The UK government has released official statistics examining industry concentration from 2007 to 2025, giving a long-term view of how concentrated different parts of the economy have become over time. The publication focuses on industry-level concentration measures, which are commonly used to assess how much market activity is controlled by a smaller number of firms.
By covering the period from 2007 through 2025, the figures provide a broad timeline for tracking structural change across UK industries. That span includes years marked by major economic shifts, making the dataset useful for understanding whether markets have become more concentrated, stayed broadly stable, or changed in different ways across sectors.
Industry concentration data is closely watched because it can help inform debate around competition, market power and business dynamics. Policymakers, researchers and companies often use these measures to study how industries evolve and whether competitive conditions are changing over time.
The release adds to the evidence base on the structure of the UK economy by bringing together concentration measures across industries in one official statistical update. It offers a reference point for anyone monitoring long-run trends in market concentration and the changing shape of UK business activity.
