Susannah Mushatt Jones, the world's oldest person, has died in New York at the age of 116.
Ms Jones, who was affectionately known by family and neighbours as Miss Susie, died on Thursday night at a public housing facility for seniors in Brooklyn where she had lived for more than three decades, according to Robert Young, a senior consultant for the Los Angeles-based Gerontology Research Group.
She had been ill for the past 10 days, he said.
Her death leaves a 116-year-old woman from Verbania, Italy, Emma Morano, as the world's oldest person, and the only living person who was born in the 1800s, Mr Young said.
Moreno was just a few months younger than Jones, according to the organisation, which attempts to track all living supercentenarians.
Ms Jones was born in a small farm town near Montgomery, Alabama, in 1899.
She was one of 11 siblings and attended a special school for young black girls. When she graduated from high school in 1922, Ms Jones worked full time helping family members pick crops.
She left after a year to begin working as a nanny, heading north to New Jersey and eventually making her way to New York.
"She adored kids," Lois Judge said of her aunt in a 2015 interview. Ms Jones never had any children of her own and was married for only a few years.
Family members said last year that they credited her long life to love of family and generosity to others.
Ms Judge said at the time that she believed it helped that her aunt grew up on a rural farm, where she ate fresh fruits and vegetables that she picked herself.
After she moved to New York, Ms Jones worked with a group of her fellow high school graduates to start a scholarship fund for young African-American women to go to college. She also was active in her public housing building's tenant patrol until she was 106.
Ms Jones became Guinness World Records' official oldest person when 117-year-old Misao Okawa died in Tokyo last year.
