About 40% of world population online, 90% of offliners in developing countries.

Since 2009 on a yearly basis, they release their research findings in a report, called the MIS or Measuring Information Society Report. The report for 2014 was presented yesterday at the 12th World Telecommunication/ICT Indicators Symposium (WTIS) in Tbilisi, Georgia. 200+ pages illustrated with abundant graphs and tables is not a light read. One of the interesting numbers is the IDI or ICT Development Index, stressing a divide in global connectivity.
From the foreword by director Brahima Sanou:

Over the past year, the world witnessed continued growth in the uptake of ICT and, by end 2014, almost 3 billion people will be using the Internet, up from 2.7 billion at end 2013. .... Despite this encouraging progress, there are important digital divides that need to be addressed: 4.3 billion people are still not online, and 90 per cent of them live in the developing world.

As this report finds, ICT performance is better in countries with higher shares of the population living in urban areas, where access to ICT infrastructure, usage and skills is more favourable. Yet it is precisely in poor and rural areas where ICTs can make a particularly significant impact.

Seems like projects like Google's Project Loon have their work cut out for them.
