Modeling population growth of Sri Lankan cities

Abstract

This paper reports the findings of a study to test the population growth models to predict the population growth of two Sri Lankan cities; Batticaloa and Ampara. We study the population growth models; Malthusian’s exponential growth model and logistic growth model and develop a new model to predict the population growth for Batticaloa and Ampara using the logistic growth model. We use the population data from the census population and the calculated populations by the Department of Census and Statistics of Sri Lanka.
