The Regional Gross Value Added Production Approach (GVA(P)) quality and methodology information (QMI) PDF attached below contains further information on:
- the strengths and limitations of the data
- the quality of the output, including its accuracy and how it compares with other related statistics
- uses and users
- how the output is created
Important points about Regional GVA data:
Regional GVA is the value generated by any unit engaged in the production of goods and services
Regional GVA(P) estimates are compiled using the production approach and produced using both current and constant prices
Estimates are produced annually in December in the form of a statistical bulletin. This release is currently classed as an experimental statistics publication. These are defined in the Code of Practice for Official Statistics as new official statistics undergoing evaluation. They are published in order to involve users and stakeholders in their development and as a means to build in quality at an early stage
National totals are consistent with the UK National Accounts (Blue Book) and are allocated to regions using the most appropriate available regional indicators.
A regional indicator is a dataset which provides data for calculating regional proportions which are used to allocate national totals; they are derived from administrative sources and surveys.
The regional GVA(P) estimates cover the UK as a whole and are allocated to 12 NUTS1 regions and 40 NUTS2 sub-regions.
The production of regional GVA(P) is a legal requirement of the European Union. Estimates are compiled in compliance with the European System of Accounts 2010 (ESA10) and are consistent with the standards set out in the United Nations System of National Accounts 2008 (SNA08).
GVA(P) estimates cover the whole UK and are broken into smaller areas as defined by the nomenclature of units for territorial statistics (NUTS). The NUTS system provides a breakdown of the European Union’s territory and is used to produce regional statistics which are comparable across the EU.
GVA(P) estimates are compiled at two levels of NUTS geography:
- NUTS1: 12 regions - Wales, Scotland, Northern Ireland and nine English regions
- NUTS2: 40 sub-regions - mainly groups of counties and unitary authorities
Estimates are published on a workplace basis using the Standard Industrial Classification 2007 (SIC 2007) in keeping with EU regulations. Data are provided for 20 industries plus 13 manufacturing sub-sections.
