        Most of the papers analysing ranking results only use the data from the top 500 universities, a sample that is clearly not very representative for most of the countries. For example, although there are countries where the whole set of their universities are in the upper category, others as important as the USA, that has a lot of universities in the elite, also shows over 2000 of its HEIs beyond the 5000th mark.
