What makes the best city in the world? Rankings, trends and what to consider

Introduction

Debates about the best city in the world matter to residents, investors, tourists and policymakers. Annual rankings attract attention because they influence migration, tourism and investment decisions, and because they reflect changing priorities — from public health and transport to sustainability and affordability. Understanding what those rankings measure helps readers interpret headlines and decide which city might suit their needs.

How rankings work

Different indexes use different methods. Some focus on liveability and public services, others on cultural life, economy and innovation. Common criteria include healthcare, education, transport, safety, environment, cultural offerings and housing affordability. Because methodologies vary, the title of “best city in the world” can shift depending on whether a ranking emphasises quality of life, economic opportunity or cultural vibrancy.

Examples and recent trends

In recent years a number of European and Asia-Pacific cities have frequently appeared near the top of various lists, reflecting strengths in public services, sustainable transport and cultural infrastructure. At the same time, cities facing housing shortages or rising living costs may score lower on affordability even if they perform well on culture and public services. Since the COVID-19 pandemic, rankings have increasingly considered resilience — including healthcare readiness, digital connectivity and the capacity to support remote work.

Environmental measures and climate resilience are rising in importance. Cities investing in green space, active transport and emissions reductions tend to be favoured in newer assessments. Conversely, extreme weather vulnerability, congestion and housing crises are factors that can pull a city down the list despite strong cultural or economic appeal.

Conclusion

No single place will be the best city in the world for everyone. Rankings are useful snapshots that reflect particular priorities and methodologies. For readers, the key is to match a city’s strengths with personal priorities — whether that is public health, career opportunity, cultural life, affordability or climate resilience. Expect rankings to continue evolving as data improves and priorities shift; climate adaptation, affordability and digital infrastructure look set to shape future debates about which city deserves the accolade.
