What are uninsured persons called?

People are uninsured for a variety of reasons. Some have conditions that insurance will not cover. Sometimes, insurance companies drop people because their condition will be too expensive. Recently insurance companies have been exposed as dropping people just to improve their earnings. Some companies no longer offer insurance to their employees. When people lose their jobs, they also lose their insurance. Many people can't afford insurance. I think uninsured people should be called unfortunate, especially in a country that spends tax dollars on research that the majority of the citizens can not take advantage of.
