What are the differences between Epidemiology and Actuarial science?

Question

But is it the same type of math? Statistics?

Answer 1

Unless I'm misunderstanding Epidemiology, these are pretty different fields.

Actuarial science does involve math concepts, and so does Epidemiology, but the applications are somewhat different.

Actuarial science essentially addresses the risk component in fields like insurance, pensions, finance, etc. With large amounts of money like insurance policies (can enter the millions) and how much the public depends on insurance when the unplanned things in life happen, risk analysis is important for the survival of these fields.

Epidemiology, as Wikipedia tells me, "is the study of factors affecting the health and illness of populations, and serves as the foundation and logic of interventions made in the interest of public health and preventive medicine."

There is certainly an element of risk analysis present in epidemiology, but as noted above, the applications of math to each of the fields are quite different. I'd also imagine that the mathematical models used in each field are pretty different as well.

Answer 2

Actuarial Science deals with insurance.
Epidemiology deals with the study of factors affecting health and illness of human population.

Answer 3

Nearly all disciplines use statistics, physics, chemistry, biology, psychology . . . but they study different things.
