Demography is defined as the study of the size, structure, dispersement and development of human populations in order to establish reliable statistics on such factors as birth and death rates, marriages and divorces, life expectancy, and migration (Earle et al., 2007). It has been recognised that the understanding of the size, structure, past and future development of a population is fundamental to an understanding of its health. Therefore this understanding is regarded as a prerequisite for making the forecasts about future population size and structure which should underpin healthcare planning (Grundy, 2004). Demography is premised on the study of information that is gathered from population census or vital statistic records.
