The 2006 ITU World Telecommunication/ICT Development Report: Measuring ICT for Social and Economic Development has been specially prepared for the World Telecommunication Development Conference (WTDC) (Doha, Qatar 7-15 March 2006). This year’s report examines the specific issue of evaluating and measuring the impact of information and communication technologies (ICTs). ITU has long been involved in measuring the availability of telecommunication/ICT infrastructure and has more recently begun to measure the use of ICTs. Its 2003 World Telecommunication Development Report highlighted the importance of agreeing upon a harmonized and globally relevant set of Access Indicators for the Information Society and ITU’s contribution in terms of statistical information and analysis has been critical in understanding the digital divide.
