Please see below for a summary of important quality information that you need to know before using these data. The Regional Gross Value Added Income Approach (GVA(I)) 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(I) data:
Regional GVA is the value generated by any unit engaged in the production of goods and services. Regional GVA(I) is measured using the income approach which involves adding up the income generated by individuals or corporations in the production of goods and services: it is calculated gross of deductions for consumption of fixed capital, which is the amount of fixed assets used up in the production process in any period.
The regional GVA(I) estimates cover the UK as a whole and are allocated to 12 NUTS1 regions, 40 NUTS2 sub-regions and 173 NUTS3 local areas, using a top down approach.
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.
Regional GVA(I) estimates are presented in current basic prices, excluding taxes (less subsidies) on products.
The production of regional GVA(I) is a legal requirement of the European Union (EU). 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(I) estimates are delivered to the statistical body of the EU, Eurostat, along with regional GVA collected from all member states and is used in the allocation of Objective 1 structural funding. The structural funds account for approximately one-third of the EU budget.
GVA(I) 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(I) estimates are compiled at three 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
- NUTS3: 173 local areas - principally individual counties and unitary authorities
Estimates are published on a workplace basis using the Standard Industrial Classification 2007 (SIC 2007) in keeping with EU regulations. At NUTS1 and NUTS2 levels, data are provided for 20 industries plus 13 manufacturing sub-sections. At the NUTS3 level, GVA(I) data by 10 industries are available.
