Inflation, war, and other factors continue to be a drag on world economic growth (Economist, IMF World Economic Outlook October 2022). The outcome will be determined using IMF world GDP percent change data from the first release of the World Economic Outlook Database in 2023, which is expected in April 2023, and comparing it to the October 2022 World Economic Outlook world GDP percentage change. At the IMF website (IMF - World Economic Outlooks), choose the appropriate "World Economic Outlook Database"; then choose "Entire Dataset"; then download the "By Country Groups" file in the "Tab Delimited Values" section. On the spreadsheet, refer to the line of data, usually near the top, that has the Subject Descriptor as "Gross domestic product, constant prices" and Units as "Percent change." World GDP percentage change in constant prices for 2022 was estimated to be 3.192% according to the October 2022 report (IMF - World Economic Outlook Database October 2022). The data may also be seen using the IMF's reporting tool here: (IMF).
