“…There is a dearth of studies that produce research on old age mortality at the regional level in India. Furthermore, the majority of the previous studies have paid much attention to infant (Dyson & Moore, 1983; Gupta et al, 2016; Jain, 1985), child (Bora, 2020; Liu et al, 2019) and adult mortality (Panda & Mishra, 2021; Saikia et al, 2011; Saikia & Moradhvaj, 2021) than old age mortality; as a result, more is known about regional variations in infant, child and adult mortality than the latter age in India. Therefore, our study attempted to fill this gap.…”
