Contributions to the overall CPI – annual change

Table 17 shows the contribution of each 2-digit COICOP1 division to the overall change in the CPI.  A detailed breakdown of the individual components of each of the 12 COICOP divisions is presented in Tables 4 to 15.

The divisions which caused the largest upward contribution to the CPI in the year were Transport (+1.45%), Housing, Water, Electricity, Gas & Other Fuels (+1.43%), Restaurants & Hotels (+0.36%) and Alcoholic Beverages & Tobacco (+0.32%).

The divisions which caused the largest downward contribution to the CPI in the year were Clothing & Footwear (-0.13%) and Miscellaneous Goods & Services (-0.02%).

The main factors contributing to the annual change were as follows:

  • Transport increased primarily due to higher prices for diesel, petrol and motor cars, an increase in airfares and a rise in the cost of services in respect of personal transport equipment.
  • Housing, Water, Electricity, Gas & Other Fuels rose mainly due to higher rents and mortgage interest repayments and an increase in the cost of electricity, home heating oil and gas.
  • Restaurants & Hotels increased primarily due to higher prices for alcoholic drinks and food consumed in licensed premises, restaurants, cafes etc.
  • Alcoholic Beverages & Tobacco rose due to an increase in the cost of tobacco products and higher prices for alcoholic beverages sold in supermarkets and off licences.
  • Clothing & Footwear fell due to sales.
  • Miscellaneous Goods & Services decreased primarily due to lower motor insurance premiums and a reduction in prices for articles & products for personal care and jewellery, clocks & watches.  This decrease was partially offset by higher health insurance premiums.

  • Restaurants & Hotels decreased due to lower prices for hotel accommodation.
