Countries with the lowest elderly populations (aged 65+) are primarily in Africa and the Middle East, with Qatar (around 1.7%) and the UAE (around 1.8%) often cited as having the smallest proportion, while African nations like Zambia, Chad, and Uganda also have very young populations. These countries contrast sharply with aging societies like Japan, where a large percentage of the population is elderly.
Qatar and the UAE have the world's lowest proportion of older adults (65+ years), at 1.7% and 1.8% respectively. African nations dominate this list, with countries such as Zambia, Chad, Uganda, and Burundi showing similarly low shares of elderly populations.
More than 55 million Americans are age 65 or older, according to the Census Bureau's 2020 population estimates. One-fourth of these older Americans live in one of three states: California, Florida, and Texas.
What Country Has the Oldest Population in the World? What country has the largest elderly population? When it comes to having the most significant aging population, Japan takes the crown. 28.2% of Japan's population is 65 years old or older, which equates to around 36.23 million people.
Monaco is the Oldest
Monaco leads this ranking with 36% of its population being over the age of 65 (translating to a median age of 57!).
On the other end of the scale, the slowest agers were found in Denmark, who were an average of 2.35 years younger than their chronological age. Next came the Netherlands and Finland.
Australia has an ageing demographic. The proportion of the Australian population aged 65 and over was 15% in 2017, a trend which is expected to continue to grow. It is estimated that by 2057 older people will account for 22% of the Australian population which translates to 8.8 million people.
Top 10 Countries with the Highest Life Expectancy
Currently, the oldest living person in Australia is Ken Weeks (born 5 October 1913), aged 112 years, 93 days, and the oldest living woman in Australia is Lorna Henstridge (born 6 June 1914), aged 111 years, 214 days.
No, no one has ever lived to be 200 years old with verified records; the oldest verified person was Jeanne Calment, who lived to 122 years and 164 days, but some scientists believe the first person to reach 200 may have already been born, given advancements in longevity research. Claims of much older ages, like Li Ching-yun (claimed 250+ years) or Peng Zu (claimed 800+ years), lack modern scientific verification.
While 59% of elderly Australians reside in capital cities, they constitute 6.3% of these urban populations. In contrast, regional areas house 41% of the elderly, where they make up a higher proportion of 8.1%.
The biggest retirement mistake is often failing to plan adequately, which includes underestimating expenses (especially healthcare), ignoring inflation's impact on purchasing power, not starting savings early enough to benefit from compound interest, and leaving retirement savings in the wrong place (like not converting super to a tax-free pension), leading to running out of money or living a constrained lifestyle. A lack of a clear budget, not understanding investment options, and neglecting lifestyle/purpose planning also rank high.
Loneliness in older people
Saudi Arabia is another one of the countries with the lowest retirement age in the world. However, it is proposed that the retirement age for both men and women should be raised to 62 years by 2024. Arab News reports that 63% of the population in the country is under 30.
The most reliable, up-to-date data about older adults who live alone comes from the U.S. Census Bureau. According to its 2023 Current Population Survey, about 28% of people 65 and older live by themselves, including slightly fewer than 6 million men and slightly more than 10 million women.
South Sudan has the highest poverty rate, with approximately 82.3% of its population living in extreme poverty, largely due to ongoing civil conflict and economic collapse.
Most deaths in Australia, like other developed countries, occur among older people (Figure 2.1). Sixty-eight per cent of deaths registered in Australia in 2023 were among people aged 75 or over (63% for males and 74% for females). The median age at death was 79.6 years for males and 84.6 years for females (Table S2.
Yes, at least one person, Jeanne Calment of France, is verified to have lived past 120, reaching the age of 122 years and 164 days (1875-1997). She remains the oldest person in history with a fully documented lifespan, making her the only person confirmed to have lived past 120.
Archeological evidence indicates that the ancestors of today's Aboriginal Australians first migrated to the continent 50,000 to 65,000 years ago.
In addition, articles comparing life expectancy of athletes compared to that of nonathletes were reviewed. Results of 13 studies describing eight different cohorts suggest that regular physical activity is associated with an increase of life expectancy by 0.4 to 6.9 years.

Deep-Sea Sponges
A deep-sea sponge can break the records of all living animals. It can live up to a thousand years. In fact, a study revealed that the oldest of the sponge samples collected lived for 11,000 years. During this time, the earth has just recovered from the Ice Age.
Most health systems recognize either 55 or 65 as advanced, given that the official age of retirement in the US is 66 years and 2 months. Older adults between the ages of 65 and 74 are often characterized as being early elderly and those who are 75 years of age and older are often referred to as being late elderly.
For example, the Australian Bureau of Statistics (ABS) groups people into population age cohorts, and differentiates between '15–64', '65 years and over' and '85 years and over'. People over 65 are generally classified as 'older' for ABS purposes.
Some signs of aging can be seen from the outside: Your hair turns gray, and wrinkles and age spots appear on your skin. Our bodies are less able to store fluid in older age, so our spinal discs shrink and lose elasticity, for instance. As a result, people get smaller as they grow older.
