CASE STUDY;The people of a country are its consumers. They provide the labour force for production. A study of the population of any country, therefore will give a birds eye view of the community for which the economic system must provide, and also of the size and nature of the available labour force. At any one time the structure of the population is largely the result of demographic factors prevailing some fifty years earlier. In Africa, the improvements in medical knowledge and increased application of that knowledge have been able to produce dramatic reductions in death rates, so that the average life expectancy in Africa may well have been doubled over the past half-century, application of the improvements in technical knowledge has not been able to produce equally dramatic changes in the supply of food. b. Causes of changes in the Rate of Growth Changes in population come about in two ways; (i) by movements in crude death rates, and (ii) by migration. The crude birth rate is usually expressed as the number of births per annum per thousand of the population and the crude death rate is the number of deaths per thousand of the population per annum. The natural growth rate will be the difference between these two rates, Natural Growth Rate = Birth Rate - Death Rate Thus if a country has a birth rate of 40 per 1000 and a death rate of 20 per 1000, its population has a natural growth rate of 2 per cent per annum.
