The Digital Opportunity Index is an e-index based on internationally-agreed ICT indicators. This makes it a valuable tool for benchmarking the most important indicators for measuring the Information Society. The DOI is a standard tool that governments, operators, development agencies, researchers and others can use to measure the digital divide and compare ICT performance within and across countries. The Digital Opportunity Index (DOI) is based on 11 ICT indicators, grouped in 3 clusters: opportunity, infrastructure and utilization. The DOI has been compiled for 181 economies for a period of three years from 2004-2006. An even longer time series for 62 leading economies for the period 2000-2006 is also available.
