Actuaries determine risk and probability in a wide range of career fields. They analyze past data and use that information to determine how to prevent harmful events from occurring in the future.
An example of someone who would use actuarial science daily would be an insurance actuary, who calculates how likely a person is to have an accident in the future and how much damage that accident might cause. They are then able to calculate the expected amount that a person should pay insurance to cover that future event.
Actuaries might also work within organizations to determine pensions, employee benefits or stock market investments. Or they might help identify economic, financial and geopolitical risks that may affect a company’s objectives and work with the company to mitigate those risks.
