ICT Diffusion and Distribution Dataset, 1990-2007 (ICPSR 23562)

Principal Investigator(s):


This dataset covers the years 1990 through 2007 and contains two types of indicators for the global distribution of information, communication and technology (ICT) resources. The data includes gini coefficients for the distribution of Internet access within countries, and a technology diffusion index that weights the distribution of broadband subscribers, personal computers, mobile phones, Internet users, and international Internet bandwidth by economic output. The data are secondary source data, based on the analysis of primary data from 204 surveys fielded in 47 countries.
