Produced by a team of world-leading economists, this is the benchmark account of recent and historical trends in inequality. World Inequality Report 2022 is the most authoritative and comprehensive account available of global trends in inequality. Researched, compiled, and written by a team of world-leading economists, the report builds on the pioneering edition of 2018 to provide policy makers and scholars everywhere up-to-date information about an ever broader range of countries and about forms of inequality that researchers have previously ignored or found hard to trace. Over the past decade, inequality has taken center stage in public debate as the wealthiest people in most parts of the world have seen their share of the economy soar relative to that of others. The resulting political and social pressures have posed harsh new challenges for governments and created a pressing demand for reliable data. The World Inequality Lab, housed at the Paris School of Economics and the University of California, Berkeley, has answered this call by coordinating research into the latest trends in the accumulation and distribution of income and wealth on every continent. This new report not only extends the lab’s international reach but provides crucial new information about the history of inequality, gender inequality, environmental inequalities, and trends in international tax reform and redistribution. World Inequality Report 2022 will be a key document for anyone concerned about one of the most imperative and contentious subjects in contemporary politics and economics.
