Typical measurements of inequality distribution used to describe the digital divide are the Lorenz curve and Gini coefficient. In the Lorenz curve, perfect equality of Internet usage across nations is represented by a 45-degree diagonal line, which has a Gini coefficient of zero. Perfect inequality gives a Gini coefficient of one. However, the question of whether or not the digital divide is growing or closing is difficult to answer.
The Canadian document Bridging the digital divide: An opportunity for growth for the 21st century includes examples of these measures.Figures 2.4 and 2.5 in the document show a trend of growing equality from 1997 to 2005 with the Gini coefficient decreasing. However, these graphs do not show detailed analysis of specific income groups. The progress represented is predominantly of the middle-income groups when compared to the highest income groups. The lowest income groups continue to decrease their level of equality in comparison to the high income groups. Therefore, there is still a long way to go before the digital divide will be eliminated.
