Tables 1, 2 and 3 show the correspondence between the indicators covered in this guide and sub-component issues of the MDIs. As explained above, several areas are not covered by the current questionnaires. Many of the issues that are not covered can be treated by additional qualitative assessments and via studies such as those currently conducted at the country level with the assistance of UNESCO. The UIS indicators can be seen as proxies in several cases, in that they do not all measure directly the issue of interest, but coupled with other aspects (qualitative), they have definite relevance.
