The rapid economic development along with the higher scores in the fields of recreational and art activities, private education, and road infrastructure were the main factors that helped the Vietnamese cities increase their places in the ranking.
Those that score the best tend to be mid-sized cities in wealthier countries, according to the survey.
The survey of liveable cities is conducted annually based on various criteria such as stability, health care, culture and environment, education, and infrastructure.
The ten most liveable cities are Vienna (Austria), Melbourne (Australia), Osaka (Japan), Calgary (Canada), Sydney (Australia), Vancouver (Canada), Toronto (Canada), Tokyo (Japan), Copenhagen (Denmark) and Adelaide (Australia).
