Information Technology: Some Figures
IT sales in the United States represent 8% of GDP. For Europe it is between 5 and 6%, globally 4 to 5%. Electricity is roughly 2% in developed countries [2010 figures].
There were 300,000 professional engineers in electronics in the United States in 2006.
There were 17 millions professional software developers worldwide in 2009. 2.7 were in India, 2.3 million in the United States, 2 millions in China. The increase rate in India and China is 25% anually.
« 2.3 million developers in the United States produce in average 10 lines of code per day, which adds up to 233,750 bugs generated daily. »
Stored digital data were roughly 800 exabytes worldwide in 2009, 1.2 zettabyte in 2010, and should be around 35 zettabytes in 2020. One exabyte in one billion gigabytes (1 gigabyte = 1 billion bytes), one zettabyte is 1,000 exabytes. 1,000 zettabytes is called a yottabyte, this unit will have to be used by 2030. See http://en.wikipedia.org/wiki/Yottabyte for definitions, and http://en.wikipedia.org/wiki/Orders_of_magnitude_(data) for orders of magnitude of data.
