World Rugby Chairperson, Bernard Lapasset, commented: "Rugby World Cup 2015 will be remembered as the biggest and indeed the best tournament to date, reaching and inspiring new audiences in record numbers. New Zealand were worthy champions but this report clearly underscores why rugby was the winner.
"At the very heart of the success story was the compelling action on the field which saw rankings upsets and the smallest average winning margin across the 48 matches and more significantly, the smallest average winning margin between the world's top teams and emerging rugby powers, highlighting the ever-increasing competitiveness of the global game.
"World Rugby continues to be committed to closing the performance gap as we enter a new Rugby World Cup cycle and look forward to the first tournament to be hosted in Asia. We will continue to act on the learnings from 2015 and invest in structures and competitions that will assist emerging nations take the next step-up and challenge for quarter-final places in Japan."
