2011 National Power Index

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.

About the NPI

The NPI reflects the current situation, and does not attempt any predictions of the future. As such, it does not take into account dynamic factors such as growth, and only represents their visible results. The NPI also does not consider factors of debatable relevance, in particular factors which are only deemed relevant to national power by certain ideologies, and does not use self-reported data.

All indexes are based on the latest numbers available on 1 January 2011.
