"One of the key opportunities associated with sequencing the genomes of Superercentenarins is the identification of predictors of living past 110 years old that can be observed early in life or in cells at any age, since those properties can be the basis of development of health-promoting regimens. Another opportunity derives from looking for environmental differences between families with similar genetic variants but very different outcomes with respect to a variety of aging traits. Hypotheses about such environmental differences could help build more focused health studies on large cohorts." - - Prof. George Church, Geneticist at Harvard University.

April 12, 2011; Donald B. Gennery, our GRG Biostatistician from JPL, has provided us with a US snapshot comparing genders throughout our full life history, starting at birth and going all the way to age 110 years (for the latest year for which data are available ). Therefore, this graph helps to explain the basis for the puzzling dramatic worldwide female longevity advantage amongst Supercentenarians (F:M > ~10:1).
Editorial: Note the curious discrepancy between males and females between ages 20 and 30 in which male mortality appears to plateau while this phenotypic leveling-off is not so conspicuous for females who encounter the risk of childbirth during this decade of their maximum fertility. Some part of the human genome seems to be busy calibrating (or fine tuning) the absolute numbers of males and females to become comparable at age ~20, so that, in principle, everyone has a partner/spouse, but how this might be done at the genetic level is not known. One could explain this phenotype by means of genes that manipulate the endocrine system (Testosterone:Estrogen ratio and monthly clocks in the pituitary gland) for each gender, but that wouldn't help us extend longevity by Hormone Replacement Therapy (HRT) during the extended grandparenting interval of menopause/andropause in which all sex-related hormones "flat line" and the addition of bio-identical estrogen after age 70 for women appears to be counterproductive (actually increases mortality) according to the latest data published in JAMA. So it seems that "demography is destiny."
January 19, 2010; Donald B. Gennery of JPL, and our GRG Biostatistician, has provided us with a White Paper entitled, Mortality Rate as a Function of Age
January 28, 2010; The worldwide geographical distribution of Supercentenarians, according
to their current residence, as of today's date, is shown as follows...
thanks to the efforts of Amr Saad.
Note: The pattern is conspicuously skewed by the unavailability of accurate birth record keeping in most countries in the Southern hemisphere back in the late 1800's. This is likely to change in the next few years, so we can expect to see a better representation from below the Equator, not because Supercentenarians are not there, but because we can start to validate them for the first time.
September 9, 2009; Here is a newer graph of the Numbers of Validated Living
Supercentenarians from 1966 to 2009 for 110, 112, 113, and 114 yo's, provided by Afrim Alimeti
of Lowell, MA based on source data provided by Louis Epstein of New York. The first graph is
at high resolution while the second graph shows one point per year...
The first and second graphs show yearly data points on the numbers of Supercentenarians over this time period for which we have data. The third graph plots 28 data points on a monthly basis from May 2007 to August 2009. One now more clearly observes the counterintuitive conclusion that the total numbers of living Supercentenarians have not continued to rise as one might expect based on the exponentially rising numbers of centenarians over the same time period, but somehow have become "flat." How could that be?
For the third graph, the upper line (blue) is the total number, while the next line (red) is for females, and the bottom line (green) is for men; the enormous gap between these latter lines (red minus green) is a complicated story to be discussed at a future time.
The points in the third graph cannot simply be pasted into the first or second graph at this time, since there are incompatible artifacts in the way the second-graph's data was compiled, which are not present in the earlier data. For example, these data do not include retrospective posthumously-identified cases. There are also problems associated with the fact that some of cases were not first identified until they were 111, 112, or older and since they were also alive at their earlier ages, the different age categories would have to be modified to incorporate the new data. Data from the second graph were a snapshot of the current level at the end of each month and not in the middle of the month. Finally, for the most recent month in 2009, it neglects cases that could have been added from the current pipeline of new cases waiting to be processed, but not yet entered for administrative reasons. We hope to produce a more uniform higher-resolution graph (without a gap in the time axis) for publication in the near future.
We will also have a detailed set of hypotheses for the trends we observe. One hypothesis is that trends in total numbers of living Supercentenarians will continue to rise indefinitely along with average life expectancies where any local statistical fluctuations in a particular year can be interpreted as due to chance. On the other hand, a second hypothesis could be that we are witnessing the emergence of a biological limit to the expression of the maximum potential human lifespan inherent in our species' genome regardless of the life-style choices made by individuals or the locations in which they live. The hypothesis that there exist longevity hotspots has been pretty-much discredited. It could be that we will never see anyone exceed Madam Jeanne Calment's Guinness Book of World Records record of 122 years 164 days in the next twenty-five years, unless, of course, biological engineers learn how to manipulate the rate of aging itself, in which case "all bets are off."
March 13, 2009; Here is a newer graph prepared by Donald B. Gennery of Social Security Data with a manual fit to Ruisdael's and Robert Young's data, spliced together at age 90 yo. The ambiguity in the five dots after age 115 lies in the small number of data points available needed to get a smoother curve. - - Steve Coles
Notice that it shows the mortality rate to be decreasing above about age 110, although this might not be statistically significant. The dots indicate the one-sigma limits of a straight-line fit (on the logarithmic plot) to Robert Young's data above age 111 (which is what the curve at those high ages mostly depends on). They might represent an overestimate of the uncertainty (because they do not include the influence of any data at younger ages), or they might represent an underestimate of the uncertainty (because they do not include the possibility of curvature at these high ages). You could briefly describe the dots by saying that they roughly represent the uncertainty due to the sparseness of the data at high ages. - - Don Gennery
March 19, 2008; Here are six charts prepared by Donald B. Gennery on March 11th and March 14th. During the last week there has been considerable dispute by GRG members in our Discussion Group as to why three consecutive points fall below the Linear Regression Line in the fourth chart. The primary mathematical interpretation says that these points being below the line is simply "due to chance." This explanation can not be ruled out because there is not sufficient statistical power in such a small population to claim otherwise; but the interpretation that there is some real, underlying genetically-based pathology (what has been called a fuzzy barrier that could explain it) is still worth being pursued. It may actually be a real phenomenon, but it might not. If so, there could be a peculiar genetic predisposition to kill off Supercentenarians starting at age 114 and ending at age 117 such that we should look for it in their DNA sequence (for example, a SNP in the TTR-gene that causes amyloidosis or telomere shortening leading to Uusual Interstitial Pneumonia) vs. those who escape through to age 119 (three persons so far) as a control group. But this hypothesis has no consensus yet. More will be posted about this debate later on as time goes on. - - Steve Coles
May 25, 2007; An important statistical question about the demography of Supercentenarians is whether their net numbers are increasing exponentially over time (synchronized, say, with the observed rise in the numbers of centenarians) or whether their numbers have remained relatively flat (with a small positive linear slope). Now, Mr. Robert Young, GRG Senior Claims Investigator of Atlanta, GA, and Miguel Quesada have graphed the numbers of Supercentenarians over the last 25 years between [1980 and 2006] to reveal the presence of any obvious trends above. They conclude: "We observe a steady rise from [1980 to 2000] followed by a modest leveling off since the turn of the century. However, missing cases, which are discovered subsequently, can bias these trends. Given that most of the missing cases are from 2000 onward, we speculate that the rise is continuing, albeit at a slower rate. However, we see that, theoretically, Table E, on this website, could easily have been over 100 cases if we could only validate every potential case at the same time. Yet, we notice that the greatest age -- 114 -- remains the same. Thus, we can conclude that most of the missing cases are for age range [110 - 111] yo."
January 24, 2010; Mr. Afrim Alimeti has sent us this Graph of the Average Age of the
Validated Oldest Living Persons by Gender covering the years [1971 - 2009].
Note that these average ages have remained relatively flat starting from the year 2000 to the present day. The Female advantage of approximately three years is also conspicuous on the graph. Independently on Table E, we see that there are approximately eight times as many Female Supercentenarians as Males, and this discrepancy has not been explained based on what we now know about our observed human longevity phenotype.
January 20, 2010; Dr. Greg Fahy has provided us with the following graphs of Supercentenarians 114 yo and above and 110 yo and above.
From a quick inspection of the first Graph, the seductive conclusion is that "human mortality flattens or plateaus at age 114 (and thus aging has been halted!). However, there is no consensus for this conclusion among the members of our GRG Discussion Group given that there are so very few points in this category to provide statistical significance. The real question is... Do these cases represent a statistical aberration (red herrings) or is there a biological basis in the human genome for these outliers not dying on a standard life-history schedule as they mathematically should? As a corollary, if there is a biological basis for this plateau, "Can the phenotype of aging can be conquered for ordinary people by finding out what these longevity-determining genes are and later figuring out how to manipulate them by genetic engineering?" - - Steve Coles
Dr. Fahy further says, "Both curves are based on the assumption of a constant mortality rate above a certain age. The data for survival from the age of 110 on indicate that the expected number of 122 year olds at any given time is equal to the number of 110 year-olds times 0.00038, or roughly 1/4, which amounts to roughly one 122-year-old every 4 years. The data for survival from the age of 114 indicate a much lower expectation of finding a 122-year-old because the size of the 114-year-old population is much smaller and the mortality rates of [114 - 116] year-olds is higher than expected from the trends from age 110 onward. Since the observed number of people aged 118 and over is so consistently above the projection obtained from the 114-year-old starting point, and since the curve fit from 110 onward accommodates both the [114 - 117] and the [118 - 122] age groups equally well, it seems likely that the higher mortality rate for [114 - 116] year- olds is just a statistical fluke, and that the true human mortality rate is really a constant from the age of 110 onward. What is not possible is that human mortality continues to increase exponentially from the age of 30 until the maximum lifespan is reached, as predicted by the Gompertz equation. The existence of a late-life mortality plateau for humans and other species implies that aging stops above a certain age. On the other hand, starting the analysis on the basis of Gompertz mortality continuing from a general trendline starting from the ages of 90 and below, one would predict that no one would exceed the Calment Limit over less then geological time periods"

Here's an Abstract: What if I told you I could add up to ten years to your healthy lifespan? A long healthy life is no accident. It begins with good genes, but it also depends on good habits. If you adopt the right lifestyle, experts say, chances are you may live up to a decade longer. So what's the formula for success? In recent years researchers have fanned out across the globe to find the secrets to long life. Funded in part by the U.S. National Institute on Aging [part of NIH], scientists have focused on several regions where people live significantly longer: (1) In Sardinia, ITALY, one team of demographers found a hot spot of longevity in mountain villages where men reach age 100 at an unusual rate; (2) On the islands of Okinawa, JAPAN, another team examined a group that is among the longest lived on Earth; and (3) in Loma Linda, CA, researchers studied a group of Seventh-Day Adventists who rank among America's longevity "all-stars." Residents of these three places produce a high rate of centenarians, suffer a fraction of the diseases that commonly kill people in other parts of the developed world, and enjoy more healthy years of life. In sum, they offer three sets of "best practices" to emulate. The rest is up to you.

Prof. Luca Deiana, a Researcher at the University of Sassari in Northwest Sardinia, said that he believes that "his island has the world's highest documented percentage of people who have passed the 100-year threshold." Part of his support comes from Duke University. They are focusing on the genetics of the "Y" Chromosome, since "the gender ratio of female:male centenarians in Sardinia is more like 1:1 as compared with the more typical ratio of 4:1 in the rest of the world.

February 7, 2008;
February 13, 2010; Assuming that there are 300 million U.S. Citizens, the chances of someone becoming a
centenarian is 1:80 [*](there are ~80,000 US centenarians today); on the other hand, the chances of someone becoming a
Supercentenarian is only 1:50,000. [*]
Three orders of magnitude represents a huge difference for just one decade!
Prof. Tom Perls, M.D. of The New England Centenarian Study in Boston, MA
has recently stated that the likelihood of becoming a Supercentenarian was 1 in 7 million [**],
but this calculation most likely refers to the present world population and not the population at
the time of birth.
*: These revised estimates of the rate of centenarian and Superercentenarian survivors are based on Social Security Data supplied by Donald B. Gennery, GRG Biostatistician, in which we must compare the number of survivors to the number of births during an appropriate span of time (probably ~2 years) either 100 years ago (c. 1910) or 110 years ago (c. 1900), for their respective cohorts.

What is the relative importance of Genetic Inheritance vs. Life Style?
Click for a table of 39 famous classical Greek Philosophers and Statesmen who are known to have survived past the age of 70, at least some of whom did go on to become Centenarians. Therefore, I would speculate that the density of Centenarians per capita may well have been the same in (civilized) ancient times as it is today. It's just that there has never been any good documentation for ordinary people who were not already famous for some reason or another, so all the demographics are biased in favor of wealthy or powerful individuals rather than the ordinary person. Grmek and Gourevitch speculate that during the Classical Greek Period, anyone who made it past the age of 5 years -- surviving all the common childhood illness of that day -- had a reasonable chance of living to a ripe old age. [Life expectancy at 400 B.C. was estimated to be around 30 years of age.] One demographer of ancient civilizations reported that Greek men lived to 45 years (based on a sample size of 91), while women lived to 36.2 years (based on a sample size of 55). Curiously, the gender statistics are inverted compared to today, since child-birth was a much more traumatic experience at that time than now, and it certainly skewed female statistics downward. Also recall that it was common for average citizens to take great care in their hygiene (sanitation), Mediterranean diet (fish, figs, olive oil, wine, etc.), and exercise program (sports/gymnasium), although I suspect that there was a lot more male trauma per capita than today and that biased the statistics for men downward. [Ref. Mirko Grmek and Danielle Gourevitch, Illness in Antiquity (Fayard; 1998).]
The "bottom line" is that there is no reason to believe that there couldn't have been a lot of men/women in a population of 2,500 years ago who were Centenarians, even if they weren't commonplace.

A 1995 Monograph on Exceptional Longevity: From Prehistory to the Present, Vol. 2, Edited by Bernard Jeune, M.D. and James W. Vaupel, Ph.D. in the Odense University Press Series on Population Aging is an excellent source for more details and is now available free of charge on the Internet. Click on the book cover above... The general series of Odense Monographs on Population Aging, (Max Planck Institute for Demographic Research, Rostock, Germany; 1995) is an excellent resource for the field.
Other historical sources for claims of extreme longevity can be found in the following two
1. James Easton, Human Longevity: Recording of Name, Age, Place of Residence, and Year of the Decease of 1712 Persons Who Attained a Century and Upwards from AD 66 to 1799, Comprising a Period of 1733 Years with Anecdotes of the Most Remarkable (London; UK; 1799).
Easton collected 427 anecdotes of venerable centenarians throughout human history from Roman to modern times in an uncritical manner. Most of these will not pass muster as rigorous verification methodologies were never in place in those years and they follow in the mythological traditions of high-altitude Shangri-La villages like Vilcabamba, ECUADOR, The Hunza, INDIA, and The Caucasus, RUSSIA, all of which have been discredited.
2. William J. Thoms, The Longevity of Man, Its Facts and Its Fictions (J. Murray, London; UK; 1873).
Thoms, the Deputy Librarian for The House of Lords, focused on royalty and aristocracy, whose births and deaths were recorded long before birth registration became universal in the 19th-Century. Sadly, Thoms did not find a single instance of a Peer, Duke, or Baron who lived to be a centenarian.
The Huffington Center on Aging at the Baylor College of Medicine in Houston is another interesting source for information about Centenarians.
As reported on the font cover of USA Today (August 24, 1999), The U.S. Census Bureau forecasts that the number of Americans age 100 or older will increase by more than 22 times the 1990 estimate of 37,306. In October 2001, the US Census Bureau actually reported that there were 50,454 US Centenarians (a more reasonable 35 percent increase) out of a total population of 281.4 million Americans. But by 2050, "the number of US centenarians is expected to reach 834,000 and maybe even 1 million," said Dr. Robert Butler, President of the International Longevity Center in New York City.
From present data, the number of worldwide Centenarians is around 450,000. However, if one considers only the total number of Supercentenarians (by definition, persons surviving to >= 110 years) this number falls dramatically to around 30 worldwide (See details below). To our knowledge, there are no living persons older than 120; despite the fact that there are a large number of pretenders from foreign countries, these claimants have never been rigorously validated by means of the sort of documentation that would be sufficient to prove their claim (Birth Certificates, Baptismal Certificates, Marriage Certificates, and so forth). But also, recall that the art of "record keeping" was never rigorous before the age of data processing. Persons born at home in rural areas were frequently lucky if they had a family Bible to record the event let alone the correct spelling of the parents names, their ages at the time, etc.
Other highlights form the 2000 Census Report include the following:
1. The most populous state in the nation, California, has the largest number of centenarian residents, 5,341 or 0.016 percent of its population;
2. The state with the largest percentage of centenarians is South Dakota, where 0.0033 percent of residents were 100 or over. South Dakota was followed by Iowa and the District of Columbia;
3. Of the five-year age groups, the [50-to-54] category had the largest increase, up 55 percent to 17.6 million, thanks to the "Baby Boomers";
4. While women still outnumber men at older ages, the gender ratio in the [65-and-over] category increased from 67 men per 100 women in 1990 to 70 men per 100 women in 2000.
