Preston Curve in Economics | UPSC

While the Preston Curve highlights a correlation between income and life expectancy, further research is needed to determine the extent to which income inequality within a country affects the overall curve.

The flattening of the Preston Curve at higher income levels suggests that factors beyond just wealth, such as access to quality healthcare and social safety nets, play a significant role in life expectancy at developed nations.

Analyzing historical shifts in the Preston Curve can provide valuable insights into the impact of public health advancements and economic development strategies on population longevity.

Deviations from the expected Preston Curve in specific countries might be explained by unique factors like environmental pollution, political instability, or specific disease burdens.

The Preston Curve can be a valuable tool for policymakers when evaluating the potential impact of economic interventions on population health and well-being.
