On June 13 2018, the RSS hosted an important and well-attended meeting on ‘The Future of the RPI’, bringing together many distinguished speakers, including the UK National Statistician John Pullinger (pictured), representing a broad spectrum of opinions.
In 2011, the Office for National Statistics carried out a comprehensive investigation into one of the formulae (Carli) used in the compilation of the RPI and concluded it was flawed. However, a consultation in late 2012 showed an overwhelming majority in favour of keeping the RPI formulae unchanged so that the behaviour of the index was not altered. Acknowledging this, the National Statistician of the time decided not to change the formula and also to 'freeze' its compilation but at the same time to discourage its use. In 2013 the RPI lost its national statistic status. It remains, however, widely used.
