For those of you who don't subscribe to the bimonthly print edition of Foreign Policy, you're missing a great feature: the FP Quiz. It has eight intriguing questions about how the world works.
The question I'd like to highlight this week is:
What percentage of the world's cell-phone accounts are in developing countries?
a) 25 percent b) 50 percent c) 75 percent
Answer after the jump ...
C, 75 percent.
By the start of 2009, 3 billion of the world's 4 billion cell-phone subscriptions were in developing countries, up from one-fourth of the world's total in 2000, the Economist reported in September. Connecting the poor has major benefits for the developing world. An additional 10 cell phones per 100 people in a developing country raises per capita GDP 0.8 percentage points, a recent study found. Furthermore, research is showing that mobile phones and the Internet are making agriculture more efficient in developing countries.
And even though the economy headed south last year, cell-phone demand zoomed north to 4.6 billion mobile-phone subscriptions by the end of 2009, the International Telecommunication Union (ITU) announced this week. That number is expected to reach 5 billion subscriptions sometime this year, and subscriptions that include broadband will pass the 1 billion mark at some point in 2010. The ITU even predicts that in the next five years, mobile Internet access (such as through laptops and "smart" mobile gizmos) will probably surpass Internet access from desktop computers!
