In Asia alone, Hanoi ranks 20th out of 28 cities, behind several cities such as Bangkok (Thailand), Osaka (Japan), and above some cities such as Jakarta (Indonesia), and Mumbai (India).

The capital city is highly rated in terms of safety at public places, employment services, easy access to information from competent agencies. However,  issues relating to air quality and traffic, specifically traffic jams need to be resolved urgently.

The top 5 smartest cities in Asia include Singapore, Beijing (China), Taipei (Taiwan, China), Seoul (the Republic of Korea), and Shanghai (China).

Zurich of Switzerland topped the global list, followed by Oslo of Norway, Canberra of Australia, Geneva of Switzerland, and Singapore.

The annual ranking grades a total of 142 cities on how well they use technology in order to enhance the overall quality of citizens' life.
