Group insurance is an insurance that covers a group of people, for example the members of a society or professional association, or the employees of a particular employer for the purpose of taking insurance. Group coverage can help reduce the problem of adverse selection by creating a pool of people eligible to purchase insurance who belong to the group for reasons other than the wish to buy insurance, which might be because they are a worse than average risk. Grouping individuals together allows insurance companies to give lower rates to companies, "Providing large volume of business to insurance companies gives us greater bargaining power for clients, resulting in cheaper group rates."
