Life-years lost (LYL) is a metric used in public health to quantify the impact of premature mortality on a population. It measures the total number of years of life lost due to deaths that occur earlier than a predefined age, often the average life expectancy. This metric helps to highlight the burden of diseases, accidents, or health conditions that lead to early death.
