The insurance sector covers a very wide range of activities. From a technical standpoint, it encompasses areas that touch many aspects of everyday life, such as property and casualty insurance (e.g., home multi-risk, natural disasters), civil liability (e.g., automobile), health or personal protection, as well as retirement and savings. From a client standpoint, policyholders include individuals, professionals, small businesses, and large corporations (fleets, industrial risks, group insurance, etc.). From a commercial standpoint, the sector relies on highly diverse intermediaries: in-house networks, tied agents, brokers, and various service providers.
This diversity is also reflected in the legal forms of the entities providing coverage: joint-stock companies remunerating shareholders, mutual insurance companies governed by the Insurance Code, provident institutions under the Social Security Code, or “Mutuelles 45” governed by the Mutuality Code. Some are highly specialised, while others are broadly diversified — whether in terms of activities, geographical scope, or customer segments.
The diversity of activities and actors reflects the importance of insurance mechanisms in the functioning of industrial and post-industrial societies as tools for managing the risks they generate. Present in both public and private insurance systems, these mechanisms have traditionally been guided by principles of solidarity and various pooling techniques. In recent years, however, insurance appears to be undergoing profound transformations due to evolving economic activities leading to the emergence of new risks, as well as the maturation of technologies that challenge long-standing solidarity principles and pooling techniques.
The emergence of new risks can be observed at two levels:
Big data technologies, which enable both mass data collection and processing through increasingly powerful algorithms, have further reshaped the insurance landscape. With increasingly granular information, it is now possible to apply statistical models at the individual level, a practice unimaginable in earlier periods.
