Mortality tables are an important tool in finance that helps us determine life expectancy. These tables provide statistical data about the likelihood of a person reaching a certain age based on factors such as gender, occupation, and lifestyle. By understanding mortality tables, we can better assess the risks associated with financial investments, such as life insurance policies and retirement plans. They also play a crucial role in predicting future financial obligations, such as pension plans for employees. In short, mortality tables are a key component in making informed financial decisions and planning for the future.
