"This annual report presents a global and regional overview of the latest developments regarding information and communication technologies (ICTs), based on internationally comparable data and agreed methodologies. It aims to stimulate the ICT policy debate in ITU Member States by providing an objective assessment of how countries have performed in the field of ICT and by highlighting areas that need further improvement. One of the core features of the Report is the ICT Development Index (IDI). This year’s results show that nearly all of the 175 countries covered by the index improved their IDI values between 2015 and 2016. During the same period, stronger improvements have been made on ICT use than access, mainly as a result of strong growth in mobile-broadband uptake globally. This has allowed an increasing number of people, in particular from the developing world, to join the information society and benefit from the many services and applications provided through the Internet. This year, for the first time, the Report also shows countries’ rankings according to their improvement in IDI value. The results show strong improvements in performance throughout the world; a number of middleincome developing countries in particular are reaping the benefits of more liberalized and competitive ICT markets that encourage innovation and ICT uptake across all sectors. Despite these encouraging developments, we need to focus on the countries that are among the least connected in the world. Urgent action is required to address this persistent digital divide if we want to achieve the Sustainable Development Goals (SDGs) enshrined in the 2030 Agenda for Sustainable Development. For example, the Report shows that in some low-income countries, between 20 and 40 per cent of people still do not own a mobile phone and that the gender gap in mobile phone ownership is substantially higher."
