According to researchers at the University of Southern California (Washington Post, 2011), the world's storage capacity for digital data increased from 0.2 billion gigabytes in 1986 to 276 billion gigabytes by 2007 (at the same time analogue storage capacity increased from 2.6 to 18.9 billion gigabytes). This huge growth is often seen in educational data. For example, in the OECD's (Organisation for Economic Cooperation and Development) series of indicators called "Education at a Glance," the (second) 1993 edition, ran to just over 250 pages--with both English and French text in the same volume. The recently published English language 2013 issue is 435 pages long. Some changes are due to: changes in scope; emerging non-OECD economies; and more tables, columns, topics, and time series. What do these data tell about the impact of education policies in OECD (and other countries)? It is indeed an amazing compendium of data that includes examples of: data on graduation rates, completion rates, earnings premiums, costs and benefits, social outcomes (even including data on the relationship between obesity and smoking and educational attainment), instruction time in schools, teachers' salaries, and hours of work. This data allows countries to analyze pressing policy concerns and work on solutions.
