The United Nations Population Fund (UNFPA) predicted, the elderly population will double, and one in every fifth person will 60 plus individuals by 2050 (24). Thus, it is essential to secure the economic and health stability of older individuals to achieve sustainable aging. It is a fact that drastic falls in fertility and increase life expectancy are booming in the elderly population; however, it is more worrying that nearly three-fourths of them are economically inactive and fully or partially depending on their family member (25–27). Literature suggests that economic stability is essential for good physical and mental health (28) for older adults, ultimately leading to sustainable aging through securing the health dimension. Using BKPAI 2011-12 data, this current study aims to explore the role of remittance in securing physical (self-rated health) and mental health (depression) among left-behind elderly in India.
In recent years, there has been a significant increase in scholarly interest regarding migration and its association with the health of left-behind parents. Traditionally, in Indian society, joint family, kinship, and community are significant sources of supporting and caring for the elderly (29). However, in the last few decades, Indian society witnessed a change in family structure from a joint to a nuclear family system due to adult-child migration and a change in the value system and thus has severe repercussions on the elderly care and support system (30). The present study found that two-fifths (43%) of the elderly sample had a male migrant child living outside the district. Following earlier research (16, 31) the present study also found that the absence of a male child has a negative impact on self-rated health and major depression among the elderly.
Further, several socioeconomic factors, age, sex, wealth, and economic dependency, intensify the level of poor self-rated health and depression. Higher economic dependency on a population has the potential to strain a country's resources due to expenditure on food, health, and social security (32). Therefore, there is a high dependency ratio due to the rapid growth of the elderly population in India (28). For instance Kumar & Kumar, 2019 found that around 70 percent of Indian elderly economically depend on other family members. Thus, the responsibility of caring for the elderly falls on adult earning members. Consistent with (28) study, our result also shows that around a fourth of the study population economically depends on other family members, leading to poor physical and mental health (33).
Moreover, our study also tries to find the impact of financial support or compensation effect of remittance on self-rated health and depression among left-behind elderly. Consistent with other studies (Tachibana et al., 2019) our study also found that elderly parents who receiving remittance has a significant impact on improve self-rated health. In other words, remittance sent by migrant children contributes to their left-behind family members' well-being in India. The possible explanation is that their children's remittances enable spending on food or medical expenditures, and extra money enables them to take time off from farming to leisure activities and relaxation (35). However, long-term separation from children has severe mental health costs for the left behind elderly members, as it increases the probability of suffering from loneliness and depression (36–39). In this context, the communication between left-behind parents and their migrant children plays a crucial role in maintaining the psychological health of older parents (40). This connection helps bridge the physical distance and emotional separation, offering emotional support and reassurance to the elderly family members, thereby contributing to their overall well-being (41). Finally, our study findings conclude that although remittance significantly compensates 50 percent of the impact of migration on self-rated health, the overall cost of adult child migration on physical and mental health is much greater than the effect of remittance.
