A. Summary of good practices
8.2 Compilers are advised to use the ITRS as a source for statistics of international trade in services, to review the advantages and limitations of that data source, as summarized in table 8.1, and to assess that data’s relevance and comparative importance in the context of their countries. In particular, it is good practice for compilers to explore to what extent it is possible to mitigate the limitations of that source by using such additional data sources as surveys. Some of the limitations are the undercoverage of small transactions when reporting thresholds are in place; the absence of data on services that cannot be measured or identified via the ITRS; problems with the recording of partner countries; and a lack of information on breakdowns by modes of supply.
