The graphic above displays a world map distorted relative to the population of each country and has pink bubbles indicating the location of the top 200 ranked universities in the world. The relative size of the bubbles indicate that the university is located closer to the top of the rankings and vise versa for smaller bubbles. What is striking about this map is the inequality of top universities globally, with virtually all of the top 200 schools located in the developed world.
Further, the concentration gets even more extreme at the very top of the rankings. From the 2015 numbers, the top 50 universities in the world are located in just 12 countries. The United States has a huge advantage in premier universities with 25 of the top 50 and 10 of the top 15! The next closest on the list is the United Kingdom with 7 in the top 50 (3 of these 7 in the top 10 – Oxford, Cambridge, and Imperial College London).
North America, Europe, and Australia account for 45 of the top 50 universities in the world. The remaining 5 located outside the western world are: National University of Singapore (26th), Peking University (42nd), University of Tokyo (43rd), University of Hong Kong (44th), and Tsinghua University (47th).
