What is an actuary?

An actuary is a professional who evaluates and helps manage risks faced by individuals, businesses and governments. For example, health-care actuaries work to assess the costs of a range of health-care risks from individual illnesses to pandemics. Property and casualty actuaries develop auto insurance premium rates. And government actuaries in Washington, D.C., evaluate the long-term costs of Social Security in light of the retirement of the Baby Boomer generation and their longer life expectancies.

Do you think most people know what an actuary is?

Probably not, and I do frequently get asked about it. It's kind of an occupational hazard of being an actuary! But, everyone is affected by the work that actuaries do. Anyone who carries auto insurance, for example, pays a premium developed by actuaries who evaluate the effects of pooling the risks of accident or injury for a large group of policyholders. Knowing that, it should come as no surprise that actuaries are working hard to evaluate the risks to drivers, manufacturers, and technology companies of the emerging phenomenon of driverless cars!

Do you get asked that question all the time?

Of course! But that's okay. Inevitably the discussion gets around to the things we do that matter to people day-to-day. Life and health insurance, auto insurance, financial security — all these systems, which we tend to take for granted — they all WORK because of the efforts of actuaries.

What’s a typical day like for you?

I talk to businesses and help them identify and solve problems related to employee benefits – pensions and health care. I work with my team to develop models of pension programs, for example, so as to help forecast what a long-term pension program should cost in today's dollars.



What type of skill set do you need to be an actuary?

Most actuaries are schooled in mathematics, probability and statistics — and along the way, they pick up general business and finance skills. Actuaries study the business application of all these skills and then they will typically refine what they've learned with solid, on-the-job training in the insurance, pension, or health-care fields.
