One who calculates insurance risks and premiums. Actuaries compute the probability of the occurrence of such events as birth, marriage, illness, accidents, and death. They also evaluate the hazards of property damage or loss and the legal liability for the safety and well-being of others. Usually employed by insurance companies, actuaries set premium rates based on statistical studies, establish underwriting procedures, and determine the amounts of money required to assure the payment of benefits.
