Introduction:Superagers are older adults with episodic memory performance comparable to that of adults 20 to 30 years younger. However, the majority of evidence originates from high-income countries, limiting the generalizability of findings to populations in low and middle-income countries (LMIC), such as Brazil. Therefore, the aim of this study was to estimate the proportion of Superagers within the Brazilian population and to investigate if residence area transition is associated with this group. 

Methods: We used data from the second wave of the Brazilian Longitudinal Study of Aging (ELSI), a nationally representative sample of adults aged 50 years or older. Participants with a history of stroke, Parkinson’s disease, Alzheimer’s disease, proxy interviews, or missing cognitive data were excluded. Superagers were defined as those aged ≥75 years with episodic memory performance comparable to adults aged 50–60 years, alongside preserved verbal fluency and temporal orientation. Lifetime residence transition was categorized by comparing childhood, before age 15, and current residence into: Rural-Rural, Rural-Urban, Urban-Rural, and Urban-Urban The association between residence transition and superaging was assessed using logistic regression.
