How does the DOI measure digital opportunity in the Information Society?
Composite indexes are useful in measuring complex concepts such as digital opportunity and human development as they can be used to measure different aspects and combine these measurements together in an aggregate index. The DOI measures digital opportunity in three categories of Opportunity, Infrastructure and Usage (Figure 1). Indicators in various data series are standardized on a scale of 0 to 1, by indexing relative to a reference value (data series and reference values are given in Table 1 below). These index scores on the sub-indexes are then averaged by simple average to give the overall DOI score for a country, between zero and 1 (no country has achieved the upper or lower limit scores).
