Population dynamics in the south-west of Bangladesh

Abstract

Demographic trends and projections have important implications for the use of ecosystem services and sustainability in the delta. The study area accounts for ten per cent of the national population and recently appears to have low rates of population growth. Analysis of components of population change (fertility, mortality and migration) indicates that over the next few decades the population structure will undergo considerable change. These demographic trends are explained by declining fertility, greater life expectancy and high rates of out-migration. More specifically, the proportion of 65 and over is likely to increase from 6 per cent in 2011 to 15–16 per cent by 2051. Conversely, the proportion of children and youth (ages 0–14) would decline from 34 per cent to 15–16 per cent depending on the scenario considered.
