What percentage of the world's population own a computer?

Computer ownership is now at about 4-5% of the worlds population; however, with many social projects putting computers in villages in developing countries between 12-14% of the worlds population have access to a computer. Approx 3-5 % of the world's population have internet access.

To put this into context only about 25% of the world's population sleep in their own bed at night and only about 30% of the worlds population are rich enough to have a bank account!
