Abstract:
Population is a dynamic feature in both global and regional contexts. The Department of
Census and Statistics estimated population growth in Sri Lanka for 2014 as 0.86% and fertility
rate in 2012 is 2.35 births per woman, along with more than 20 million people in the
country. Even from these facts it is clear that the population is increasing and it will continue
to be. Understanding the spatial distribution of people will provide a solid foundation when
planning for the necessities of this population. Not only the distribution of population density,
but also the gravity of population can be used as an analytical tools when identifying the spatial
patterns
