based on WID data. The 300-page report cautions that since 1980, around the globe, there has been an increase in the gap between rich and poor. In Europe, the increase in inequality increased more moderately while in North America and Asia, the increase was rapid. In the Middle East, Africa, and Brazil, income inequality did not increase but remained at very high levels.
In an interview with ''Quartz'', Piketty predicted that if the "world follows the trajectory of the US" inequality would get much worse.
The 2022 World Inequality Report was published on Dec. 7th 2021. It was coordinated by economic and inequality experts Lucas Chancel, Thomas Piketty, Emmanuel Saez, and Gabriel Zucman over four years.
World Inequality Lab
The World Inequality Lab aims to promote research on global inequality dynamics. Its missions are the intension of the

, the production of analysis on global inequality dynamics, and the dissemination in the public debate.
The Lab works in close coordination with a large international network of researchers (over one hundred researchers covering nearly seventy countries) contributing to the database, in a collaborative effort to extend the existing database, which provides data on both distribution of income and wealth, "as well as the distribution of different forms of capital assets, in the analyzed countries".
By 2015, the WID provided data series on the distribution of income and wealth in 33 countries mainly from the Americas and Europe. At that time there the intention was to "include data series for an additional forty countries." The first WID in 2013, which was placed in an open source repository in September 2013, was compiled by Facundo Alvaredo,

From 2016 to 2017, through a 2015 Centers for Equitable Growth (CEG), Piketty, Saez, and Zucman studied Distributional National Accounts (DINA) for the United States. "DINA are defined as distributional statistics of pre-tax and post-tax income and wealth consistent with National Income and Product Accounts, and the Flow of Funds of the United States."
World Inequality Report, 2022

2018's highlights
The five part 300-page report discusses "the WID.world project and the measurement of economic inequality in Part I, trends in global income inequality in Part II, public versus private capital dynamics in Part III, trends in global wealth inequality in Part IV , "Tackling Economic Inequality"
Methodological "details on how estimations were constructed are available at the report's website".
[ ir2018.wid.world Dedicated website for World Inequality Report 2018/ref> According to the ''New York Times'', "Policy, it turns out, matters. More aggressive redistribution through taxes and transfers has spared Europe from the acute disparities that Americans have grown used to. Unequal access to education is helping reproduce inequality in the United States down the generations."] The ''Times'' article also noted that, "China's strategy based on low-skill manufacturing for export, and underpinned by aggressive investment in infrastructure, has proven more effective at raising living standards for the bottom half of the population than India's more inward-looking strategy, which has limited the benefits of globalization to the well-educated elite." Tetlow of the ''Financial Times'' described inequality as the "defining characteristic of the age" as The rich get richer and the poor get poorer
"The rich get richer and the poor get poorer" is an aphorism due to Percy Bysshe Shelley. In '' A Defence of Poetry'' (1821, not published until 1840) Shelley remarked that the promoters of utility had exemplified the saying, "To him that hath, ...
. The ''India Times'' article drew attention to the way in which " regulation and opening-up reforms in India since 1980s have led to substantial increase in inequality so much that top 0.1% of earners has continued to capture more growth than all those in the bottom 50% combined." The WIR reported that, "Income inequality in India has reached historically high levels. In 2014, the share of national income accruing to India's top 1% of earners was 22%, while the share of the top 10% was around 56%."
''Quartz'' cited the report, " nce 1980 the top 0.1% have captured as much income growth as the entire bottom half of world's (adult) population. And for the group of people in between the bottom 50% and top 1%—mostly the lower- and middle-income groups in North America and Europe—income growth has been either sluggish or flat." The WIR 2018 shows that, "The gap between rich and poor has increased in nearly every region in the world over the past few decades." Since "1980, income inequality has increased rapidly in North America and Asia, increased more moderately in Europe, and stabilized at very high levels in the Middle East, Africa, and Brazil."

In the interview with ''Quartz'', Piketty warned of the impediments to getting "a comprehensive picture of wealth", such as tax havens
A tax is a compulsory financial charge or some other type of levy imposed on a taxpayer (an individual or legal entity) by a governmental organization in order to fund government spending and various public expenditures (regional, local, or n ...
. Piketty observed that "there are financial and political forces that have a vested interest in keeping this information secret," noting the "paradox of today's globalized economy" where "we are supposed to be in the era of big data and transparency, and we see that we still don't have access to all the data sources we would need."
