Here are the top 10 smartest cities in the world — and none are in the U.S.

Smart cities in Europe and Asia are gaining ground globally while North American cities have fallen down the ranks, according to the 2024 Smart City Index released April.

Of the top 10 smart cities on the list, seven were in Europe.

This year's index was produced by the IMD World Competitiveness Center's Smart City Observatory in collaboration with the World Smart Sustainable Cities Organization (WeGO) that's based in Seoul, South Korea.

The report ranks 142 smart cities worldwide based on data analyzed by researchers, as well as survey responses of 120 residents in each city. The study captures an overview of how the infrastructure and technology available in a city impacts the city's performance and the quality of life of its inhabitants.

According to the IMD, a smart city is defined as "an urban setting that applies technology to enhance the benefits and diminish the shortcomings of urbanization for its citizens."

The cities that perform well on the list have also developed initiatives that cater to their citizens' overall quality of life.

"Such initiatives have focused on developing green spaces and broadening opportunities for cultural events and social bonding, for example," according to the report.

"In the majority of these leading cities, such efforts have been combined with innovative strategies to attract and retain talent, foster investment in a selective fashion [e.g. pro-sustainability], and tackle long standing issues regarding geographical inequalities and inclusion," the report said.

Notably, for the first time since the index's inception in 2019, there is an absence of North American cities in the top 20.
