Demographic change deals with the transition of the population structure. The most markedly transition is the change from higher births and deaths to lower births and lower deaths. This transition actually refers to a set of interrelated transitions
Ghana's population growth shows signs of this state of demographic transition. This has generated a series of changes in our population structure. There is a corresponding mortality transition, fertility transition, age transition (with higher populations in rural areas), leading to migration transition (the redistribution of the population); this further creates the urban transition and eventually family and household transition.
That Ghana is also going through this series of transitions, presupposes that the population is being redistributed. This means the emphasis of economic policy would have to change. In this regard the needs of the aged and school-going children are particularly called into question.
The US Census Bureau International database projects Ghana's population at 24.3 million in 2010 and 26.6million in 2015 and 30.9million in 2025. This comes with a corresponding growth rate of 1.9 and 1.7 and 1.4. Life Expectancy at birth may increase from 63years in 2015 to 67 years in 2025. Net migration is in the negative. This means, natural population change is the main driving force behind our population growth. Death rates may decrease from 10 per 1000 persons in 2005 to 8 in 2015 and 7 in 2025. Total Fertility rates may decrease from 4.1 in 2005 to 3.1 in 2015 and 2.5 in 2025.
