Economic Inequality
How are incomes and wealth distributed between people? Both within countries and across the world as a whole?
On this page, you can find all our data, visualizations, and writing relating to economic inequality.
This evidence shows us that inequality in many countries is very high and, in many cases, has been on the rise. Global economic inequality is vast and compounded by overlapping inequalities in health, education, and many other dimensions.
But economic inequality is not rising everywhere. Within many countries, it has fallen or remained stable. And global inequality – after two centuries of increase – is now falling too.
The large differences we see across countries and over time are crucial. They show us that high and rising inequality is not inevitable, and that the extent of inequality today is something that we can change.

About this data
This data explorer provides a range of inequality indicators measured according to two different definitions of income obtained from different sources.
- Data from the World Inequality Database relates to inequality before taxes and benefits.
- Data from the World Bank relates to either income after taxes and benefits or consumption, depending on the country and year.
Further information about the definitions and methods behind this data can be found in the article below, where you can also explore and compare a much broader range of indicators from different sources:

Research & Writing
How has income inequality within countries evolved over the past century?
While the steep rise of inequality in the United States is well-known, long-run data on the incomes of the richest shows countries have followed a variety of trajectories.
Income inequality before and after taxes: How much do countries redistribute income?
The redistribution of income achieved by governments through taxes and benefits varies hugely.
