To account for these discrepancies, the ITU (International Technology Union) has introduced the ICT (Information and Communication Technology) development Index (IDI). In spite of the divide, but still at a slower pace, developing countries (and specially emerging countries) are experiencing increased internet access, deeper penetration of telecommunications infrastructure (mobile and fixed lines, fiber optics, etc) and decreasing prices for computers and other technologies.
Taking into account this view, (GIZ, 2010) provides us with data published by (Qiang, 2009) on behalf of the World Bank relating the level of increase in the diffusion of selected technologies to the corresponding increase in GDP (Figure 1).
The figure clearly shows that 1) enhanced ICT infrastructure can be positively related to economic growth and 2) these technologies have a deeper impact for low and income as compared to high-income countries.
The difference of the relative ICT impact for the two different groups of countries lies on the fact that the productivity gains, better functioning of the markets, reduced transaction costs made possible by these technologies are more noticeable where there is much room for improvement, the case for developing countries (Qiang, 2009).
ICT also has macroeconomic impacts related to the level of employment and job creation, attraction of FDI (Foreign Direct investment), tax revenue, and improved export gains.
 The interested reader can refer to (GIZ, 2010) for detailed statistics on how ICT impacts these factors.
 IDI is composed of 11 indicators, related to ICT access, use and skills, such as households with a computer the number of Internet users and literacy levels.
