What is Actuarial Science?
Discipline used to determine risk in finance and insurance through statistics and mathematical models. Individuals who become actuaries must prove their abilities through testing to obtain certification. The discipline encompasses probability and statistics, computer programming, finance and economics. In 2010, actuarial science was rated the number one job in the United States according to a study by CareerCast.
Actuarial science is the science of applying mathematical and statistical models to improve financial decision-making by evaluating the financial implications of uncertain future events.
An actuary is a professional concerned with the financial evaluation of risk. They design and administer insurance programs, pensions, government welfare plans and similar financial plans. The main responsibility of actuaries is to ensure that these plans operate on a sound financial basis. To do this they use many areas of mathematics (for example: probability theory, statistics, the theory of interest) as well as general principles of economics and finance.
Actuaries are experts in risk management. In particular, actuaries
are involved in the design, pricing, financing, and operation of benefit
plans which protect people from risks of injury, illness, death,
property damage, and the loss of income due to unemployment or
retirement. Actuaries use mathematical skills to create and manage
programs that reduce the adverse financial impact of life's expected and
unexpected events, including financial risks from investment.
