This paper joins the debate on the size of the middle class in Latin America, analysing its structure and characteristics. The paper investigates inter-class mobility potential and its evolution over time in the case of selected countries. As a result of the estimations, we find that Latin American countries have smaller middle classes than OECD countries. Moreover, this comparison shows that, while middle-class upward mobility potential is not very different, middle class resilience is higher in OECD countries. This suggests that particular attention should be paid to mitigating the impact of economic reversal on middle-class families, as they are more vulnerable to falling into poverty. This analysis provides a tool to identify the features of the middle class that need to be promoted by policy makers to foster middle-class resilience and enhance its stabilising role in society.
