Social insurance

Social insurance refers to a social and economic system that provides income or compensation to a population that is incapacitated, temporarily out of work, or has suffered a loss due to health reasons. The main programs of social insurance include pension insurance, medical insurance, unemployment insurance, work injury insurance, and maternity insurance.

Social insurance programs are run by the government, which forces a certain group of people to pay a portion of their income as a social insurance tax to form a social insurance fund. Under certain conditions, insured persons receive a fixed amount of income or compensation for losses from the fund. It is a redistributive system whose goal is to ensure the reproduction of material and labor and the stability of society.
