There are only two living people now who were born in the 19th century - both of whom were born in 1899. Just two years ago, that number was six. It's likely that there will be nobody born in the 19th century who is still living in a year or two from now.

Yup... there are two of them. Susannah Mushatt Jones (b. 6 July 1899) from the United States and Emma Morano (b. 29 November 1899) from Italy. The former will be 116 years old, in two weeks from now.
One interesting fact which I have noticed is that 20 out of the 45 oldest living people (as of now) are from Japan. What is the secret behind their longevity? Organic food? or better medical care?
