Population projections area basic requirements in planning and are primarily used as bases for estimating future needs for basic services (e.g. education and health services, determining level of demand for facilities and utilities, economic-related needs and corresponding spatial requirements, among others.

The geometric rate or the mathematical method was used in determining growth rate from the period 2000 TO 2010. The derived annual growth rate was used in estimating population projections for the planning year 2016 and the planning period from 2017-2026. Derived total annual population growth rate is 1.53%. The following tables show population projections.
