The World Inequality Report 2026 (WIR 2026) is the third edition of a major report series, following the 2018 and 2022 versions. This report is a vast collaborative effort, drawing on the research of over 200 global scholars connected to the World Inequality Lab. It contributes to the world's largest dataset tracking the historical evolution of global inequality. The work behind these reports has been instrumental in redefining the understanding of inequality's scope and origins for policymakers, academics, and the public. A key focus is on highlighting the increasing separation of the global rich and the critical necessity for top-end tax justice. The findings from this research have directly influenced national and international policy discussions on topics such as fiscal reform, wealth taxation, and wealth redistribution in significant forums, including national parliaments and the G20.
