Overview

Summary of dataset and variables

What is the supply table

This dataset contains a summarised supply table showing the value of products supplied to the Welsh economy.

It sets out how much of each product is produced domestically, how much is imported, and the adjustments required to express total supply in purchasers’ prices.

What is the table used for

The supply table is used alongside the use table to describe the relationship between supply and use in the economy, where total supply and total use of each identified product are equal.

Together, the supply and use tables form the foundation for constructing input‑output tables and for wider economic analysis.

How is the table structured

Supply of products is shown in the rows of the table.

The columns summarise the geographic sources and price adjustments for each product. The sum of these columns equal supply at purchasers’ prices.

All figures are expressed on a calendar year basis, and in millions of pounds.

Data collection or calculation

What data sources are used

The Welsh Government supply and use tables are compiled using a wide range of surveys, administrative datasets and other sources.

Further detail on data sources and methods is available in the accompanying methodology report.

How these tables compare with earlier releases

This dataset should not be compared with the 2019 release, as the methods, data sources and presentation have been substantially revised.

Statistical quality

What you need to know about data quality

The supply, use and input-output tables are designated as Official Statistics in Development (Office for Statistics Regulation).

What are the key quality limitations

  • Some parts of the tables use UK-level patterns where Wales-specific data are not currently available, including production functions for non-manufacturing industries.
  • Some estimates are more uncertain than others, particularly imports, which rely on simplifying assumptions about supply chains.
  • Some business surveys do not cover parts of the Welsh economy, so we use apportionment methods and additional data sources where needed.

As a result, the tables are best used for analysing the economy and sectors as a whole rather than individual transactions.

Rounding applied

All values are rounded to 4 decimal places. As a result, totals and subtotals may not sum exactly.

Users requiring greater precision are advised to download the data tables in OpenDocument Spreadsheet (ODS) format from the Welsh Government website.
