Understanding the role of place of birth is essential to understanding inequality of opportunities and social mobility, both of which directly affect overall inequality. This paper uses machine learning techniques and data from Colombia, one of the most unequal countries in Latin America and the Caribbean, to estimate inequality of opportunity and intergenerational education mobility indexes. The analysis incorporate place of birth and a more granular geographic lens to capture the extent of regional disparities. The findings show that 49 percent of the Gini income inequality is explained by circumstances at birth, and place of birth accounts for up to half of these inequalities. Intergenerational mobility measures at the department (province) level also reveal striking disparities in opportunities across the country. These findings underscore the critical role that place of birth plays in perpetuating inequality, providing important insights for policies aimed at promoting social mobility and reducing territorial disparities.en-USCC BY 3.0 IGOINTERGENERATIONAL MOBILITYEDUCATIONINEQUALITY OF OPPORTUNITIESLATIN AMERICACOLOMBIAWorking PaperWorld Bankhttps://doi.org/10.1596/1813-9450-11126
