Gender Disparity in Population ageing is increasingly becoming an issue for concern throughout the world because of lower mortality rate of females aged over 60 years. However, the rhythm of demographic changes including that of ageing is not spatially uniform. Within a country like India, the process of demographic transition is not operating uniformly across its varied regions. The North eastern region in India poses a very different picture compared to many other regions due to varied geographical, demographic, economic and historical reasons. This study aims at mapping the gender disparity in the Areas of Non-Tribal Dominance of North Eastern region of India. Trends have been established for a period of 40 years beginning from the year 1971 for a number of ageing indicators such as the proportion of the aged in the population, ageing index, and median age.
