Lower and upper bounds of life expectancies and total expected longevity of a developing country

Regardless of being most used demographic indicator of longevity, life expectancy has few limitations too; and it arise mainly due to irregular mortality patterns in particular age group. This paper aims to analyze the trend of remaining life expectancies in different age groups and examines the highest observed life expectancies along with lower and upper bounds of life expectancies for Bangladesh; a country where early aged mortality is present remarkably. To estimate the lower and upper bounds of life expectancies in particular age; corresponding survival fractions have been taken into account, which gave more flexible concepts about longevity measures. Obtained results indicate decline in the gap between early aged life expectancies for both sexes in Bangladesh; which suggests that the full population, rather than just the more selected survivors, may anticipate a longer life that was previously only the domain of those who survived past the early years.
