According to the Standord University School of Medicine, the rarest blood type is AB Rh Negative, with only .6% of the United States having this type. That is roughly 1 out of every 167 people. However, some suggest an ultra-rare type known as "Bombay Blood." There have only been a handful of reported cases of humans known to have this blood type. This could be the result of a slight mutation, though.
