Different statistical measures create different perceptions of the digital divide

Abstract Simultaneous two-dimensional comparisons of time series data—vertically (static difference) and horizontally (Sicherl-time-distance)—for numerous ITU and Eurostat datasets show that estimates of the magnitude of digital divide can differ substantially between conventional static measures and Sicherl-time-distance, a dynamic measure of disparity. Comparing digital divide indicators with other indicators of social inequality (life expectancy, infant mortality), the analysis shows that high ICT growth rate improved well-being in developing countries and reduced some world inequalities. This methodology enables researchers, policy makers, and business managers how to draw new insights from existing data, including monitoring the attainment of targets.
