1. When available, dates and timeliness requirements are only indicative and may be subject to change.
2. As often as possible, the most up-to-date version of the questionnaire has been included in this list, however, there can be slight variations from version to version. In some cases, data and metadata are collected via Web Queries, online platforms and/or via SDMX and not via a questionnaire. In these cases, a list of data series requirements or classifications are made available.
