How it works
The index combines five features of a country into one score. The score is meant to describe how well its underlying structure can handle stress, not how powerful it appears today. The sections below explain each part of the calculation.
Modernization Index (MI)
A score from 0 to 1 that averages five pillars. Each pillar contributes 20 percent of the published score.
Why it matters. It provides a quick comparison across countries while keeping the five underlying pillar scores available for review.
For example. Switzerland scores about 0.87, while countries with much weaker structural conditions may score below 0.30.
Score band
Five colored ranges of the MI score: Band 1 is 0.80 or higher, Band 2 is 0.60 to 0.79, Band 3 is 0.40 to 0.59, Band 4 is 0.20 to 0.39, and Band 5 is below 0.20.
Why it matters. Score bands make the map and lists easy to scan without implying a separate model or evidence level.
The five pillars
These are the five traits we measure for every country. Each is scored 0 to 1 from citable public data, then combined with equal 20 percent weights into the MI v3.3 score.
Institutions
How well courts, public agencies, anti-corruption rules, and political accountability work in practice.
Why it matters. Strong institutions give a country established ways to respond to a crisis and resolve disputes.
For example. During a crisis, functioning courts and elections can provide an orderly way to settle disputes.
Economic Complexity
A measure of the range and sophistication of what a country produces and exports.
Why it matters. A diverse economy has more ways to adapt when one sector fails. An economy that depends on one product has fewer alternatives.
For example. A country that depends heavily on oil is more exposed to oil-price changes than one that exports machinery, chemicals, and software.
Human Capital
How educated and healthy the population is.
Why it matters. Education and health affect a country's ability to adapt, provide services, and recover after disruption. They usually change slowly.
For example. Post-war recoveries are far faster where the workforce is already educated.
Economic Structure
How wealthy the country is, in income per person.
Why it matters. Higher income can provide reserves and policy options. Its effect depends partly on whether institutions are strong enough to manage those resources.
For example. An oil-producing country can have high income even when its institutions remain weak.
Stability & Resilience
A read on present political stability and the absence of acute fragility.
Why it matters. It captures whether the other pillars are currently holding together or already under visible strain.
The shape matters too
Two countries can share the same score and be built very differently. So we look at two relationships that a single number hides.
Durability gap
The relationship between how wealthy a country is and how strong its institutions are.
Why it matters. The historical cases suggest that high income is less durable when institutions remain comparatively weak.
For example. Two countries can have similar incomes but different institutional strength, which can lead to different readings of durability.
Structural shape
How even or uneven a country's five pillar scores are.
Why it matters. A very weak pillar can matter even when the overall average looks healthy. The spread shows information that the combined score can hide.
External security context
The five pillars describe conditions inside a country. They do not capture external threats or the protection offered by allies. A separate layer records that context as it is reviewed country by country.
Exposure
The raw external threat a country sits under, independent of how it is built inside.
Why it matters. Internal strength cannot remove every external threat, so exposure is recorded separately.
Protection
Whether a credible ally or alliance is expected to help defend the country.
Why it matters. In the historical cases, outside protection changed the outcomes of some countries facing similar threats.
For example. After Iraq invaded Kuwait in 1990, an international coalition restored the Kuwaiti government.
Response
The ability to respond after an external shock through internal capacity or outside help.
Why it matters. Exposure measures the external threat. Response measures the capacity available after the threat becomes real.
The score is a formula
The core score is a fixed calculation over published inputs. The same inputs, version, and settings give the same answer. Some additional checks and historical context are reviewed by people. Those parts are labeled separately and never silently folded into the score.
