LORAA, Eduardo. Anatomy of Income Concentration in Colombia. Desarro. soc. [online]. 2025, n.99, pp.11-32.  Epub Jan 15, 2025. ISSN 0120-3584.  https://doi.org/10.13043/dys.99.1.

Certain structural features of income inequality in Colombia remain underexplored. Drawing on microdata from the 2022 DANE Large Integrated Household Survey (GEIH), this study examines the inequality across various income categories, provides decompositions of household per capita income inequality by income sources, and analyzes labor income inequality both within and between groups to assess their contributions to overall inequality. The findings reveal that only half of the observed income concentration stems from disparities in labor income. Furthermore, the concentration of labor income is driven primarily by inequalities within groups rather than differences between them. Among the groups analyzed, individuals with higher education and self-employed workers are the largest contributors to inequality. These insights suggest that future studies should focus on these specific groups to identify the most effective policy interventions for reducing inequality.
