Each year, the UN releases its Human Development Report, which looks at the overall progress of nations as measured by one statistic called the Human Development Index. This single statistic is made up of three primary components — life expectancy, education and income. This visualization shows you each country’s HDI rank along the x-axis while the y-axis shows the impact on each country’s HDI when the inequality within that country is factored in – what’s called the Inequality-Adjusted HDI. You can filter to look at countries by region or by the four levels of HDI. And you can see this inequality impact either as a percentage change in HDI or by the impact that change has on a country’s ranking.
