This study investigated how early, “on-time,” and late home leavers differed in their relations to parents in later life. A life course perspective suggested different pathways by which the time spent in the parental home may set the stage for intergenerational solidarity in aging families. Using fixed-effects models with data from the Survey of Health, Ageing and Retirement in Europe (N = 14,739 parent – child dyads), the author assessed the effects of previous coresidence on intergenerational proximity, contact frequency, and support exchange more than 5 years after children had left home. The results indicated that, compared with siblings who moved out “on time,” late home leavers lived closer to their aging parents, maintained more frequent contact, and were more likely to be providers as well as receivers of intergenerational support. Overall, this evidence paints a positive picture of extended coresidence, revealing its potential to promote intergenerational solidarity across the life course.
