Re-referencing of the CPI and CPIH and Introduction of the COICOP5 classification

This note sets out two important forthcoming developments for the Consumer Prices Index (CPI) and CPIH (a measure of inflation that includes owner occupiers’ housing costs), due to be implemented in early 2016. The first of these is a re-referencing of the indices to 2015=100. The second is the introduction of a more detailed level of sub-category known as COICOP5.
