Income Inequality in Latin America: A Comprehensive Review
Introduction
How much income inequality is there in Latin America? Is inequality today higher or lower than it was in the 1990s, in the aftermath of the debt crisis? Has the evolution of inequality followed a particular pattern?
Debates on inequality levels and trends are rampant, and Latin America is no exception. Drawing on a comprehensive compilation of inequality measures, this report reviews the measurement of income inequality in the region over the last seven decades. The report emphasizes the importance of understanding the different estimates available and the need to analyze the phenomenon of income inequality in Latin America.
Measurement of Income Inequality
Figure 1: Gini coefficients in Latin America and the Caribbean, 1948-2021
- The report presents Gini coefficients, the most frequently used inequality measure, for 18 Latin American countries over a span of 75 years.
- The data is drawn from various sources, including harmonized estimates from household surveys, secondary source estimates, and individual studies.
- The range of inequality estimates is considerable, with variations depending on the country and time period.
How Unequal is Latin America?
The report provides average Gini coefficients for the 2010s based on harmonized databases from comparable surveys. The countries with the highest levels of income inequality are Brazil, Colombia, and Panama, while Uruguay has the lowest level of income inequality.
Evaluation of Inequality Measures
When tax data is used to correct for top incomes misreporting and attempts are made to scale up to national accounts estimates of national income, Gini coefficients are found to be higher on average. However, these methods involve assumptions and decisions that are not easily validated, leading to considerable uncertainty about the exact levels of income inequality in the region.
Evolution of Inequality Measures
The report finds that the evolution of inequality in Latin America follows a broad inverted-U curve, with inequality rising before the 1990s and falling during the early 21st century. However, there are variations in timing and magnitude among different countries.
Conclusion
The report acknowledges the progress made in data collection to measure inequality in Latin America. It also highlights the need for further improvements in data sources and the existence of a relatively robust pattern of inequality dynamics. Researchers are encouraged to explore the drivers and mechanisms behind income inequality in the region.
