Health Adjusted Life Years 

Health-Adjusted Life Years measure the health of a population, to estimate burden of disease. HALYs are used to measure the combined effects of mortality and morbidity in populations; comparisons between illnesses or interventions. They are commonly used to compare the cost-effectiveness of different health interventions. HALYs are based on epidemiological data, hence their accuracy depends from the completeness and accuracy of the data[37]. [37] https://www.who.int/gho/mortality_burden_disease/life_tables/hale/en/
