Figure C4: Mean revisions to quarterly volume GDP growth by Blue Book
Source: Office for National Statistics
The revisions in each Blue Book relate to the period from Quarter 1 1997 to the latest quarter available in that publication. The exception here is Blue Book 2019, where indicative estimates up to Quarter 4 2016 are only included.
Blue Book 2011 includes the switch from RPI to CPI.
The chart is calculated on the revisions between a Blue Book round and the preceding vintage.
