One of the reasons that the statistical oddity of Jeanne Calumet as an outlier may not mean much is that maybe the main reason she doesn't have much competition is simply that there aren't many alleged super-centenarians with good documentation. There may well be quite a few other people who lived to 120+ but they can't prove it and so nobody talks about them. I know of a woman in my town in rural Brazil who claimed to be 124 before she died, but she had no documentation and here even today there are quite a few people without birth certificates! Now that people over 110 were all born in the 20th century more and more actually can be verified, so the gap is beginning to close. A lot more people seem to be living into their 110s, but it's really hard to say how much of that is due to people's better health and better health care for the very aged, and how much is simply due to the increased verifiability.
