1. Monaco. One of the smallest countries in the world, Monaco also has the UN's longest estimated life expectancy of any country as of 2023.
U.S. life expectancy at birth
On average, a person living in the U.S. can expect to live to 76.1 years. Asian people have the longest average life expectancy (83.5 years) and American Indian/Alaska Natives the shortest (65.2 years).
Japan. The highest life expectancy in the world is found in Japan, where the average lifespan is 84 years. It is thought that the Japanese diet, intense physical exercise, and easy access to high-quality healthcare are important causes.
The five Blue Zones are located in: Sardinia, Italy – home to the world's longest-lived men. Okinawa, Japan – home to the world's longest-lived women.
In fact, the Melis family has been named the longest-living family in the world by Guinness World Records. The nine siblings - six girls and three boys - have a combined age of 818 years.
Life expectancy for Black people was only 70.8 years compared to 76.4 years for White people and 77.7 years for Hispanic people. It was highest for Asian people at 83.5 years and lowest for AIAN people who had a life expectancy of 65.2 years.
Japanese life expectancy
This low mortality is mainly attributable to a low rate of obesity, low consumption of red meat, and high consumption of fish and plant foods such as soybeans and tea. In Japan, the obesity rate is low (4.8% for men and 3.7% for women).
Women's life expectancy was 79 years in the U.S. in 2021, while men's was about 73, according to CDC data. The U.S. has a higher rate of avoidable deaths, which is measured as death before the age of 75, among men than any comparable country.
In Australia, the average life expectancy is 83 years (81 years for men, 85 years for women) as of 2022. In United Kingdom, that number is 82 years (80 years for men, 84 years for women) as of 2022.
The country with the highest life expectancy at birth is Spain, with an average of 83.3 years, followed by Sweden (83.1 years), Luxembourg, and Italy (both 82.7 years). The lowest lifespan is predicted in Bulgaria (71.4 years), Romania (72.8 years), and Latvia (73.1 years).
While October babies have the highest risk of disease among all birth months, they don't let that stop them from living very long lives. According to a 2011 study of over 1,500 centenarians (or people that live to be 100), babies born between September and November live the longest.
A Mediterranean diet remains one of the gold standards for living longer and more healthfully. This pattern is characterized by a high intake of fruits and vegetables; whole grains; pulses; healthful fats from nuts, olive oil, and avocado; and herbs and spices. It includes seafood a few times a week.
Response: Nearly 90% (or 6.9 years) of this gap is attributable to the fact that Asians tend to outlive whites regardless of the cause of death (age effect). The causes that contribute the most to the gap are heart disease (24%) and cancers (18%).
Japan's success in avoiding the obesity problem faced by most of the western world is down to three main factors: an appreciation of good food from cradle to grave, a lifestyle that encourages incidental exercise, and a large dollop of paternalism.
The world average age of death is a few years lower at 68.9 years for men and 73.9 years for women. Within the European Union, these are 77.7 and 83.3 years respectively. Birth rate and death rate are given in births/deaths per 1,000 inhabitants within one year. The table shows the official data from the year 2021.
The aging of the Japanese population is a result of one of the world's lowest fertility rates combined with a high life expectancy.
Asians and Pacific Islanders (hereafter Asians) outlive all other racial and ethnic groups in the United States [1-6]. Because their life expectancy at birth is 86.3 years, they outlive non-Hispanic white Americans (hereafter whites) by an average of 7.8 years (authors' calculation from 2006-2010 CDC data).
More Than Two Years Longer
In research compiled as recently as two years ago, it was determined that people living in cooler regions of the world may live an average of 2.2163 years longer than those who don't.
Your Kids Might Live Longer
As it turns out, aging sperm might produce children with longer telomeres, or tips of chromosomes, that protect DNA while being copied, which is linked to longevity for not one, but two generations of offspring.
Longer life spans tend to run in families, which suggests that shared genetics, lifestyle, or both play an important role in determining longevity. The study of longevity genes is a developing science.
Her family believes she's the oldest living Australian, at age 110 years and 8 months.
