Officials say 38 percent of the United States population has type O positive blood, making it the most common of the eight blood types. Since 84 percent of the U.S. population can receive type O positive blood, there is a steady demand for it from hospitals and patients. People with type O negative blood are particularly in demand because they are the "universal donor." It means that people of all blood types can receive type O negative blood safely, so it is used during life-threatening emergencies or when the matching blood type is in short supply. ----- Type O negative is roughly 15 percent of the population
