Measure power.
Understand nations.
See national capability, the social structure beneath it, and the evidence behind the change.
How the Power and structural frameworks fit together
Current power. System quality. Direction of travel.
The headline system separates present capability, structural quality, durability, vulnerability and direction. The public site explains what each lens means without publishing the proprietary scoring engine.
Overall Rank
The primary national-power ranking. It integrates current capability with the quality and durability of the system supporting it, while keeping risk visible.
Present national capability across the principal hard, economic and strategic domains.
Headline power after structural constraints and vulnerability are taken into account.
The quality of the system supporting national capability.
Whether national conditions are strengthening, flat or weakening.
A forward view of relative national capability.
How current position compares with direction of travel.
Eight capability families. One strategic picture.
PolisMetric looks across the principal domains through which states project, finance, sustain and renew national capability. Production construction remains proprietary.
What headline power can miss.
IDG is the structural diagnostic layer beneath the Power Index: Identity, Drive and Grit provide context on cohesion, dynamism and resilience without being mistaken for national power itself.
Structural Strength across major countries
A high current level and a positive direction are different things. The long-run series makes both visible.
IDG Structural Strength

Structural movers
Identity. Drive. Grit.
Three distinct dimensions help explain the social foundations that conventional economic and military measures can miss.
Level is not momentum
A strong country can be deteriorating, while a weak country can be improving. PolisMetric separates current position from direction.
