There is a high fertility rate that allows people to have as many children as they want because culture or religion allows them. Besides, these children are a source of labour in households. In addition, most of the people do not even know or practise family planning since such facilities are not available or the people are ignorant. Again, people tend to have many children because they are afraid that some of the children may due to hunger or diseases that are prevalent since health facilities are not well developed. Because of that people have to bear more children to beat the Crude Death Rate. However, as population’s economic, education, food and health conditions improve, according to Rodrigue (2012) and University of Michigan (2006), Crude Birth Rate starts decreasing in stages two, three; and very low in stage four where a country is now highly developed. In stage four, people opt for very small families because of the rising costs and health conditions are so good that deaths are minimised.
In addition, Crude Death Rate (CDR) is also very high at the beginning because of problems such as poor diets, health services and education, which are highly characteristic in a developing (pre industrial) country. As such, people tend to bear more children to try to cover for the losses they get through deaths. However, as health services and facilities; food quantities and quality together with economy improve, Crude Death Rates start decreasing in stages two and three until they become very low in the fourth stage, where a country attains industrialized status just like Crossman (2014) and Rodrigue (2012) agree.
Whilst there are high birth and death rates at the beginning, birth rate is basically higher to try to cover up death rates. This creates a balance in the population. Similarly, very low death rates make the population keep growing steadily since birth rate is surpassing death rate in stage four. As
