Longevity claims

Longevity claims are unverified claims to extreme age that cannot be independently corroborated according to the standards of Age Validation research.

For the purposes of studying supercentenarians, longevity claims are defined as claims 115-129, which fall into the realm of highly unlikely but still possible age ranges.

Some other definitions of longevity claims may also be used, such as claims 110+ or even any longevity claim that's not validated. The age limit criteria is only used for statistical convenience. A man claiming to be 96 but who doesn't have a birth record can be seen as a longevity claim. However, one must consider "extreme longevity claims" to be a much higher age than what is fairly common worldwide. For that subset, 115+ tends to be a good minimum starting point, as it is at the "average maximum" line of the human lifespan.
