People all over the world are living longer due to improvements in lifestyle standards, medications, and better healthcare. The average life expectancy in almost every country has increased over the last several decades.
Economics plays a critical role. On average, people in high-income countries live 23 years longer than those in low-income nations, according to the World Health Organization.
But climate, diet and life choices are other factors significantly contributing to how many birthdays locals get to celebrate. The secrets to longer lives also include healthy and happy social relationships where the elderly feel appreciated.
There are five cities where people live measurably longer lives, popularly known as the Blue Zones. From Ikaria, Greece to Nicoya and Costa Rica, years of investigative research has helped to identify the daily habits and diets of people who are living to an age of 100 at a rate 10 times greater than in the U.S. But these five locales don’t make up the entire list.
The following ranking, in an ascending order, is based on 2016 CIA estimates. Life expectancy at birth compares the average number of years to be lived by a group of people born in the same year. It is also a measure of overall quality of life in a country.
