Understanding actuarial science
Actuarial science attempts to quantify the risk of an event occurring using probability analysis so that its financial impact can be determined. Actuarial science is typically used in the insurance industry by actuaries. Actuaries analyze mathematical models to predict or forecast the reasonableness of an event occurring so that an insurance company can allocate funds to pay out any claims that might result from the event.
For example, studying the mortality rates of individuals of a certain age would help insurance companies understand the likelihood or timeframe of paying out a life insurance policy.
Actuarial science became a formal mathematical discipline in the late 17th century with the increased demand for long-term insurance coverage. Actuarial science spans several interrelated subjects, including mathematics, probability theory, statistics, finance, economics, and computer science.
Applications of actuarial science
The following are instances where actuarial sciences apply.
Insurance
In traditional life insurance, actuarial science focuses on the analysis of mortality, the production of life tables, and the application of compound interest. As a result, actuarial science can help develop policies for financial products such as annuities, which are investments that pay a fixed income stream. Actuarial science is also used to determine the various financial outcomes for investable assets held by non-profit corporations as a result of endowments.
In health insurance, including employer-provided plans and social insurance, actuarial science includes analyzing rates of:
- Disability in the population or the risk of a certain group of people becoming disabled
- Morbidity or the frequency and the extent to which a disease occurs in a population
- Mortality or mortality rate, which measures the number of deaths in a population that result from a specific disease or event
- Fertility or fertility rate, which measures the number of children born
Pensions
In the pension industry, actuarial science compares the costs of alternative strategies with regard to the design, funding, accounting, administration, and maintenance or redesign of pension plans. Actuaries may also work in the public sector to assist with proposed changes to Social Security, Medicare, or other programs.
Universities and professional certifications
According to the Bureau of Labor Statistics, the number of actuaries employed is expected to grow 23% from 2022 to 2032. For this reason, many universities offer educational degrees and courses on actuarial science. In addition, there are professional designations for those interested in pursuing the field.
The Society of Actuaries identifies and reports colleges that meet one of three levels of recognition:
- UCAP-Introduction Curriculum
- UCAP-Advanced Curriculum
- Center of Actuarial Excellence
As of December 2022, there are roughly 25 Center of Actuarial Excellence schools across the United States, Canada, Australia, Singapore, the United Kingdom, and China.
There are a number of different professional designations an actuary can pursue to further gain credibility and proficiency in their field. The Casualty Actuarial Society offers the Associate (ACAS) and Fellow (FCAS) membership levels, each with escalating requirements. The Society of Actuaries promotes several different actuarial exams to demonstrate competency in the field.
FAQs in actuarial science
What is the primary role of actuaries in the insurance industry?
Actuaries in the insurance industry primarily assess and manage financial risks. They use mathematical and statistical methods to predict the probability of certain events, such as accidents or illnesses, and allocate funds to cover potential claims. Actuaries play a vital role in helping insurance companies determine appropriate premiums and maintain financial stability.
How long does it take to become a certified actuary?
Becoming a certified actuary is a rigorous process that can take several years. It typically involves obtaining a bachelor’s degree, passing a series of challenging actuarial exams, and gaining practical experience. The duration may vary, but it often takes around a decade to complete all the necessary requirements.
What industries besides insurance and pensions use actuarial science?
Actuarial science is applied in various financial industries beyond insurance and pensions. It is used in healthcare, financial organizations, and even in analyzing risks associated with investments. Actuaries contribute their expertise to assess the financial implications of uncertain future events in these sectors.
What are some key challenges actuaries face in their profession?
Actuaries face challenges related to the complexity of their work, including the difficulty of actuarial exams, the need for ongoing professional development, and the responsibility of making critical financial decisions. Additionally, they must keep up with changes in regulations and adapt to advancements in technology and data analytics.
Are there different types of actuarial certifications, and how do they differ?
Yes, there are different types of actuarial certifications offered by organizations like the Casualty Actuarial Society (CAS) and the Society of Actuaries (SOA). These certifications vary in terms of requirements and areas of focus. For example, CAS offers the Associate (ACAS) and Fellow (FCAS) designations with a focus on property and casualty insurance, while SOA offers designations like Associate of the Society of Actuaries (ASA) and Fellow of the Society of Actuaries (FSA), covering various areas of actuarial practice, such as life insurance, pensions, and more.
The bottom line
Actuarial science is the study of mathematically predicting the probability of something happening in the future and assigning that outcome a financial value.
