Figures reported by the Adam Smith Institute (ASI), a free-market think tank, indicate the number of people with millionaire wealth in the UK falls to the lowest level seen in 20 years. The ASI estimates there are 442,000 millionaires in Britain, which represents a 7% decline compared with 2024. The report frames this drop as a continuation of a downward trend in the number of millionaires over recent years, citing the latest ASI data as evidence that the count has not been this low for two decades. The figures cover the number of individuals classified as millionaires under ASI’s methodology, but the provided reports do not detail specific drivers behind the decline, such as changes in asset values, household wealth, or broader economic conditions. The coverage reflects the ASI’s interpretation of the data and highlights the year-on-year reduction in millionaire numbers, using the 20-year comparison to characterize the decline as the largest relative low point within that timeframe.
