Extrapolation of Life Expectation at Birth up to Year 2051 through Distribution Fitting of Age Specific Death Rates and using Life Table for the States in North East India

The data on age specific death rates(ASDR) from Census of India at the vital statistics section, is being utilised to compute the life expectation at birth(e⁰₀) for the year 1991, 2001 and 2011 by the usual methods of life table for all the eight North eastern states of the country, where few articulated materials are available till date. The present work also attempts to compute e⁰₀ up to the year 2051, through life table by projection the input data ASDR fitted with exponential distribution.

The findings reveals that in Sikkim, e⁰₀ is not increasing for males and gender disparity exist of this indicator with females from 2011 to 2051. In Meghalaya, e⁰₀ values is well below the country levels from 1991 to 2051. In Mizoram, the indicator is decreasing in case of females from 2021 through 2051. Trends of e⁰₀ in other states in the region are encouraging.
