      "heading": "Classification of Economies",
      "content": "- The WEO divides the world into two major groups: advanced economies and emerging and developing economies.\n- The classification:\n  - \"is not based on strict criteria, economic or otherwise, and has evolved over time.\"\n  - has the objective \"to facilitate analysis by providing a reasonably meaningful method of organizing data.\"\n- Some economies remain outside the classification and therefore are not included in the analysis. Examples provided: Cuba and the Democratic People’s Republic of Korea (not IMF members, and the IMF therefore does not monitor them).\n- Last Updated: April 2025"

    {
      "heading": "Aggregation methods — general rules",
      "content": "- Composite data for country groups in the WEO are either sums or weighted averages of data for individual countries.\n- Arithmetically weighted averages are used for all data for the emerging market and developing economies group—except data on inflation, for which geometric averages are used.\n- Unless noted otherwise, group composites are computed if 90 percent or more of the share of group weights is represented."

      "heading": "Aggregation conventions by data type",
      "content": "- Domestic economy (growth rates or ratios):\n  - Weighted by GDP valued at purchasing power parity as a share of total world or group GDP.\n- Inflation:\n  - For advanced economies (and subgroups): annual rates are simple percentage changes from the previous years.\n  - For world inflation and inflation in emerging market and developing economies (and subgroups): annual rates are based on logarithmic differences.\n  - Emerging market and developing economies group uses geometric averages for inflation.\n- Real GDP per capita (PPP terms):\n  - Composites are sums of individual country data after conversion to the international dollar in the years indicated.\n- Euro area:\n  - Unless noted otherwise, composites for all sectors for the euro area are corrected for reporting discrepancies in transactions within the area.\n  - Unadjusted annual GDP data are used for the euro area and for the majority of individual countries, except for Cyprus, Ireland, Portugal, and Spain, which report calendar-adjusted data.\n  - For data prior to 1999, data aggregations apply 1995 European currency unit exchange rates.\n- Fiscal data:\n  - Composites are sums of individual country data after conversion to US dollars at the average market exchange rates in the years indicated.\n- Unemployment rates and employment growth:\n  - Weighted by labor force as a share of group labor force.\n- External sector statistics:\n  - Composites are sums of individual country data after conversion to US dollars at the average market exchange rates in the years indicated for balance of payments data and at end-of-year market exchange rates for debt denominated in currencies other than US dollars.\n- Foreign trade volumes and prices:\n  - Composites of changes are arithmetic averages of percent changes for individual countries weighted by the US dollar value of exports or imports as a share of total world or group exports or imports (in the preceding year)."
