In a couple of recent posts, I have mentioned the percentage of disposable income spent by Africans on mobile communication. While I have posted links to the research, I think it is worth singling out the work of Research ICT Africa.
What is in desperately short supply in Africa is rigorous, demand-side evidence of ICT usage that is comparable across borders. ResearchICTAfrica, led by Alison Gillwald, has undertaken a herculean task in carrying out extensive household and individual ICT use surveys across 17 African countries in 2007 and 2008.
If you are interested in ICTs and development in Africa you should read ICT Access and Usage in Africa (Volume One 2008, Policy Paper Two). Not to mention the treasure trove of other research on their site, which is now finally in a fit state to browse. 🙂
