In Asia, Viet Nam was ranked 6th, behind Singapore, Chinese Taipei, Japan, South Korea and the Philippines.

The report, released on March 20, surveyed people from 143 countries and territories, ranking their happiness based on a three-year average of each population's assessment of their quality of life, from 2021 to 2023.

Interdisciplinary experts from the fields of economics, psychology, sociology and beyond then explained the variations across countries and over time using six factors: GDP, life expectancy, having someone to count on, a sense of freedom, generosity and perceptions of corruption.

The data gathered for the factors came from organizations like the World Bank, the World Health Organization and the Gallup World Poll.

"These factors help to explain the differences across nations, while the rankings themselves are based only on the answers people give when asked to rate their own lives," according to a statement by the World Happiness Report.

Viet Nam's population was estimated at 100.3 million in 2023, ranking third in Southeast Asia after Indonesia and the Philippines and 15th in the world, reported the General Statistics Office.

The crude death rate was estimated at approximately 5.5 per thousand inhabitants, an average level compared to the region.

The nation's under-5 mortality rate has dropped over the recent years, from 18.9 deaths per 1000 live births in 2022 to 18.2 in 2023.

The life expectancy was 73.7 in 2023, with the life expectancy for male and female at 71.1 and 76.5, respectively, only behind Singapore (83), Brunei (78) and Thailand (76)./.VGP
