The Lowy Institute Asia Power Index

Asia’s economic transformation is reshaping the global distribution of power, with profound implications for war and peace in the twenty-first century.

About the Lowy Institute Asia Power Index

The Asia Power Index, launched by the Lowy Institute in 2018, measures resources and influence to rank the relative power of states in Asia. The project maps out the existing distribution of power as it stands today, and tracks shifts in the balance of power over time.

The Index ranks 26 countries and territories in terms of their capacity to shape their external environment — its scope reaching as far west as Pakistan, as far north as Russia, and as far into the Pacific as Australia, New Zealand and the United States.

The 2023 edition, which covers five years of data, is the most comprehensive assessment of the changing distribution of power in Asia so far. Among other measures, it tracks the unfolding impact of Covid-19 — and diverging national responses to the pandemic — on Asia’s geopolitics.

The project evaluates international power in Asia through 133 indicators across eight thematic measures: military capability and defence networks, economic capability and relationships, diplomatic and cultural influence, as well as resilience and future resources. More than half the data points draw from original Lowy Institute research, while the rest are aggregated from hundreds of publicly available national and international sources.

This year, the Index includes three new indicators that track the diplomatic engagement of all Index countries, enabling additional comparisons of the patterns of diplomatic and defence engagement across Asia.

Dynamic features — including an interactive map, weightings calculator, network analysis, country comparisons, and drill-down explorations of each indicator across multiple years — establish the Lowy Institute Asia Power Index as an indispensable research tool for the study of power in Asia.
