Singapore is officially one of the smartest cities in Asia, according to the Smart City Index 2025

Singapore isn’t just a beautiful city full of scenic green spaces amidst shiny high-rise buildings. We’re big on the smarts too, as proven by the latest Smart City Index for 2025 – and there’s clearly much depth beneath our compactness.

Published by the International Society for Urban Informatics (ISUI), this Smart City Index 2025 ranking isn’t just about smartness in the traditional sense of the word, nor is it purely about technological advancements.

Rather, it makes use of global data to rank 73 cities based on six core dimensions: citizens, environment, social landscape, economy, infrastructure, and governance. Each dimension then further considers multiple objectives for a holistic view of a city’s given level of ‘smartness’. For example, under ‘citizens’, there’s education, lifelong learning, and health; while under ‘social landscape’, there are factors like healthcare, housing, safety, and mobility, among others.

They call it the Swiss standard of living for a reason, and Stockholm takes the trophy – followed by Washington, D.C. and Barcelona, Spain in the second and third spots.

As to where Singapore stands on this list? Globally, we rank 21st – and there’s good reason for us to be proud as we’re part of the top five smartest cities within Asia. Tokyo stands strong as the number one smartest city in Asia (#5 globally), while other neighbouring cities in the region that beat us in ranking include Hong Kong (#8) and Seoul (#13).
