Every year, global rankings attempt to answer the same question: which cities offer the best quality of life?
These indices have become influential tools for measuring urban performance, evaluating everything from infrastructure and public services to safety, environment, and economic stability. For decades, they have shaped how cities present themselves and how individuals imagine life abroad.
But for people actually making relocation decisions, “livability” is becoming harder to define through rankings alone.
As Patricia Casaburi, CEO of Global Citizen Solutions, notes:
“In the past, decisions were hugely linked to mobility or access. But now it’s more about considering where I could rebuild my life if I needed to. It’s about building optionality and resilience — not just mobility. Healthcare quality, education, political landscape, and more practical questions increasingly factor into those decisions.”
Global mobility today looks very different from the environment in which many traditional livability frameworks were developed. More than ever, relocation decisions involve balancing a wider range of priorities than traditional quality-of-life rankings alone capture.
The latest Global Intelligence Unit (GIU) briefing on the World’s Most Livable Cities for Expats reflects this change. Rather than treating livability as a static measure of urban quality, the report approaches it through the lens of relocation itself — asking not simply where life scores highly, but where people can realistically build and sustain a life over time.
And as the briefing explores, the answer extends beyond traditional quality-of-life rankings.
Changing mobility patterns are reshaping how livability is defined
Mobility patterns help explain why traditional definitions of livability are beginning to shift.
According to the GIU briefing, more than 300 million people now live outside their country of birth, with international migration reaching 304 million people in 2024.
At the same time, mobility itself has become more diverse, encompassing remote workers, entrepreneurs, retirees, internationally mobile families, and individuals seeking greater flexibility in where they live and work.
These groups rarely approach relocation in the same way.
A remote professional may prioritize affordability and connectivity. A family may focus on education and access to healthcare. A retiree may look for institutional stability and cost predictability. Entrepreneurs may evaluate access to markets alongside regulatory and mobility factors.
However, what they do share is a move away from viewing relocation solely as a lifestyle aspiration and toward a broader set of practical and long-term considerations.
While not directly assessed as part of the GIU index, these are the types of questions that shape how relocators interpret livability in practice:
- How reliable is the healthcare system?
- What education options are available?
- Will taxes align with how I live and earn?
- How difficult is administration and settlement?
- Does the city still work financially and practically over the long term?
These questions rarely dominate traditional livability rankings.
But they significantly influence relocation outcomes.
The strongest cities are not always the ones that lead in individual measures
One of the clearest findings from the GIU briefing is that modern livability appears to reward balance rather than excellence.
Across the 35 cities evaluated, no destination dominated every category. Cities that performed strongest overall were not necessarily those with the best healthcare, lowest costs, cleanest air, or highest safety scores individually.
Instead, the highest-performing destinations tended to score consistently across multiple dimensions while avoiding significant weaknesses.
That distinction matters because relocation decisions are rarely made on a single variable.
A city with lower living costs may require trade-offs elsewhere. Highly social and welcoming destinations may not offer the same institutional infrastructure. Cities with exceptional healthcare systems may come with significantly higher operating costs.
The briefing identifies several examples of these trade-offs.
Affordable destinations did not consistently deliver the strongest healthcare outcomes. Cities scoring highly on expat friendliness did not necessarily rank highest overall. Meanwhile, cities that led in individual indicators often failed to secure top positions in the composite ranking.
As Liana Simonyan, Research Associate of the Global Intelligence Unit, explains:
“One of the GIU’s most significant findings is that the top-ranked cities on structural indicators are often the hardest to settle into socially. Cities offering the strongest healthcare, safety, and institutional infrastructure are frequently the most demanding to break into socially, a finding with important implications for relocators.”
The implication is straightforward: livability appears to be becoming less about finding the highest-performing city and more about finding the city with the fewest compromises.
Relocation decisions extend beyond traditional quality-of-life measures
The patterns emerging from the GIU briefing become particularly visible when relocation decisions move from comparison into planning.
Joe Rice, Head of Citizenship Programs at Global Citizen Solutions, says relocation decisions often evolve as clients move from broad ambitions into practical planning.
“People often think they need one solution, but once you understand how they actually want to live, the answer is often different.”
What initially appears to be a conversation about geography or mobility often evolves into broader discussions around long-term planning and the conditions that support it.
Beyond the factors directly assessed in the GIU index, considerations such as education, healthcare, and taxation increasingly shape how individuals evaluate long-term relocation decisions.
Education becomes part of evaluating continuity and long-term opportunity.
Healthcare functions as a measure of resilience and predictability rather than emergency planning.
Tax becomes part of assessing sustainability and planning certainty rather than simply reducing cost.
Together, these considerations show a broader shift in how relocation decisions are being made.
As Joe notes:
“Risk isn’t just money. There’s health, safety, education, and quality of life.”
Relocation decisions reflect a broader understanding of the conditions that support long-term quality of life.
Rankings still matter — but more as decision tools rather than conclusions
This does not mean traditional livability rankings have become irrelevant.
Safety, infrastructure, environmental quality, affordability, and accessibility remain essential components of relocation decisions.
What appears to be changing is how those indicators are interpreted.
The GIU briefing suggests that livability functions as a framework for fit rather than objective superiority.
Different relocation profiles produce different priorities — and cities create value in different ways depending on those priorities.
For some, affordability and integration may outweigh institutional strength.
For others, healthcare, education, and predictability may carry greater weight than cost.
The most livable city is no longer necessarily the one that performs best in isolation. It is the city that provides the right balance of conditions for the life someone is trying to build.
As global mobility becomes more intentional and more personalized, the definition of livability may continue to evolve with it. Not away from quality of life, but toward a broader question:
Where works best for you?
