Transition of Global ICT Diffusion by region and medium

Long-term data observation for 215 countries and regions

Abstract

The purpose of this study is to provide a quantitative and comprehensive understanding of global ICT diffusion trends. For 215 countries and regions from 1990 to 2020, we conducted the relationship between income and education levels and ICT diffusion, the Gini coefficient measurements, and the amount of ICT equipment. As a result, while the decline in the Gini coefficient for cell phone has slowed since 2010, the Gini coefficient for the Internet has continue to decline at an almost constant pace until 2020. In addition, the pace of cell phone growth has slowed, and cell phone penetration appears to be reaching maturity in many countries.
