According to the 'Patterns 3' report by Universities UK, "The Russell Group and the 1994 Group share many features, but are distinguished chiefly by the fact that most members of the Russell Group have medical schools, and an emphasis on science and technology. Within the Russell Group a small number of institutions are outliers on the basis of the statistical information available, and if these were excluded from the analysis, the Russell Group and the 1994 Group would show very similar characteristics."
