Manual on Statistics of International Trade in Services

B.  Set of recommended elements for phased 
implementation 
1.15. The Manual recommends a complete set of 
elements for compilers to implement that build on 
internationally agreed standards so as progressively to 
achieve comparability of published statistics on 
international trade in services.  These elements, if fully 
implemented, would represent a considerable increase in 
the detail of information available on trade in services. It 
is recognized that many countries will see the full 
implementation of the recommendations as a long-term 
goal.  The ten elements are listed below and represent a 
summary of the recommendations. 
1.16.  The first five are proposed as core  elements to 
tackle first. It is suggested that these five core elements 
should be given particular priority and that the other 
elements can be implemented incrementally thereafter. 
The five core elements would, when implemented, 
provide a basis for a common internationally comparable 
basic data set. All countries, including those that are 
beginning to develop statistics on international trade in 
services, can follow this phased approach to begin to 
structure available information in line with this new 
international standard framework.  The sequence of 
elements, as suggested, takes into account the relative 
ease that many compilers may find in their 
implementation, commencing with the easier elements.  
However, the order is intended to be quite flexible so 
that countries can meet the priority needs of their own 
institutions. 
1.17. In general, as countries implement the 
recommendations in the present Manual, it is suggested 
that they provide explanatory notes along with published 
data in order to enhance the transparency of their 
methodologies and users’ ability to compare data 
internationally. These notes should include information 
about data coverage and definitions, particularly where 
these deviate from the Manual’s recommendations. Such 
metadata provide users of the statistics with useful 
background information on such things as how the data 
are collected or estimated, where coverage is thought to 
be deficient, and where the data deviate from the 
internationally agreed standards (as described in the 
present  Manual). The provision of such explanatory 
notes along with the actual data is a practice now 
followed by many countries in a broad range of 
statistics.
