The Telecommunication Infrastructure Index is a composite weighted average index of six primary indices based on basic infrastructural indicators, which define a country’s ICT infrastructure capacity. These are: PC’s/1000 persons; Internet users/1000 persons; Telephone Lines/1000 persons; Online population; Mobile phones/1000 persons; and TV’s/1000 persons. Data for the UN Member States was taken primarily from the UN International Telecommunication Union (ITU) and the UN Statistics Division, supplemented by the World Bank. Constructing six separate indices for the indicators standardizes data across countries.
