For the fourth consecutive year, this report presents two authoritative benchmarking tools to monitor information society developments worldwide. The ICT Development Index (IDI) ranks 155 countries’ performance with regard to information and communication technology (ICT) infrastructure and uptake. The ICT Price Basket (IPB) is a unique metric that tracks and compares the cost and affordability of ICT services in more than 160 countries globally. Both the IDI and the IPB combined are powerful measures for benchmarking and explaining differences among countries and within regions when it comes to ICT developments. This year’s edition of the report also features brand new data and analyses on revenue and investment in the ICT sector and proposes a new methodology to measure the world’s telecommunication capacity.
