ICT Development Index

ICT Development Index is a engineering topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand ICT Development Index rather than just read about it. In short: The ICT Development Index (IDI) is an index published by the United Nations International Telecommunication Union based on internationally agreed information and communication technologies (ICT) indicators. This makes it a valuable tool for benchmarking the most important indicators for measuring the information society.

Key takeaways

ICT Development Index belongs to engineering; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect ICT Development Index to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of ICT Development Index from memory before moving on to harder problems.

Reference excerpt

The ICT Development Index (IDI) is an index published by the United Nations International Telecommunication Union based on internationally agreed information and communication technologies (ICT) indicators. This makes it a valuable tool for benchmarking the most important indicators for measuring the information society. The IDI is a standard tool that governments, operators, development agencies, researchers and others can use to measure the digital divide and compare ICT performance within and across countries. Having the role to analyze the level of development of the information and communication technology sector (ICT), the ICT Development Index (IDI) is a composite indicator published by ITU between 2009 and 2017. It was discontinued in 2018, owing to issues of data availability and quality. In October 2022, ITU’s Plenipotentiary Conference 2022 in Bucharest adopted a revised text of Resolution 131, which defines, inter alia, the main features of the process for developing and adopting a new IDI methodology and of the IDI itself. In November 2023, the revised IDI methodology was approved by the Member States and is valid for four years. In December 2023, the 2023 edition of the IDI based on the new methodology was released. The 2024 edition of the IDI was released in June 2024.

List of countries by ICT Development Index (IDI) The following table shows the most recent values of the ICT Development Index, based on data published by International Telecommunication Union in 2024. Sorting is alphabetical by country code, according to ISO 3166-1 alpha-3.

Worked examples

Example 1 — a first encounter with ICT Development Index

Start with the simplest possible case. Write down what ICT Development Index claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In engineering, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to ICT Development Index before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about ICT Development Index ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of ICT Development Index

In research: ICT Development Index appears in engineering research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses ICT Development Index in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: ICT Development Index is common in secondary-school and first-year university syllabi. It links to neighbouring topics Economic country classifications, IT infrastructure, so understanding it makes those chapters shorter.
In everyday life: Look for ICT Development Index outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.

Frequently asked questions

What is ICT Development Index in simple terms?

Why does ICT Development Index matter?

Because it connects several engineering ideas at once: it gives you a definition you can apply, a quantity you can calculate, and a way to check whether a result is plausible.

How should I study ICT Development Index?

Read the excerpt, restate it from memory, then work through the examples and applications listed on this page. The five-step study plan above takes about twenty minutes.
