How Income Level affects Life Expectancy
This article affirms that a defined state of relationship between income and life expectancy is unlikely to be experienced in the U.S. Rather, the relationships vary from area to area. The implication is that a number of moderating factors exist and account for this variation, yet an in-depth analysis of the same factors explaining the differences in relationships between income and life expectancy (from one area to another) is yet to be conducted. The study proceeds to highlight that across the income groups, differences in longevity tend to increase in some areas and decrease in others. Overall, the study indicated that a non-uniform state of relationship between life expectancy and the level of income among residents was evident in the U.S., with a particular emphasis on the period stretching from 2001 to 2014.
