Capital in the 21st Century bases its analysis of wealth inequality on tax data from 29 countries over one
hundred years. This data is openly available as
The World Top Incomes Database (WTID). To create a sharable,
interactive visualization of global inequality, Carnegie Mellon's
CREATE Lab is releasing this explorable viewer
for WTID. See how the income of the wealthiest classes have evolved, and how much greater wealth the top 1% have
compared to the rest of society in each country. A
quick tour of the tool is available.
