Investigating the Use of Disease Progression Demographics in Health Care. This paper focuses on two current fields of demographics and health care. The first is the rising frequency of obesity within the population and how increasing frequency of obesity is likely to affect the statistics pertaining to diseases such as heart disease and diabetes. The second area of demographics research is that of smoking, where a strictly environmental activity is likely to replace heart disease as the primary cause of death within the next two decades.
