Title: Studying poverty at scale: research with the CIDACS 100 Million Brazilian Cohort

Abstract: The Center for Data and Knowledge Integration for Health (CIDACS/Fiocruz) maintains the 100 Million Brazilian Cohort, one of the largest population cohorts in the world. Built from the Unified Registry for Social Programs (CadÚnico), it includes more than 100 million people who applied for social benefits in Brazil, linked to national records on mortality, births, disease notifications and social programmes. Its scale and coverage make it possible to study the living conditions, health and life trajectories of the low-income population with a level of detail that conventional surveys cannot reach, including small and historically invisible groups.

This presentation introduces CIDACS and the cohort and discusses four examples of what these data allow us to understand. First, a synthesis of the evidence produced on the Bolsa Família Programme and its effects on health and mortality. Second, the Quilombola Bulletin, which describes the living conditions of quilombola communities, traditional Afro-Brazilian populations. Third, preliminary results of an evaluation of the Continuous Cash Benefit (BPC) for older adults and its effects on mortality. Finally, an ongoing study identifying same-sex couples in CadÚnico and describing their characteristics.
