Researching the correlation between wealth and health, a study by Kyriopoulos et al. 2024 delves into the relationship and its variations across countries. The concentration index (CI) is used to measure this, illustrating the inequality in health status based on wealth rankings. Using data from the Health and Retirement Survey (HRS) and Survey of Health, Ageing, and Retirement in Europe (SHARE), the study finds that wealth-related inequalities in health exist in high-income countries, with the US showing higher levels of inequality compared to Europe. The findings remained consistent over the study period for all countries involved.
