• The Housing, Household services and Leisure services groups were the largest contributors to the overall annual increase in the RPI
• The increase in the RPI over the twelve months to December 2017 was 3.6%; hence, the annual rate of inflation fell by 0.4 percentage points (pp) in the latest quarter
