Overview

Summary of dataset and variables

Gross Value Added (GVA) estimates the total output of an economy. This dataset provides a breakdown of GVA for the International Territorial Level (ITL) regions, by year.

Three different measures are available for each area, namely the GVA amounts in £ million, GVA per head, and GVA per head indexed to UK = 100.

Under the European System of Accounts 1995 (ESA95), the term Gross Value Added (GVA) is used to denote estimates that were previously known as Gross Domestic Product (GDP) at basic prices. Under ESA95 the term GDP denotes GVA plus taxes (less subsidies) on products i.e. at market prices. Regional Accounts publish figures at basic prices so have adopted the term GVA rather than GDP.

Data collection or calculation

Regional GVA is calculated at current basic prices using the balanced approach.

Statistical quality

Sub-regional GVA is measured in current prices, which means that increases over time reflect inflation as well as real growth. Trends in total GVA cannot be analysed easily without deflating the data. For analysing trends in GVA, we would advise using the chained volume measures published by ONS.

Estimates of sub-regional GVA at basic prices presented here are consistent with the 2024 edition of UK National Accounts - The Blue Book.

Revisions information:

In 2025, ONS updated the International Territorial Levels (ITL) geography framework. This has led to changes to the sub-region classifications for Wales at the ITL2 and ITL3 levels.

As such, we are unable to indicate which data have been revised from the 2024 update, revision notes will be reinstated with the 2026 publication.

Rounding applied

Figures are rounded and so there may be some apparent slight discrepancies between the sum of constituent items and the totals as shown.
