The number of people aged 100 years or more (centenarians) worldwide is expected to increase significantly over the coming decades. While there were only ******* centenarians in 2000, this number is predicted to increase to over **** million by 2100. As people on the planet live longer, global life expectancy increases.

This statistic shows the number of people aged 100 and over (centenarians) in the United States from 2016 to 2060. In 2016, there were 82,000 centenarians in the United States. This figure is expected to increase to 589,000 in the year 2060.

In general, women live longer than men. As a result, the number of women aged 100 years or more worldwide is higher than that of men, and the gap is expected to continue to increase over the coming decades. It is estimated that there will be around 12.3 million female centenarians in 2100, compared to around 5.6 million males.

The study used an ethnographic methodological approach, drawing on a number of methods, including 'go-along' tours of the participant's kitchen and accompanied trips to places where food was acquired, eg supermarkets, allotments and lunch clubs. The ways that vulnerability linked to the food system might operate for different groups of older people is not straightforward but a framework for assessing different domains of vulnerability - exposure, threats, coping capacities and outcomes is proposed. Trust is thought to be an integral part of relationship building between actors in the food system and consumers are increasingly being viewed as having an active role in the trust relationship. It is unclear whether and how civil society actors within the food system undertake to build and market trust or whether the mechanisms by which trust operates or is perceived by consumers is different when the commercial sector is not involved. Assessing older people's own views on trust and their experience of different actors at the point that food is acquired is therefore important.

Like the rest of the developing world the UK is experiencing demographic change. There are currently 10.8 million people aged 65 or over in the UK and over 1.4 million are aged 85 or over. The numbers of centenarians has nearly quadrupled since 1981, from 2,600 to over 12,000 in 2010. The number of people aged 60+ is expected to be more than 20 million in the UK by 2031 and the number of individuals aged over 85 years is predicted to double in the next 20 years and nearly treble in the next 30 (Age UK 2013). A significant minority of older people have ongoing health conditions and for those aged over 85 up to two thirds has a disability or limiting long term illness. Two thirds of NHS clients are aged 65 and over (Philip 2007). Such statistics and demographic shifts highlight that addressing when, how and why older people might become vulnerable through the food that they eat should be a research priority in terms of impact on the UK food system, quality of life for individuals, better public health outcomes, reducing the burden of disease and disability not to mention the resultant economic benefits for the UK. Whilst food security and the UK food system itself are relatively secure, the potential for older people to become vulnerable could be strengthened, weakened or influenced by a number of external factors, though no research has explored such factors broadly in relation to the older population. Older people might disproportionately acquire food from different parts of the food supply chain and civil society compared with other groups of the population as they are perhaps more likely to encounter food delivery services marketed directly at them and the health professionals who care for them and through social enterprises serving food, such as 'meals on wheels' and Age UK lunch clubs. We have reviewed the datasets available via the UK Data Service and found none matches the study objectives. New data will therefore be collected and a qualitative approach used. In the first phase of the study the research team will use interviews, photography/photo-elicitation, video observation and other techniques designed to engage participants including the use of diaries with 25 households drawing on a broadly ethnographic approach to investigate the food acquisition practices and perceptions of trust of a range of household types incorporating individuals aged 60+ years. These findings will inform 4-6 focus groups with older people (Phase Two). Finally, a consensus event with stakeholders from across the UK food system will be organised to debate and critique the findings from the first two phases (Phase Three). To maximise public engagement, and ability of a lay audience to more fully participate in the study, we will develop an interactive exhibition. Members of the public, through the Public Involvement in Research group, will be a key part of the approach taken throughout the research.

As of September 2024, around 11,160 men and 83,960 women in Japan were aged 100 years and older. The total number of centenarians in that year added up to about 95,120 in the country, growing continuously over the past two decades.

There were an estimated 960 centenarians (people aged 100 and over) in Scotland in mid-2020. This is a 13% increase over mid-2019, and is the highest ever figure. This reflects the increase of births which occurred in Scotland at the end of World War One. The majority of centenarians are female. In mid-2020, there were 4 times as many female centenarians as males. There were 770 females compared to 190 males. This disparity can be explained by the difference in life expectancy for males and females. Over the past decade to mid-2020, the number of male centenarians has grown at a faster rate than female centenarians. For the 90 and over age group, numbers of males have increased by almost 70% since mid-2010, while the females have grown by just under 24%. In mid-2020, there were an estimated 43,750 people aged 90 and over in Scotland. The number of people in this age group has increased every year since mid-2010 when there were 32,440 people aged 90 and over.

In 2023, women made up about 88.5 percent of centenarians in Japan, indicating that the vast majority of people aged 100 years and older in the country were female. The share of women among centenarians peaked in the previous year at 88.6 percent.

Background: It is not understood whether long-term good health is promoted by the absence of disease risk variants, the presence of protective variants, or both. We characterized the exomes of two exceptionally healthy centenarian brothers aged 106 and 109 years who had never been diagnosed with cancer, cardiovascular disease, diabetes, Alzheimer's disease, or major pulmonary disease. Objective: The aim of this study was to gain insight into whether exceptional health and longevity are a result of carrying fewer disease-associated variants than typical individuals. Methods: We compared the number of disease-associated alleles, and the proportion of alleles predicted to be functionally damaging, between the centenarian brothers and published population data. Mitochondrial sequence reads were extracted from the exome data in order to analyze mitochondrial variants. Results: The brothers carry a similar number of common disease-associated variants and predicted damaging variants compared to reference groups. They did not carry any high-penetrance clinically actionable variants. They carry mitochondrial haplogroup T, and one brother has a single heteroplasmic variant. Conclusion: Although our small sample size does not allow for definitive conclusions, a healthy aging and longevity phenotype is not necessarily due to a decreased burden of common disease-associated variants. Instead, it may be rare ‘positive' variants that play a role in this desirable phenotype.
