The Little Data Book on Information and Communication Technology 2015 Summary

Core Content

The Little Data Book on Information and Communication Technology 2015 provides a comprehensive overview of the global progress in ICT development from 2005 to 2014. It includes comparable statistics across various indicators for 214 economies, focusing on economic and social context, sector structure, efficiency and capacity, and performance in terms of access, usage, quality, affordability, trade, and applications. The data is presented in regional and income group tables, allowing for cross-regional comparisons.

Main Points

• ICT Growth: Since the late 1990s, access to ICTs has grown rapidly, driven by wireless technologies and market liberalization. In 2015, there were over 7 billion mobile-cellular subscriptions globally, with 3.2 billion people using the Internet.
• Economic and Social Impact: ICTs have significant economic benefits, including increased productivity, lower costs, new opportunities, job creation, and enhanced trade. They also improve services in health and education and contribute to social cohesion.
• Data Scope: The book covers data for 2005 and 2014, with some entries for the most recent year. It includes indicators such as population, urbanization, GNI per capita, GDP growth, literacy rates, and school enrollment.
• Access and Usage: There has been substantial growth in mobile subscriptions and Internet access, with notable increases in the number of households with computers and Internet access. However, usage metrics such as international voice traffic and domestic mobile traffic show varied trends.
• Quality and Affordability: Mobile-cellular coverage has improved significantly, and Internet bandwidth has increased. Affordability metrics, such as sub-basket costs, are provided for fixed-line, mobile, and broadband subscriptions.
