Only the universities of Oxford and Cambridge were significantly more elite than the majority of ``old'' universities when a grouping analysis was performed using data on academic selectivity, research activity, teaching quality, socio-economic exclusivity and economic resources. The other 22 members of the Russell Group sit in a second tier of universities along with 18 other ``old'' universities (University of Aberdeen, University of Bath*, University of Keele, University of Dundee, University of East Anglia*, Goldsmiths*, Heriot-Watt University, University of Kent, Lancaster University*, University of Leicester*, Loughborough University*, University of Reading*, Royal Holloway*, University of St Andrews*, SOAS*, University of Strathclyde, University of Surrey* and University of Sussex*), mostly comprising former members of the defunct 1994 Group (shown by asterisks). Another 13 ``old'' universities and 52 ``new'' universities made up a third tier, with a fourth tier of 19 ``new'' universities. Within each tier, the differences between the institutions were less significant than the differences between the tiers. This reflected an earlier result from 2010 that, when the ``Golden Triangle'' universities (defined in the study as Oxford, Cambridge, Imperial, LSE, and UCL) were omitted, the remaining (then) members of the Russell Group were outperformed by the (then) members of the 1994 Group.
