The theory is that population growth has a positive relationship with child mortality. In order to know if the theory is correct, one has to define all the parts of the theory, the concepts, and the indicators. One needs to make sure that the theory and concept are testable, logically sound, communicable, parsimonious, and general. The theory I have presented may be all these things except one; it is not very simple. Theories are created to describe, explain, and build cause and effect relationships. As mine can both describe and explain, it lacks a cause and effect relationship.
The two key concepts that are related to one another in the theory are life expectancy and the fertility rate. Life expectancy …show more content…
One has to include all the ages of the population and realize how life expectancy would limit that number to an extreme degree. Population counts elderly, adults, teens, children, toddlers, and infants while life expectancy is limited to children under a year old. Population density and total population are different than population growth. Population density is the amount of people per unit of area or volume, total population is the number of individuals in an area in question, and population growth is the growth in population in a given area over a span of time. Some indicators of fertility rate are nutrition, health economics, maternal health, etc. Nutrition plays a huge role in fertility for both the mother and the child. If the mother is not getting enough nutrients during the pregnancy, then that could lead to a miscarriage or the child being born premature or malnourished. Health economics can hinder a fertility rate due to the fact that in places that spend more money on health care, there can be more access to birth contraceptives, disease prevention, and …show more content…
The results of the scatter plot show that population growth and child mortality have no relationship at all. Consequently, they do not provide evidence to support my hypothesis. There might be missing factors that need to be accounted for to fully examine the theory. The theory might be spurious in its own right. It may be proven wrong all together or maybe another theory can better represent the correlation between population growth and child mortality. Maybe those two factors are not cause and effect maybe it is something else with population growth and another idea with child mortality.
There may even be an intervening factor, such as water scarcity and other cultural and environmental aspects. For example, water scarcity and lack of resources in general can lead to people not having enough nutrients to support another life. Thus, leading to a higher mortality rate. Also, many different cultural practices can lead to a higher child mortality rate. For instance, in Somaliland, young women have their genitals mutilated in order to better control population growth and child mortality. In addition, other environmental aspects could possibly play an important role in the factors as well. The worse the environment is, the less citizens have access to contraceptives. Africa can illustrate the model of that concept,
