Measuring Disease Frequency In 2000, the crude mortality rate from all causes for Haiti (a very impoverished country) was 6.0 deaths per 1,000 persons. In contrast, the crude mortality rate from all causes for the United States was 10.4 deaths per 1,000 persons. Then respond to the following: What are some of the factors you would want to consider in assessing such a difference in mortality? Discuss possible explanations as to why the crude mortality rate is lower in Haiti than in the United States.
