How U.S. News Calculated the Best Global Universities Rankings

The inaugural U.S. News Best Global Universities rankings were produced to provide insight into how universities compare globally. As an increasing number of students are planning to enroll in universities outside of their own country, the Best Global Universities rankings – which focus specifically on schools' academic research and reputation overall and not their separate undergraduate or graduate programs – can help those students accurately compare institutions around the world. 
The Best Global Universities rankings also provide insight into how U.S. universities – which U.S. News has been ranking separately for the last 30 years – stand globally. All universities can now benchmark themselves against schools in their own country and region, become more visible on the world stage and find top schools in other countries to consider collaborating with.
The overall Best Global Universities rankings encompass the top 500 institutions spread out across 49 countries. The first step in producing these rankings, which are powered by Thomson Reuters InCitesTM ​research analytics solutions, involved creating​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​ ​a pool of 750 universities that was used to rank the top 500 schools.
To be included in the 750, an institution had to first be among the top 200 universities in the results of Thomson Reuters' global reputation survey, described further below.​ Next, an institution had to be among those that had published the most number of ​articles during the most recent five years, de-duplicated with the top 200 from the reputation survey.
As a result of these criteria, many stand-alone graduate schools, including the Rockefeller Institute of New York and University of California—San Francisco, were eligible to be ranked and were included in the ranking universe.
The second step was to calculate the rankings using the 10 indicators and weights that U.S. News chose to measure global research performance. Each school's profile page on usnews.com lists numerical ranks, out of 750, for the 10 indicators, allowing students to compare each school's standing in each indicator.
The indicators and their weights in the ranking formula are listed in the table below, with related indicators grouped together;​ ​an explanation of each follows.
