3. #2) Measuring degree of change. In general terms there are two approaches we can use to measure the degree of change.In general terms there are two approaches we can use to measure the degree of change. The first approach is “absolute” in which we compare the actual differences between two sets of numbers. This shows the true change in the data, but makes it difficult to compare large populations to small populations.The first approach is “absolute” in which we compare the actual differences between two sets of numbers. This shows the true change in the data, but makes it difficult to compare large populations to small populations. The second approach is relative in which numbers are considered in comparison to some base number. This allows for comparisons between populations of any size.The second approach is relative in which numbers are considered in comparison to some base number.

Most of the nations making significant progress could be described as newly- industrialized.Most of the nations making significant progress could be described as newly- industrialized. Unfortunately, Nigeria which is facing many problems is also one of the nations making the least progress. This does not suggest future improvements.Unfortunately, Nigeria which is facing many problems is also one of the nations making the least progress. This does not suggest future improvements. Relative First world nations such as Italy and Japan will be facing significant crisis as these nations being the process of depopulation. China continues to improve its population outlook, although labour shortages may result. Although nations such a India and Egypt will see improvements in their population numbers, Nigeria will face a difficult future as its population will increase only slightly less rapidly than at present.
