Connecting the world and beyond

The ICT Development Index

​​​​​​​​​​​​​​​​​​​​​​​​​​​​
The ICT Development Index (IDI) is a composite indicator published by ITU since 2009. Its methodology has evolved over time, most recently in 2023 following a six-year hiatus in the publication of the index. The current IDI assesses the extent to which connectivity is universal and meaningful in a country – meaning that everyone can access the Internet under optimal conditions, at an affordable cost, anytime and anywhere. Recent editions of the IDI are available on ITU's website: 2023, 2024, 2025.

Recent history of the IDI


In October 2022, ITU’s Plenipotentiary Conference 2022 in Bucharest adopted a revised text of Resolution 131. This new text (Rev. Bucharest, 2022) defines, inter alia, the main features of the process for developing and adopting a new IDI methodology and of the IDI itself. 

In this context, and in line with instructs 8 to the BDT Director, the Secretariat prepared a Zero draft docu​ment​, which described a possible framework and structure for the IDI, to inform, facilitate and expedite the process. This document was posted on a discussion forum​ dedicated to the new IDI (IDI Forum), where members of the Expert Group on ICT Household Indicators (EGH) and of the Expert Group on Telecommunication/ICT Indicators (EGTI)​ were invited to share feedback on the draft methodology, comments and suggestions. More than 200 members signed up for the IDI Forum and almost 100 comments were posted. A document with a compilation of all the comments received on the content and the respective responses from the ITU Secretariat was produced and posted on the IDI Forum. 

The Zero draft document was revised in light of the comments received to produce a Version 1 document, which also contained additional proposals related to the treatment of outliers, aggregation and weighting. A compilation of all the comments received and the Secretariat’s responses to each of them were appended as Annex 4 to the Version 1 document. 

In Circular BDT/DKH/IDA/009​, Member States were invited to comment on the Version 1 document, as per instructs the Director of the Telecommunication Development Bureau 7 of Resolution 131. The period of consultation for Member States ran from 21 April 2023 to 19 May 2023. Fourteen Member States submitted a total of 71 comments. 

Based on these comments, the Secretariat updated the Version 1 document and produced a Version 2 document. Annex 4 of that document featured a compilation of the comments submitted by Member States on the Version 1 document and the Secretariat’s responses to each of them. 

Following these consultations, the ITU Secretariat identified outstanding issues, which were presented in the Version 2 document. These outstanding issues were discussed at the virtual joint meeting of EGTI and EGH from 13 to 15 June 2023 (Circular BDT/DKH/IDA/007). 

Following the meeting, the Secretariat updated the methodology to reflect the outcomes of the meeting and produced Version 3 of the methodology. 

During its 2023 July session, ITU Council noted developments and requested that an additional meeting be organized ahead of the final consultation of Member States. Accordingly, a joint EGTI/EGH session on the IDI was held on 18-19 September 2023 (Circular BDT/DKH/IDA/013). Following the meeting, the ITU Secretariat produced Version 3.1 of the methodology, which was submitted to Member States for approval in October 2023 (Circular BDT/DKH/IDA/015​).   

In November 2023, the IDI methodology was approved by Member States​ (Circulars BDT/DKH/IDA/015 
and 
BDT/DKH/IDA/016). As stipulated in Resolution 131, the approved methodology is valid for four years. In December 2023, the 2023 edition of the IDI - based on the new methodology - was released. The 2024 edition followed in June 2024, accompanied by the launch of the ICT Development Index dashboard on the ITU DataHub. The 2025 edition​ was released in June 2025. ​The 2026 edition is expected to be released in June 2026.​

Review and revision of the IDI methodology


In parallel, in September 2023, during a joint session of the 14th Meeting of EGTI and 11th Meeting of EGH​, members agreed to establish a joint EGTI-EGH subgroup on the IDI methodology for the 2024 work period. The subgroup was tasked with reviewing the methodology and providing recommendations to inform any potential revision, should EGTI and EGH decide to update the methodology, in line with Resolution 131. 

In September 2024, the IDI subgroup presented its report for the 2024 period during a joint session of the 15th Meeting of EGTI and the 12th Meeting of EGH. EGTI and EGH members agreed to extend the mandate of the subgroup for the 2025 work period. 

In September 2025, the IDI subgroup presented its report for the 2025 period during a joint session of the 16th Meeting of EGTI and the 13th Meeting of EGH. On this occasion, EGTI and EGH members agreed to extend the mandate of the Subgroup for the 2026 work period. In addition, ahead of the expiration of the current methodology’s validity period in 2026, EGTI and EGH members also agreed to formally initiate the revision of the IDI, in accordance with Resolution 131. These decisions are reflected in​ paragraphs 18-20​ of the Summary Report of the 13th Meeting of EGH​
