We measure product market concentration and business dynamism in the UK from 1997 to 2020. We document this with administrative data on the population of UK firms from the Business Structure Database (BSD). Our results show that concentration in the UK is increasing among narrow industries on average, but for a broad market definition concentration and business dynamism are stable. Lastly, we document a negative relationship between concentration and productivity.
