The Society of Actuaries (SOA): Life, Health, and Long-Term Risk #
Founded in 1949 through the merger of the Actuarial Society of America and the American Institute of Actuaries, the SOA represents the larger actuarial organization globally, with over 31,000 members worldwide. The SOA’s primary focus encompasses life insurance, health insurance, retirement benefits, and investment management – areas characterized by long-term financial commitments and complex mortality and morbidity modeling.
Core Practice Areas #
Life Insurance and Annuities: SOA actuaries develop sophisticated pricing models for life insurance products that may extend over several decades. This involves analyzing mortality trends, creating life tables, calculating policy reserves, and managing the delicate balance between competitive pricing and long-term profitability. The work requires deep understanding of demographic trends, medical advances, and their impact on longevity projections.
Health Insurance: With healthcare costs representing one of the most volatile and complex areas of actuarial practice, SOA health actuaries analyze medical cost trends, develop utilization models, and create pricing structures for individual and group health insurance products. This field has become increasingly sophisticated with the integration of big data analytics and machine learning techniques to predict healthcare utilization patterns.
Retirement and Pension Systems: SOA pension actuaries work with some of the most complex long-term financial models in the profession, calculating funding requirements for defined benefit pension plans, designing defined contribution programs, and assessing the financial sustainability of retirement systems. This work often involves collaboration with government entities, large corporations, and consulting firms.
Investment and Risk Management: SOA actuaries increasingly work in investment management roles, applying their risk assessment skills to portfolio management, asset-liability modeling, and enterprise risk management. This emerging field combines traditional actuarial techniques with modern financial theory and quantitative analysis.
Typical Work Environment and Responsibilities #
SOA actuaries typically find employment in life insurance companies, health insurers, consulting firms, government agencies, and investment management companies. Their day-to-day responsibilities often include:
- Developing complex financial models that project cash flows over decades
- Analyzing large datasets to identify trends in mortality, morbidity, and lapse rates

The Casualty Actuarial Society (CAS): Property, Casualty, and Short-Term Risk #
Established in 1914, the CAS is the older of the two major North American actuarial organizations, with approximately 9,000 members. The CAS specializes in property and casualty (P&C) insurance, also known as general insurance, focusing on shorter-term risks typically covering one year or less. This field encompasses a broad range of insurance products designed to protect against property damage, liability claims, and various forms of financial loss.
Core Practice Areas #
Personal Lines Insurance: CAS actuaries working in personal lines develop pricing models for auto insurance, homeowners insurance, and personal umbrella policies. This work involves analyzing driving records, credit scores, geographic risk factors, and property characteristics to create sophisticated rating algorithms that accurately reflect individual risk profiles.
Commercial Lines Insurance: Commercial insurance represents one of the most complex areas of P&C actuarial work, involving the analysis of risks for businesses ranging from small enterprises to multinational corporations. This includes workers’ compensation, commercial auto, general liability, professional liability, and cyber insurance – each requiring specialized knowledge and unique analytical approaches.
Specialty Lines and Emerging Risks: CAS actuaries often work with specialty insurance products such as aviation insurance, marine insurance, earthquake coverage, and the rapidly growing field of cyber liability insurance. These areas require deep technical knowledge and the ability to model risks with limited historical data.
