The purpose of this study is to identify and analyze distinct profiles in a displaced population from areas at high risk of disasters in Belo Horizonte, Brazil, according to socioeconomic and demographic characteristics. Specific groups are more vulnerable than others in urban areas prone to disaster risk, particularly those deprived of public services, engaged in low-income activities, inhabiting informal settlements, and exposed to external events such as climate hazards. In Belo Horizonte, the sixth most populous city in Brazil, nearly 390,000 people live in areas prone to disasters such as floods, landslides, and other events related to rainfall patterns. In this study, we propose a methodology based on cluster analysis and PCA (Principal Component Analysis) to identify subgroups with similar characteristics among the resettled population between 2010-2020 from risk areas in Belo Horizonte. We discuss how this methodology can help to better design populational policies to target vulnerable groups exposed to the effects of sudden events and further effects of climate change.
