compilation of this release and the breakdown of agriculture included in the tables.

Another omission in the previous (September) release was that of the Extra-Regio region. This is economic activity that cannot be assigned to a region, such as North Sea exploration work and the activity of UK embassies abroad. In the previous release there were quality issues with the data, which have now been resolved and estimates for Extra-Regio are now presented in the tables.

7. Strengths and limitations

These data are designated as Experimental Statistics. These are statistics that are in the testing phase and not yet fully developed. We will continue to develop these statistics and seek users’ views on their uses and needs for these data.

While the data sources and methods used in both our regional and national estimates of GDP are broadly similar, there are some clear differences. For example, in the extent to which Value Added Tax (VAT) data are used.

These estimates aim to produce the best estimates at a subnational level. However, the sum of the UK regions may not equal the national total, reflecting that there are some differences in data sources and methods. We have constrained our regional GDP estimates in such a way that minimises the changes to the region by industry quarterly growth rates. While the overall impact of this constraining on the regional estimates is small, we will continue to examine the impact of this method and consider options to determine which one is best suited to these data in advance of applying to be assessed as National Statistics.

Please note that the one industry that is not fully constrained is mining and quarrying. In this industry there were challenges in chain-linking the data from the regional accounts. We will address this in the regional accounts publication in December 2019 allowing subsequent quarterly releases to be fully constrained.

Following the announcement by the UK Statistics Authority in March 2019, Construction Output Price Indices, Great Britain construction output statistics and Construction new orders were re-designated as National Statistics. It was noted, however, that the subnational and subsector breakdowns were excluded from consideration because of concerns around the path of the subnational estimates of construction output. We have worked closely with the Construction Statistics Steering Group and Consultative Committee on Construction Industry Statistics (CCCIS) on improving these estimates.

While these users have acknowledged the improvements in the modelling of these estimates, there is ongoing development work to improve these lower-level estimates as we ultimately look to regain National Statistic status in due course. Any developments in this area will in turn lead to improved accuracy in the Regional GDP estimates.
