Risk Pool

A risk pool is the collective group of insured individuals or entities whose premiums are aggregated so that the losses of the few are paid by the contributions of the many.

Definition

A risk pool is the foundational mechanism of insurance: a large number of people or businesses pay premiums into a shared fund, and that fund pays claims for those who suffer covered losses. The larger and more diverse the pool, the more predictable and stable the loss experience becomes. Insurers use actuarial data to price premiums so the pool remains solvent after paying claims and administrative costs. High-risk individuals can strain a pool, which is why insurers screen applicants through underwriting. State-run residual market pools (e.g., FAIR Plans) exist to cover applicants who cannot obtain coverage in the voluntary market. Understanding risk pools explains why your premium can rise even if you personally file no claims — widespread losses in your pool affect everyone's rates.
