Life insurance is a financial contract and risk management instrument studied within fields such as actuarial science, economics, and finance, primarily investigating the quantification, pricing, and management of mortality risk to provide financial indemnification upon the death of an insured individual, thereby serving as a mechanism for wealth transfer, estate planning, and long-term financial security. This concept examines the probabilistic nature of human longevity, the design of policy structures, regulatory frameworks, and the socio-economic implications of transferring mortality risk from individuals to insurers.
