The E-Government Development Index (EGDI) is a composite indicator which is used to measure the readiness and capacity of national institutions to use information and communications technologies (ICTs) to deliver public services. It is the product of a survey—the only global report that assesses the e-government development status of all United Nations Member States. It is based on the weighted average of three normalized indices: 1) telecommunications infrastructure index (TII), 2) human capital index (HCI), and 3) online service index (OSI).
