Map Of Countries By Gini Coefficient 1990 To 2020

Key Takeaways

  • The Gini Coefficient measures income inequality within a country.
  • This map provides an overview of Gini Coefficient values from 1990 to 2020.
  • Understanding income inequality is essential for policymakers and researchers.


The Gini Coefficient, also known as the Gini index or Gini ratio, is a statistical measure of income inequality within a country. It was developed by Italian statistician Corrado Gini in 1912. The coefficient ranges from 0 to 1, where 0 represents perfect equality and 1 represents extreme inequality.

Since the 1990s, there has been an increasing interest in measuring and analyzing income inequality around the world. The Gini Coefficient has become a widely used tool to study the distribution of income within and between countries. By comparing Gini Coefficients over time, researchers can identify trends and changes in income inequality.

1. What does the Gini Coefficient measure?

The Gini Coefficient measures income inequality within a country. It provides an indication of how wealth and income are distributed among the population.

2. How is the Gini Coefficient interpreted?

A Gini Coefficient of 0 represents perfect equality, where everyone has an equal share of income. A coefficient of 1 represents extreme inequality, where a single person or group holds all the income.

3. Is income inequality increasing globally?

Yes, income inequality has generally been increasing globally since 1990. However, the degree of inequality varies between countries and regions.

4. Which countries have the highest Gini Coefficients?

Countries like Brazil, Colombia, and South Africa consistently rank among the countries with the highest Gini Coefficient values, indicating higher income inequality.

5. Which countries have the lowest Gini Coefficients?

Nordic countries such as Denmark, Sweden, and Norway consistently have some of the lowest Gini Coefficient values, indicating lower levels of income inequality.

6. Are there any countries that have experienced a decrease in income inequality since 1990?

While overall the trend has been towards increasing income inequality, some countries have managed to decrease their Gini Coefficient values. One example is Lithuania, which experienced a decrease in income inequality between 1990 and 2000.
