World Power Index (WPI)
is defined as the numeric expression
which calculates the accumulation
of national capacities
that a State has
to exercise its power
in the international system.
The WPI is presented as
a quantitative analysis technique,
seeks help to overcome
the hermeneutic problems
caused by the subjective interpretation
of power in international relations.
Thus, the WPI contributes to
the accurate comparison
of national capacities
and the study of
 the international structure.


About the power

This website specializes in the analysis of national power in an extensive and in-depth way. Here some definitions of national power are compiled, the characteristics of national power are analyzed, and the main elements of national power are identified for their measurement. All this generates the theoretical and methodological bases for the construction of the World Power Index (WPI).

The WPI is defined as the numeric expression which calculates the accumulation of national capacities that a State possess to exercise its power in the international system. The WPI uses 18 components that are organized into 3 sub-indexes, which allow not only to analyze the national material capacities or hard power (related to globalfire power), but also the wealth of nations and their institutions quality, as well as the soft power of the countries.

The WPI is an analytical tool that allows, among other things, to define the most powerful countries (world powers), recognize the middle powers (or also called secondary powers), understand the potentialities of regional powers and observe the subregional powers. However, as it collects data for more than 170 countries, the WPI also measures the power of other minor countries that have been named small states, weak states, or even fragile state.

Thus, the WPI allows a broad and complex view of states in the international structure, in the capitalist world-economy and in the international hierarchy.

How is the index built?

Each index is built based on indicators that have been reported by national governments to international organizations. Each sub-index assesses different dimensions of power. However, the World Power Index is not only the sum of all these data but is part of a broader research agenda which has been developed for more than 10 years and seeks to be a quantitative tool for future analysis

Inmaterial capacities power

Immaterial Capacities Index

IMCI is made from six variables that are intended to reflect more broadly cultural-communicative power of a State, academic influence and cosmopolitism

semimaterial capacities power

Semi-Material C. Index

SMCI is a composite index that seeks to refer the socio-institutional power of a State from considering six fundamental variables

Material Capacities

The MCI is a composite index that seeks to reflect more broadly the economic-military power of states from considering six essential variables

It is the sum of the other 3 sub-indices (MC, SMC and IMC) resulting in the National Power. Here you can see the rise and fall of each country for years

«Power is based on national capacities, which have been configured historically. For the understanding of these, the WPI is a valuable technique, because it measures the power of nations and unveils the rise and fall of States.
