Dear,
Thanks a lot for publishing the Nature Index 2017. Since the list contains various sizes of institutes, it would in some cases be interesting to be able to correct on size etc. Is there any way that the Nature Index would also include a column about the size of the research pool in each of the institutions in the list ? This would improve the way we can analyse the data

The order of output of institutions can differ significantly depending on the measure used to order them (AC, FC or WFC). There are many factors determining an institution’s output. The size of the institution is a major factor as is the composition of research specialities within an institution. The Nature Index does not attempt to normalize data for such factors. Rather it presents raw data that can be used as a basis for analysis
