Table 2 Eligibility criteria for the three sections of the ECHI shortlist, also used for section transfers [20]

Eligibility criteria for the implementation section (currently 67 indicators)

 There is consensus on the indicator definition and calculation, and data are adequately available in international databases -- > the indicator can be used to support policy making, it is ready for implementation at (inter)national level

Eligibility criteria for the work-in-progress section (currently 14 indicators)

 There is consensus on the indicator definition and calculation, or considerable developmental work has already been carried out (i.e. consensus can be reached within a limited amount of time), but the indicator is not yet incorporated in regular international data collections. There is an overview of national data availability and data are available in a reasonable number of countries -- > technically, the indicator is (nearly) ready for incorporation in regular international data collections, but there may not yet be concrete plans for this.

Eligibility for the development section (currently 13 indicators)

 This section contains those indicator topics that are not ready yet for incorporation in international regular data collections (and thus for implementation) due to considerable methodological and/or data availability problems.
