We live in a world of data ...

... but that is not new. We have always lived in a world full of data, the difference between yesterday and today is our capabilities to pack and process the information that has been always available. 


  • How much data exists in the digital universe as of 2012: 2.7 zetabytes*
  • Increase in the quantity of Internet data from 2005 to 2012: +1,696%
  • Percent of the world’s data created in the last two years: 90
  • Number of exabytes (=1 billion gigabytes) created every day in 2012: 2.5; that number doubles every month
  • Percent of the digital universe in 2005 created by the U.S. and western Europe vs. emerging markets: 48 vs. 20
  • Percent of the digital universe in 2012 created by emerging markets: 36
  • Percent of the digital universe in 2020 predicted to be created by China alone: 21
  • How much information in the digital universe is created and consumed by consumers (video, social media, photos, etc.) in 2012: 68%
  • Percent of which enterprises have liability or responsibility for (copyright, privacy, compliance with regulations, etc.): 80
  • Amount included in the Obama Administration’s 2-12 Big Data initiative: over $200 million
  • Amount the Department of Defense is investing annually on Big Data projects as of 2012: over $250 million
  • Data created per day in 2012: 2.5 quintillion bytes
  • How many terabytes* of data collected by the U.S. Library of Congress as of April 2011: 235
  • How many terabytes of data collected by Walmart per hour as of 2012: 2,560, or 2.5 petabytes*
  • Projected growth in global data generated per year, as of 2011: 40%
  • Number of IT jobs created globally by 2015 to support big data: 4.4 million (1.9 million in the U.S.)
  • Potential shortage of data scientists in the U.S. alone predicted for 2018: 140,000-190,000, in addition to 1.5 million managers and analysts with the know-how to use the analysis of big data to make effective decisions
  • Time needed to sequence the complete human genome (analyzing 3 billion base pairs) in 2003: ten years
  • Time needed in 2013: one week
  • The world’s annual effective capacity to exchange information through telecommunication networks in 1986, 2007, and (predicted) 2013: 281 petabytes, 65 exabytes, 667 exabytes
  • Projected amount of digital information created annually that will either live in or pass through the cloud: 1/3
  • Increase in data collection volume year-over-year in 2012: 400%
  • Increase in number of individual data collectors from 2011 to 2012: nearly double (over 300 data collection parties in 2012)
*1 zetabyte = 1 billion terabytes | 1 petabyte = 1,000 terabytes | 1 terabyte = 1,000 gigabytes | 1 gigabyte = 1 billion bytes



Whichever number in the list above that you pay attention is impressive. Choose your favorite one and think about it. My favourite number is the percentage of world´s data created in the last 2 years: 90%.

Thoughts about that number. Firstly, it is not totally true, we are talking of the percentage of information in our hands that was created in the last two years. We can be sure that we have lost a lot of data that our ascendants created. Nevertheless, it is true that soon almost all the knowledge that we will be able to analyze and study in our live will have been created during our existence. What will be the consequence for our society? Will we lost the wisdom of our ancestors? Will we repeat again and again the same errors that our ancestors made before?
