The 2030 Agenda for Sustainable Development, which was adopted by the United Nations in September 2015, recognizes the immense potential of ICTs to "accelerate human progress" and specifically refers to the need to "significantly increase access to information and communications technology and strive to provide universal and affordable access to the Internet." ( United Nations, 2015a). This chapter presents the latest ICT price data collected by ITU and analyses the price and affordability of three key ICT services (mobile-cellular, fixed-broadband and mobile-broadband), benchmarking countries and regions, and highlighting key trends over time. Fixed-broadband services recorded the largest price drop of all ICT services analysed in this chapter from 2008 to 2017, while fixed-broadband subscriptions per 100 inhabitants doubled worldwide (Chart 4.1).
