As Europe’s population ages, understanding the mental health of older adults, particularly migrants, is more urgent than ever. This study explores suicidal ideation among people aged 50+ in the Visegrad, Baltic, and Nordic countries, using SHARE Wave 9 data (N = 20,996, including 1,356 migrants). While suicidal thoughts were more commonly reported by migrants (6.9%) than non-migrants (4.8%), this difference vanished after adjusting for factors like age, education, loneliness, and depressive symptoms. Although migration status alone was not a significant predictor, separate analysis revealed that migrants were uniquely vulnerable to the effects of rural living. Using both single- and multilevel logistic regression, we found that individual-level factors, rather than country or region, explained most of the variance in suicidal ideation. Still, the socio-geographical context matters: rural-dwelling migrants appear at particular risk. By focusing on a rarely studied intersection of age, migration, and mental health, this study underscores the need for targeted support strategies. As aging and migration reshape Europe, emotional well-being must be at the heart of suicide prevention efforts.
