Actuary Career

ActuariesActuaries use statistical formulas and techniques to calculate the probability of events such as death, disability, sickness, unemployment, retirement, and property loss. Actuaries develop formulas to predict how much money an insurance company will pay in claims, which determines the overall cost of insuring a group, business, or individual. Increase in risk raises potential cost to the company, which, in turn, raises its rates. Actuaries analyze risk to estimate the num­ber and amount of claims an insurance company will have to pay. They assess the cost of running the business and incorporate the results into the design and evaluation of programs.

Casualty actuaries specialize in property and liability insurance, life actuaries in health and life insurance. In recent years, there has been an increase in the number of actuaries—called pension actuaries—who deal only with pension plans. The total number of actuaries employed in the United States is approximately 18,000.

Actuary Career History

The term actuary was used for the first time in 1762 in the charter for the Equitable Society of London, which was the first life insurance company to use scientific data in figuring premiums. The basis of actuarial work was laid in the early 17th century when Frenchmen Blaise Pascal and Pierre de Fermat derived an important method of calculating actuarial probabilities, resulting in what is now termed the science of probability.

The first mortality table was produced in the late 17th century, when Edmund Halley noticed the regularity of various social phenomena, including the excess of male over female births. Halley, an English astronomer for whom Halley’s comet is named, is known as the father of life insurance. As more complex forms of insurance were developed in the 19th century, the need for actuar­ies grew.

In 1889, a small group of qualified actuaries formed the Actuarial Society of America. Two classes of mem­bers, fellows and associates, were created seven years later, and special examinations were developed to determine membership eligibility. Forms of these examinations are still used today. By 1909 the American Institute of Actu­aries was created, and in 1949 these two groups consoli­dated into the present Society of Actuaries.

In 1911, the Casualty Actuary Society was formed in response to the development of workers’ compensa­tion laws. The compensation laws opened up many new fields of insurance, and the Casualty Actuarial Society has since moved into all aspects of property and liability insurance.

Accounting CareersOASDI (Old Age, Survivors, and Disability Insur­ance), now known as Social Security, was created in 1935 and expanded the work of pension actuaries. The cre­ation of this program greatly impacted the development, philosophy, and structure of private pension programs. The American Society of Pension Actuaries was formed in 1966; its members provide services to over 30 percent of the qualified retirement plans in the United States.

The first actuaries were concerned primarily with sta­tistical, mathematical, and financial calculations needed in the rapidly growing field. Today they deal with prob­lems of investment, selection of risk factors for insur­ance, agents’ compensation, social insurance, taxation, development of policy forms, and many other aspects of insurance. Once considered mathematicians, actuaries are now referred to as “financial architects” and “social mathematicians” because they use their unique com­bination of numerical, analytical, and business skills to solve a variety of social and financial problems.
