This index brings together, in one comparable framework, the residence programs that allow people to retire or live abroad on passive income. This section explains what the index measures, how it is built, and how to read it.
Choosing where to spend a long retirement is one of the most consequential decisions a globally mobile individual can make — yet the information needed to compare countries is scattered across immigration statutes, tax codes and a dozen unrelated data sources. We built this index to close that gap: to compare, on a like-for-like basis, the residence routes designed for people who will support themselves from pensions, savings and investment income rather than local employment.
It is written for that reader — the internationally mobile retiree or financially independent individual weighing their options — and for the advisers, journalists and policymakers who serve them. It takes a deliberately holistic view: the best destination is rarely the one with the lowest tax or the fastest passport alone, but the one that balances lifestyle, financial treatment, ease of process and long-term security.
The 2026 edition covers 46 jurisdictions across Europe, the Americas, Asia-Pacific, the Middle East and Africa. Each is represented by a single flagship program — the residence route most clearly aimed at retirees or the financially independent, such as Portugal’s D7 Visa or Spain’s Non-Lucrative Visa. Judging each country on one representative route, rather than its most flattering one, keeps the comparison honest and consistent.
Every program is assessed across five pillars, each capturing a different dimension of the decision. The pillars are weighted to reflect what matters most to a typical mobile retiree: quality of life carries the greatest weight, because it shapes daily experience more than any single financial variable, followed by mobility and citizenship, and then the financial and procedural dimensions.
Figure 1. How the five pillars are weighted in the overall score.
Within each pillar, the index draws on a focused set of factors — a mix of respected independent benchmarks and primary legal and tax research. Figure 2 shows the full picture at a glance.

The index combines two kinds of evidence. For the lifestyle and mobility measures it draws on established, independent benchmarks — among them the Global Peace Index for safety and the Environmental Performance Index for environmental quality, alongside recognized measures of living standards, English proficiency and passport strength. For the program-specific facts — income thresholds, processing times, tax treatment, citizenship timelines and family rules — it relies on primary legal and governmental sources and specialist immigration research, verified for the current year.
Anchoring the subjective dimensions in named, third-party benchmarks keeps the index grounded in evidence rather than opinion.
The scoring is designed to be transparent in principle and consistent in application. Every measure, whatever its original units, is placed on a common 0–100 scale, so that safety, tax rates, processing times and costs can be compared on equal terms. Each pillar combines its factors into a pillar score; the five pillar scores are then combined, according to the pillar weights, into a single overall score. Countries are ranked on that overall score, and each pillar is also ranked in its own right.

Immigration and tax rules change constantly, and an index is only as good as its currency. Each edition is refreshed and re-verified against primary sources and updated to reflect legal change. The 2026 edition, for example, incorporates Portugal’s reform of its nationality law, which extended the naturalization residence requirement from five years to ten (seven for EU and Portuguese-speaking-country nationals) — a change that materially affects how that country’s route compares.
A few principles help in reading the results well:
- Scores are relative. Each score reflects a country’s standing within this group of 46 programs, not an absolute rating — it is a way of comparing, not a grade.
- Read the top as tiers. The leading programs are separated by very fine margins, so the top of the table is best understood as a cluster of strong options rather than a strict order of merit.
- The weighting reflects a point of view. The pillars are weighted for a typical mobile retiree; a reader who cares only about tax, or only about a fast second passport, would weigh them differently.
- It is a starting point, not personal advice. The right choice for any individual depends on nationality, income, family and personal circumstances that no general index can capture. The index is designed to narrow the field, not to make the decision.
A detailed technical methodology — covering the complete indicator set, the weighting applied within each pillar, the scoring approach and our data-quality procedures — is maintained by our research team and available to journalists and researchers on request.
