Currently, the world's oldest "verified" living person is a lady named Besse Cooper who lives in Monroe, Georgia. She was born on August 26, 1896 and is 114 years old.
Mrs. Cooper is recognized as such because she's able to provide a birth certificate, among other required material, to qualify as the oldest living person in the world.
However, Mrs. Rebecca Lanier was born black in Mississippi 119 years ago, during a time when black people weren't provided birth certificates.
