When I learned that access and affordability of insurance was a key theme of this issue, I decided to write about the impact that data-driven pricing may have on individuals’ ability—particularly higher-risk individuals—to obtain coverage. The insurance industry stands at a pivotal moment, shaped by the rapid emergence of new data sources and technological advances. These forces are revolutionizing how we price coverage and, more profoundly, challenging the foundational principle of insurance as a collective enterprise. In this article, I discuss these changes, explore their implications, and highlight the vital role actuaries must play in guiding the responsible evolution of risk segmentation.
The past decade has witnessed an explosion in the variety and volume of data available to insurers. Information from connected vehicles, wearable health devices, smart home sensors, and even social media feeds now enables actuaries and underwriters to predict risk with unprecedented precision. For instance, automobile insurers can assess driving habits in real time, and health insurers may monitor activity trackers to gauge wellness. These innovations promise more tailored products and fairer pricing for consumers, but they also raise profound questions about equity and the social purpose of insurance.
Traditionally, risk classification depended on broad groupings—age, occupation, geographic location, and other demographics. Today, sophisticated analytics and machine learning are driving much finer segmentation. Actuaries can now identify risk profiles at the individual level, adjusting premiums to reflect unique circumstances. While this enhances predictive accuracy and helps prevent adverse selection, it may erode the communal nature of insurance.
At its essence, insurance is a system of risk pooling in which individuals contribute to a shared fund so losses are distributed among all. This principle has fostered social solidarity and financial security for centuries. However, as risk classification grows more refined, the pool itself fragments. Lower-risk individuals pay less; higher-risk individuals may face increased premiums or even exclusion. The foundation of insurance as a mechanism for collective risk-sharing is gradually eroding.
If this trend continues unchecked, insurance may increasingly resemble individualized savings programs rather than traditional risk-sharing models. Each person’s premium could mirror their own expected losses, with little cross-subsidization among members. Such a shift would fundamentally alter the role of insurance—reducing its capacity to protect vulnerable groups and distribute risk broadly. For consumers, the change might bring transparency and personalization, but also raise the risk of insufficient protection for those who need it most.
Actuaries, by virtue of our strong quantitative skills, ethical standards, and professionalism structure, are especially well-equipped to address the challenges and opportunities of this new era. Our expertise allows us to evaluate complex data, model risks accurately, and understand the nuances of risk segmentation. Equally important, our professionalism framework emphasizes fairness, integrity, and public interest. As the insurance landscape evolves, actuaries should be at the forefront—ensuring innovation is balanced with actuarial soundness, privacy, and accessibility.

Novel data sources and refined pricing techniques can improve efficiency and reduce fraud, but they also risk undermining the social contract embodied in insurance. It is essential that we foster collaboration among insurers, regulators, consumer advocates, and actuaries to ensure progress does not come at the cost of inclusivity or fairness.
The insurance industry is rapidly evolving, and the decisions we make now will shape its future for generations. As president of the Academy, I urge professionals, policymakers, and the public to engage in thoughtful dialogue. We must embrace innovation, safeguard foundational principles, and rely on actuaries to steer the responsible evolution of risk segmentation. In doing so, we can ensure that insurance remains resilient, relevant, and a pillar of social protection in the face of change.
