Managing for results is an important principle and is an objective for projecting into the future. This calls for population projection to provide what changes might occur given the assumptions inherent in the projection method and the data. There are a number of techniques for population projection. The Bureau decided to use cohort component method. The method uses the components of demographic change to project the population into the future. It projects the population by age and sex.
The projection builds on the 2008-2015. It uses the projected figures for 2015 as the base population. The parameters used are those derived from SSHHS 2010 data. These are the age specific fertility rates (ASFRs) and the age specific mortality rates (ASMRs). The ASMRs are the values in the relevant life tables.
