Release of the World Inequality Report 2018

The World Inequality Report 2018, coordinated by Facundo Alvaredo, Lucas Chancel, Thomas Piketty, Emmanuel Saez and Gabriel Zucman was released and presented today at the Paris School of Economics during the first Conference.

The report draws on recent data to provide the first assessment of globalization in terms of inequality, over the past 40 years. It shows that the global top 1% of the world’s adult population captured twice as much growth as the global bottom 50% since 1980.

The report also provides novel insights on income inequality dynamics in emerging countries, discusses the evolution of public and private wealth as well as the evolution of wealth inequality within countries and at the global level. The report presents projections of global income and wealth inequality dynamics up to 2050. The report is available online on, along with all its associated methodological document and raw data sets.
