Cellphone ownership in 2011: 73% of the world's population have a mobile phone

Given that mobile communications is widely acknowledged as being the main Information and Communication Technology tool in developing nations, reliable figures on the level of penetration is important. However multi-SIM card ownership, lapsed subscriptions that are still counted for a time and the growing number of machines connected to mobile networks is increasingly blurring the relevance of mobile subscription based penetration figures. For example, by the end of 2011, there were 93 countries with more mobile phone subscriptions than people. Survey data asking respondents about cellphone ownership provide a more accurate picture of mobile penetration. Recent cellphone ownership surveys have been carried out in almost 100 countries. Based on this data—representing some 90% of the world's population and mobile subscriptions—73 percent of the world's population (or 4.3 billion people) owned a mobile phone in 2011. While cellular networks have had a huge impact on access to communications, there is still some distance to go to reach ubiquity.
