A Study of Comparing Total Population of Bangladesh with Age- Structured Linear Sharpe-Lotka Model and Malthusian Model.

Abstract

We consider an age-structured linear continuous population model named Sharpe-Lotka model, incorporating an factor contributes to limiting effect which may be occur due to lack of resources. This factor depends on the whole population rather than on any specific age group. In our paper, we investigate the total population size of Malthusian model and Sharpe-Lotka model for some specific age group & compare our investigated solutions with the total population of Bangladesh by using numerical method “Newton’s backward interpolation formula”.
