Are all WDI series on a calendar year reporting period?
For example, annual national accounts data reported by Australia are for the fiscal year ending on June 30th. Given the rules above, the WDI figures for Australia's 2022 GDP correspond to the official data for fiscal year 2021-22, which covers the period July 2021 – June 2022. The exchange rate used to convert values from Australian dollar to US dollar is a simple average of the quarterly exchange rates reported by the IMF covering the period July 2021 – June 2022
Users may confirm the reporting period for each country by reviewing the metadata in WDI. This information can be found by selecting the desired country, series, and year, then by clicking on the ‘Metadata’ button in the upper right corner of the screen. Fiscal year information can be found in the ‘Special Notes’ section of the metadata pane.
