Measuring the Information Society Report

Since 2009, the International Telecommunication Union (ITU) has been publishing its annual ICT Development Index (IDI), which benchmarks countries’ performance with regard to ICT infrastructure, use and skills. The JRC analysis, conducted at ITU’s invitation, suggests that the conceptualized three-level structure of the 2015 IDI is statistically sound in terms of coherence and balance, with the overall index as well as the three sub-indices – on ICT access, use and skills – being driven by all the underlying components. The IDI has a very high statistical reliability of 0.96 and captures the single latent phenomenon underlying the three main dimensions of the IDI conceptual framework.
