Computer science is the most popular subject offered by the world’s top universities. The second and third most popular subjects are mechanical engineering and medicine. 
This is according to the 2013 QS World University Rankings by Subject, published on topuniversities.com, which reveals the top 200 universities in the world for 30 disciplines including degree subjects such as economics, civil engineering, physics and law.
The trend reflects the finding of a recent study of global demand for IT analysts, developers, programmers and engineers. These occupations were found on the national skills shortage lists of 21 OECD and BRICS countries.
The 2013 QS World University Rankings by Subject evaluated 2 858 universities and ranked 678 institutions in total. Massachusetts Institute of Technology (MIT) was once again crowned the top university in the world for computer science, for the third year in a row.
Top 10 institutions in computer science are as follows:
* Massachusetts Institute of Technology (MIT) – US;
* Stanford University – US;
* University of Oxford – UK;
* Carnegie Mellon University – US;
* University of Cambridge – UK;
* Harvard University – US;
* University of California, Berkeley (UCB) – US;
* National University of Singapore (NUS) – Singapore;
* ETH Zurich (Swiss Federal Institute of Technology) – Switzerland; and

Ben Sowter, head of research at QS, says: “The explosions in technology-based start-ups, as well as national security fears of cyber-warfare, have meant that computer science graduates are in great demand with employers.
“As our ranking is the only one to take into account the opinion of employers, our results are closely watched by students who want to increase their chances of employment, as well as those looking to recruit the best talent nationally and internationally.”
