The ICT Development Index - Background

Page Content 10
​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​The ICT Development Index (IDI) is a composite indicator that until 2017 combined 11 indicators into a composite score. It is used to monitor and compare developments in information and communication technology (ICT) between countries and over time. The IDI was published from 2009 to 2017. 

The 2017 edition of the IDI was published in the Measuring the Information Society Report 2017  and the results are still accessible via the IDI visualisation tool . Those results, however, are largely outdated, considering the rapid evolution of the ICT landscape. Users should therefore exert extreme caution when using the results and drawing conclusions about the current state of digital development of a country. 

In March 2017, an extraordinary meeting of the Expert Group on ICT Household Indicators (EGH) and Expert Group on Telecommunication/ICT Indicators (EGTI) adopted a revised set of 14 indicators to be included in the IDI.  

However, following the shift from 11 to 14 indicators, countries were facing challenges in collecting and submitting quality data. For the calculation of the 2018 IDI for example, 58 per cent of the data points would have to be estimated. Furthermore, there were issues with the harmonization and quality of the data used, and the methodology applied to derive some of the newly adopted indicators. Because of these flaws it was not possible to compute a methodologically sound index that reflected the true state of ICT development. 

Since 2018, attempts either to publish the IDI in line with Plenipotentiary Conference (PP) Resolution 131 (Rev. Dubai, 2018) or to develop an entirely new index have been unsuccessful, as no consensus could be reached within the Expert Group on Telecommunication/ICT Indicators (EGTI) and the Expert Group on ICT Household Indicators (EGH). 

At a virtual consultation in June 2021, ITU’s Administrative Council –the Union’s governing body in the interval between Plenipotentiary Conferences– agreed that further discussion and any decision regarding the future of the IDI should be deferred to the next Plenipotentiary Conference. Consequently, no index was published until PP. 

During ITU’s Plenipotentiary Conference 2022 in Bucharest, Resolution 131, which  ​governs how ITU measures the information society, was revised. It was resolved that ITU should establish a valid structure and methodology for the IDI, working through EGTI/EGH, and through formal consultations with Member States that allows the publication of the IDI on an annual basis, without ranking, provided that there are sufficient valid data to cover a majority of Member States. Following these developments, work has started with the objective of resuming the publication of the IDI. More information on this can be found here.
