Exploring global income inequality.

About

We build an interactive visualisation demonstrating the changing distribution of global market income since 1980. Our PPP-adjusted data on market income comes from the World Inequality Database (WID).

You can also download the data here in xlsx or csv formats.

Below you can see the global market income distribution in 2020. Market income refers to the annual earnings of individuals before taking into account government transfers such as benefits and taxes. Taller blocks correspond to higher market income. Countries with larger populations are assigned wider blocks. Colours correspond to how rich the country was in 1980, with poorer countries shaded red and richer countries shaded green. Countries are ordered according to their national income per capita in each year, while holding colours fixed from the 1980 ordering. Therefore, with these figures we can see income inequality within and across countries over time as well as changes in national per capita income.

These visualisations were created for The CORE Project. CORE is an open-access, interactive ebook-based course for anyone interested in learning about the economy and economics.

You can also explore similar interactive visualisations of global wealth inequality and global carbon footprint inequality in our companion websites: CORE Skyscraper 2: Exploring global wealth inequality and CORE Skyscraper 3: Exploring global carbon footprint inequality.
