Formal volunteering in later life is beneficial for both physical and psychological well-being. However, research points to potential selection bias because older adults with key advantages, such as wealth, are more likely to volunteer and reap its benefits. Accordingly, this study addresses this selection bias by considering the characteristics of volunteers and nonvolunteers using the inverse probability of treatment weighting. It also examines whether volunteering has differential impacts between the highest and lowest wealth quintiles using inverse probability of treatment weighting.
