That review has been informed by a range of inputs from ITU and other UN agencies, including a comprehensive assessment of progress towards the WSIS targets, the Final WSIS Targets Review, published by the Partnership on Measuring ICT for Development in 2014 (Partnership on Measuring ICT for Development, 2014a). The ICT Development Index (IDI), which combines data concerning ICT access, use and skills in an overview assessment of national ICT ecosystems, is reported on in Chapters 2 and 3, while the ICT Price Basket (IPB), concerned with affordability, is the subject of Chapter 4. The remainder of the present section briefly summarizes information society developments since WSIS and during the past year. The second section introduces the Connect 2020 Agenda.
