What are the most powerful countries in the world?

This article focuses on the most powerful countries in the world, depending on a range of criteria which create different sets of rankings.

A country may be powerful simply because of its military might, while another may have a strong economy but relatively smaller defense budgets, as is the case with Germany and Japan.

For much of the 20th century and since the year 2000, the U.K. has been able to punch above its belt because of its geographical position, its language and powerful allies.

Although China’s military spending is not that different to the UK’s or France’s, its army has more than ten million more soldiers.

There are a number of different factors that determine what the most powerful countries are, including: military power, economic power, foreign affairs status, and energy security.

This information article provides a ranking of the most powerful countries based on The National Power Index (NPI) and a ranking of the most powerful countries based on comprehensive national power.

National Power Index

The most powerful countries can be quantified using The National Power Index, which combines the weighted factors of GDP, population, technology, and defense spending. Click here for the full detailed methodology on how the most powerful countries in the world is calculated.

According to Nation Ranking:

“The National Power Index (NPI) is an attempt to quantify a nation’s power, i.e. its capacity to influence events and outcomes across the globe. It is a composite of five sub-indexes, each describing one of the elements which objectively contribute to a nation’s power: economy, military, diplomacy, technology and popularity.”
