About these figures
- Combined figures are sums of the members’ own figures for one year, not official aggregates, and are shown only when every member has a figure for that year. Missing figures are not counted as zero.
- Growth, inflation and other rates are not added up or averaged into a group or continent rate, because an unweighted average gives a small economy the same weight as a large one.
- GDP is converted to US dollars at market exchange rates; GDP at purchasing power parity (PPP) adjusts for differences in price levels, so it is the better comparison of living standards and gives a different order.
- The Commonwealth Secretariat does not publish the year each member joined on its member list, so no join year is shown.
- IMF figures for the current year are projections from the World Economic Outlook, revised at each release, not measured values.
