The eleven member states, including Timor-Leste, which joined on October 26, 2025. Today’s membership is used for every year shown, so totals for earlier years are not totals of the members at that time. Source: ASEAN: about ASEAN. Membership checked October 10, 2026.

Totals and shares on this page are SOTW sums of country figures, not official aggregates, and each figure keeps its own year. IMF projection: a forecast from the IMF World Economic Outlook, revised at each release, not a measured value.

About these figures

IMF figures for the current year and later are projections from the World Economic Outlook and change with each edition; earlier IMF years can still be estimates. Some economies report on a fiscal year rather than a calendar year, and the source data do not record each country-specific fiscal-year mapping, so the same year label may not cover the same twelve months everywhere.

Nominal GDP is converted from the IMF's billions of US dollars to US dollars at market exchange rates; it is not output at purchasing power parity. GDP per person is already in dollars per person.

World Bank population figures are midyear estimates. Population growth is the exponential change between successive midyear populations, expressed as an annual percentage. A population count and a growth rate can refer to different years.

Totals include only the economies and years described with them. Missing readings are not zero. Growth, inflation, unemployment and debt percentages are not added up or averaged into a world or group rate, and GDP per person is not calculated by dividing totals from different years or coverage.

These are the figures currently stored, not a single fixed edition. Open a value for its series and history.

How big is the ASEAN economy compared with the world?

The ASEAN members’ combined nominal GDP of $4.51 trillion for 2026 (IMF projection) equals 3.6% of the $126.88 trillion total for the 189 economies SOTW covers for that year. Both totals are SOTW sums of IMF country figures, not official aggregates, and economies without a figure for that year are left out of both.

Can country growth rates be averaged to obtain a world or group growth rate?

No. An unweighted average gives each country equal influence regardless of its size. Published aggregate growth requires the provider’s weighting and aggregation method. This page reports country rates with their individual reference years.
