Australia's high life expectancy stems from a robust healthcare system, strong public health initiatives (like gun control and mental health support), lower smoking rates, and a healthy immigrant population, leading to better outcomes in preventing cancers, heart disease, and accidents, and improving overall quality of life compared to other English-speaking nations.
According to a study by dermatologists at Monash University, Australia's closer location to the equator, higher elevation, and clearer skies presents higher levels of UV radiation exposure. Researchers state that the high UV levels put Australians at a higher risk of photoaging.
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.
Top 10 Countries with the Highest Life Expectancy
Despite healthcare spending increases, chronic conditions present a key challenge for individuals, governments and society as a whole, the AIHW says. A male born in 2020–22 can expect to live on average 81.2 years, and 85.3 years for a female.
Everyone's genetics and lifestyles are vastly different, and those factors also play a role in determining a person's overall health. However, according to a Finnish study on the impact of chronic stress on life expectancy, stress can reduce a person's lifespan by about 2.8 years.
Asian Americans enjoy the longest life expectancy of any racial or ethnic group (87.3 years) in the U.S. today. Latinos enjoy the 2nd longest life expectancy of any racial or ethnic groups in the U.S. today.
The top 10 healthiest countries in the world
It's all about finding balance. The PLOS Medicine study found 3 food groups that you should consume less of to live longer. These are sugar-sweetened drinks, refined grains, and red and processed meats. Lucky for us, there's often an easy healthier swap.
In the United States in 2021, the death rate was highest among those aged 85 and over, with about 17,190.5 men and 14,914.5 women per 100,000 of the population passing away. For all ages, the death rate was at 1,118.2 per 100,000 of the population for males, and 970.8 per 100,000 of the population for women.
The most significant finding overall was that diets better aligned with current Australian Dietary Guidelines or with a Mediterranean-style diet had a 40 per cent lower risk of death compared to those with poorer diets; however, specific links between diet type and cardiovascular disease (CVD) and dementia were less ...
Certain lifestyle habits can negatively affect your physical and mental health, shortening your potential lifespan.
Compared to non-Hispanic Whites, non-Hispanic Blacks and US-born Hispanics were found to have accelerated biological aging, which is in line with other work in the HRS that has found greater biological risk among racial/ethnic minorities (Boen, 2020; Brown et al., 2017).
Australia is largely "empty" due to its harsh, arid interior (the Outback) dominated by deserts and extreme heat, making it difficult to farm and sustain large populations, leading most people to settle in the fertile, temperate coastal regions where colonization began and resources are more accessible, with over 85% of the population living along the east and southwest coasts.
You Maintain Physical Strength and Mobility
“Being able to move around easily, whether it's taking daily walks, climbing stairs, or carrying groceries, is a classic sign of healthy aging,” Dr. Badessa says. “Good strength, balance, and endurance mean you can stay independent and continue doing the activities you love.”

The Fittest Countries: Nature-Lovers Leading the Way
1/ Okinawan diet – Japan
So much so that Japan has the lowest obesity rates and third longest life expectancy of any developed country. The Okinawan diet is centred around fish, seafood, tofu, and other nutrient-rich ingredients. It's also extremely low in processed foods.
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.
American Indians in Western and Midwestern states have the shortest life expectancy as of 2021, 63.6 years. That's more than 20 years shorter than Asian Americans nationwide, who can expect to live to 84, according to a recent study by the Institute for Health Metrics and Evaluation at the University of Washington.
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.
5 Places Where People Live the Longest and Healthiest Lives
Communities with the longest average lifespans primarily eat whole plant-based foods and limit their consumption of animal products and highly processed foods. Whole or unprocessed foods mean that very little is added to or removed from the “original” food.
There are five places — called “Blue Zones” — where a disproportionately high number of residents live to 100: Ikaria, Greece; Loma Linda, California; Sardinia, Italy; Okinawa, Japan; and Nicoya, Costa Rica.
