What are the economic factors affecting death of a person explain

Assessing the relationship between economic conditions and mortality is difficult for a number of reasons. First, the impacts of intermediate- and short-term economic changes may differ from those of more sustained changes, and empirical analyses of long-term impacts are challenging because of many intervening factors. Second, confounding and complex interactions may mask effects. For example, economic deprivation may be correlated with education, making identification of the pure effects of economic well-being difficult to isolate.

Moreover, different demographic groups may experience economic conditions differently, and economic effects may interact with other time-varying contextual and environmental factors, such as the availability of opioids. For example, economic factors may give rise to physical and psychological pain, but the connection between that pain and mortality may reflect the introduction of opioids. Thus the combination of pain and opioids may have created conditions that led to significant mortality, while the absence of either might have greatly dampened the dramatic rise in mortality that occurred.

Finally, the effects of changes in economic conditions may vary based on the reasons behind the changes. The effects of plant closings, for example, may differ from those of cyclical recessions. Likewise, broad-based economic decline in communities may have a broader effect relative to individual economic setbacks.
