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 Housing, Water, Electricity, Gas & Other Fuels (+0.54%), Restaurants & Hotels (+0.46%) and Transport (+0.12%).

The divisions which caused the largest downward contribution to the CPI in the year were Furnishings, Household Equipment & Routine Household Maintenance (-0.17%), Clothing & Footwear (-0.16%) and Food & Non-Alcoholic Beverages (-0.14%).

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

  • Housing, Water, Electricity, Gas & Other Fuels rose mainly due to higher rents and an increase in the price of electricity and home heating oil.
  • Restaurants & Hotels increased primarily due to higher prices for alcoholic drinks and food consumed in licensed premises, restaurants, cafes etc. and an increase in the cost of hotel accommodation.
  • Transport rose mainly due to higher petrol and diesel prices which was partially offset by a reduction in the price of motor cars.
  • Furnishings, Household Equipment & Routine Household Maintenance fell primarily due to the reduced cost of furniture & furnishings, non-durable household goods and household textiles.
  • Clothing & Footwear decreased due to sales.
  • Food & Non-Alcoholic Beverages fell due to lower prices across a range of products such as vegetables, bread & cereals, jam, honey, chocolate & confectionery and meat.

Contributions to the overall CPI – monthly change

The divisions which caused the largest downward contribution to the CPI in the month were Restaurants & Hotels (-0.14%) and Miscellaneous Goods & Services (-0.08%).  The divisions which caused the largest upward contribution in the month were Clothing & Footwear (+0.09%) and Housing, Water, Electricity, Gas & Other Fuels (+0.06%). 

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

  • Restaurants & Hotels fell due to lower prices for hotel accommodation.
  • Miscellaneous Goods & Services decreased primarily due to lower prices for other appliances, articles & products for personal care and a decrease in the cost of health and motor insurance.
  • Clothing & Footwear increased due to a recovery from sales.
  • Housing, Water, Electricity, Gas & Other Fuels rose mainly due to a rise in the cost of home heating oil and an increase in the price of electricity and gas which was partially offset by lower mortgage interest repayments.

CPI sub-indices

The sub index for Services rose by 1.9% in the year to November, while Goods decreased by 1.5%.  Services, excluding mortgage interest repayments, increased by 2.1% in the year since November 2016.

Background Notes

Consumer Price Index

Definition

The Consumer Price Index is designed to measure the change in the average level of prices (inclusive of all indirect taxes) paid for consumer goods and services by all private and institutional households in the country and by foreign tourists holidaying in Ireland.

Consumer Price Index (CPI)

Approximately 51,000 prices are collected for a representative basket consisting of 615 item headings in a fixed panel of retail and service outlets throughout the country during the week containing the second Tuesday of each month up to and including the third Tuesday of each month.

Scope of the Index

  1. Population Coverage: All private and institutional households in the State and the expenditure of foreign tourists within Ireland.  It does not include the expenditure of other non-private households.    Expenditure which occurs abroad by Irish residents is also excluded.  In statistical terms coverage is referred to as the domestic concept.
  2. Geographic Coverage: Covers the whole of the Republic of Ireland.  Pricing takes place in 84 locations (cities and towns) throughout the country.  These sampling points are located in Dublin city and county, the four regional cities of Cork, Limerick, Galway and Waterford, approx. 80% of towns with a population of 10,000 and over, approx. 70% of towns between 5,000 and 9,999 and a smaller proportion below this threshold.  The results are weighted to represent the distribution of the population and its related consumer expenditure.
  3. Item Coverage: All goods and services bought by the reference population for the purposes of consumption are included in the index.  Expenditure on capital assets and investments, gambling and certain other activities are however excluded.  There are 615 item headings and 12 division headings based on the COICOP classification.  With each rebase the coverage of goods and services is reviewed to ensure that it continues to be representative of consumer tastes and purchasing practices.

Personal visits are made to retail outlets by some 80 price collectors on a monthly basis.  Approximately 48,000 price quotations are gathered in this way.  In addition, 137 special inquiries covering items such as utility charges and services are conducted by post, telephone and e-mail in conjunction with internet price collection.  Most prices are collected monthly, some quarterly and others annually.  The CSO supplies general specifications to price collectors and price collectors are free initially to select a brand and in certain cases, size.  This allows for a wide variety of different brands of the same item to be priced throughout the country.  Once selected, the same item/brand is priced on a monthly basis in order to ensure matched price quotations.  If an item disappears, substitution can occur but that price is excluded until matched prices are available for the same comparable item for two consecutive months.  The CSO wishes to put on record its appreciation of the co-operation and assistance it receives from retail outlets and other business concerns.

Classification

The classification used in the CPI is based on a version of the Classification of Individual Consumption by Purpose Adapted to the Needs of Harmonised Indices of Consumer Prices (2000) (COICOP).  This replaced the former national classification which was used up to December 2001.  The COICOP classification breaks consumer expenditure into twelve different divisions covering a comprehensive range of consumer goods and services.

Annual Update of CPI Weights

Since 2012 the weights of the items in the basket have been updated annually at CPI COICOP class (4-digit) level using information on consumer expenditure from National Accounts Household Final Monetary Consumption Expenditure (HFMCE). Additionally at the 2016 rebase, a more granular level update of the weights (5-digit) was possible using information from the latest Household Budget Survey (HBS) which was carried out between February 2015 and February 2016.

CPI Item Weights

The CPI measures in index form the monthly changes in the cost of purchasing a fixed representative ‘basket’ of consumer goods and services (i.e. Laspeyres formula).  Identical items are priced in the same outlet on each occasion so that changes in the cost of this constant basket reflect only pure price changes. The current basket of goods and services consists of 615 representative items which were predominantly selected as part of the December 2016 rebase.  The representative share of each item in the basket is proportional to the average amount purchased by all households in the State and foreign tourists in Ireland based primarily on the 2015/2016 Household Budget Survey (HBS) and estimates of expenditure by foreign tourists across a range of consumer goods and services.  

Methodological Details

A full methodological description of the new series is available in the CPI - Introduction of Updated Series (Base December 2016=100) (PDF 1,524KB) which is published on the CSO website. 

Rebase

The index has been rebased with effect from December 2016.

The rebase of the current CPI resulted in a number of methodological changes:

  • Updating the expenditure weights;
  • A revision of the sample of goods and services;
  • Improved methods of price collection

Goods and Services

Goods

Goods are defined as non service items usually purchased and transportable from a retail outlet.

Services

Services include the following: rents, mortgage interest, services for the maintenance & repair of the dwelling, water supply & miscellaneous services relating to the dwelling, electricity, gas, repair of household appliances, tool hire, domestic services & household services, out-patient services, hospital services, maintenance/repair and other services in respect of personal transport equipment, transport services, postal services, telephone services, repair of audio-visual, photographic & information processing equipment, veterinary & other services for pets, recreational & cultural services, package holidays, education, catering services, accommodation services, hairdressing salons & personal grooming establishments, social protection, insurance, financial services n.e.c. and other services n.e.c.

Utilities and Local Charges

Includes electricity, natural gas, refuse collection, sewage collection, water supply and telephone services – landline.

Mortgage Interest and the Local Property Tax in the CPI

Mortgage interest was first included in the CPI at the November 1975 rebase. The use of mortgage interest in the CPI reflects a user-cost approach to measuring owner-occupied housing.  This approach has involved measuring changes in average mortgage interest costs over time.  The household charge was introduced to the CPI in April 2012 and subsequently became the local property tax in July 2013. The local property tax is included in the basket under the item 'miscellaneous goods and services', which is part of COICOP 12.7.0.  The inclusion of the local property tax is consistent with the user-cost approach utilised for owner-occupied housing.  In the interest of transparency, an index excluding both mortgage interest and the local property tax is provided in Table 2 of the release to allow for their impact in the CPI to be seen.

Mortgage interest and the local property tax are excluded from the HICP.   

Water supply and sewage collection charges

Water supply and sewage collection charges were introduced in Ireland on 1 January 2015.  The coverage of the CPI/HICP is defined as those goods and services purchased by households for the purposes of consumption.  This definition required the incorporation of the new charges into the CPI/HICP.  Water supply and sewage collection charges are a component of group 04.4 Water supply & miscellaneous services relating to the dwelling of the COICOP consumption classification.  Water supply and sewage collection charges were suspended for a period of nine months from 1st July 2016. 

For a full discussion on the rationale and methodology for introducing water supply and sewage collection charges into the CPI/HICP, see the relevant CPI Technical Paper Introduction of Water Supply and Sewage Collection (PDF 593KB) .

Harmonised Indices of Consumer Prices

Introduction

The European Union-Harmonised Indices of Consumer Prices (EU-HICP) is calculated in each Member State of the EU.  The purpose of this index is to allow the comparison of consumer price trends in the different Member States.

Comparison with CPI

The methodology now adopted for the construction of the national CPI is identical to that recommended for the HICP.  Thus the two indices only differ in respect of the coverage of certain goods and services and the treatment of insurance.  The current EU reference base period (Year 2005=100) is however retained for ease of comparison with other EU countries.

Excluded Items

The following items, constituting approximately 6.2% of the Irish CPI expenditure weighting, are excluded from the HICP:

  • mortgage interest
  • building materials
  • motor car tax
  • motor cycle tax
  • motor car insurance (non-service)
  • contents insurance (non-service)
  • dwelling insurance
  • union subscriptions
  • local property tax 

Annual Update of HICP Weights

For 2017, the CPI COICOP class (4-digit) level weights were updated with a reference period of December 2016 using information on consumer expenditure from HFMCE.  The expenditure data were price updated at HICP COICOP class level to December 2016 using the price movement of the corresponding HICP COICOP class indices. Additionally at the 2016 CPI rebase, a more granular level update of the weights (5-digit) was possible using information from the latest 2015/2016 HBS. The expenditure data were price updated at HICP COICOP class level using the price movement of the corresponding HICP COICOP class indices.

Monetary Union Index of Consumer Prices (MUICP)

Euro area inflation is measured by the MUICP (‘Monetary Union Index of Consumer Prices’ as defined in Council Regulation (EC) No 2494/95 of 23 October 1995) which is the official euro area aggregate.  The MUICP is calculated as a weighted average of HICPs of the 18 countries in the euro area.  Country weights are computed every year reflecting the country’s share of the household final monetary consumption expenditure in the euro area total.

Classification System

The coverage of the indices is based on the international classification system, Classification of Individual Consumption by Purpose Adapted to the Needs of Harmonised Indices of Consumer Prices (2000) (COICOP).

COICOP

Prior to the introduction of the December 2001 based series in January 2002 the CPI used a national classification while the EU Harmonised Indices of Consumer Prices (HICP) used COICOP.  To ensure greater comparability CPI and the HICP have both used the COICOP since December 2001.

The COICOP classification is based on 12 divisions:

01    Food and Non-Alcoholic Beverages

Includes food and non-alcoholic beverages purchased in supermarkets, small shops, speciality shops and petrol station forecourt outlets.  It excludes meals out which are covered under 11 Restaurants and Hotels.

02    Alcoholic Beverages and Tobacco

Includes alcoholic beverages purchased in off licences and supermarkets but excludes alcohol consumed on or within licensed premises which is classified under 11 Restaurants and Hotels.  It also includes tobacco products.

03    Clothing and Footwear

Men's, ladies and children's clothing and footwear, sports and leisurewear and services such as laundry and dry cleaning, shoe repair, dress hire and alteration.

04    Housing, Water, Electricity, Gas and Other Fuels

Covers rents, mortgage interest repayments, refuse collection, goods and services for maintaining, decorating and repairing dwellings and domestic energy products such as electricity, gas, home heating oil and solid fuels.  Water supply and sewage collection were added to this division under the item 'water supply and miscellaneous services relating to the dwelling' in January 2015.

05    Furnishings, Household Equipment and Routine Household Maintenance

Covers household items such as furniture, carpets and other floor coverings, household textiles and soft furnishings, household appliances and other household items such as utensils, tools, garden equipment and non-durable items for cleaning, washing and other day to day household activity.  Also included are services such as electrical repair, cleaning and gardening.

06    Health

Includes medical products, appliances and equipment, hospital charges and outpatient services supplied by doctors, dentists, opticians, physiotherapists and practitioners of alternative and complementary medicine.

07    Transport

Includes the purchase of new and second hand vehicles, spare parts, car maintenance, fuels and lubricants, public transport and services such as parking, motor association subscriptions, car wash, toll charges, driving lessons, driving test, driving licence and car hire.

08    Communications

Postal and telecommunications services.

09    Recreation and Culture

Includes items such as audio visual and photographic equipment, computers, music and DVDs, sports and recreation goods, games and toys, items connected with gardening and pets, recreational, sporting and cultural activities and events, newspapers and other reading material, package holidays and other items connected with recreation and culture.

10    Education

Includes pre-primary and primary, secondary, third level fees and other education and training such as night courses and examination fees.

11    Restaurants and Hotels

Includes meals in restaurants and hotels, fast food and takeaways, cafes and canteens; alcohol consumed on or within licensed premises and accommodation services supplied by hotels, guesthouses and hostels.

12    Miscellaneous Goods and Services

Covers a wide range of items including hairdressing; goods for hygiene, hair and body care; personal goods such as jewellery, handbags and wallets; childcare and other social protection services; insurance, financial services and other services including funerals, weddings, legal and professional services.  The household charge was added to this division, in the CPI, under the item 'miscellaneous goods and services' in April 2012.  The household charge subsequently became the local property tax in July 2013. The local property tax is not included in the HICP.

Calculating percentage changes in the index

The movement of the CPI, HICP and their subindices are expressed as percentage changes, rather than changes in index points, because index point changes are affected by the level of the index in relation to its base period, whereas percentage changes are not.  The example below illustrates the computation of index point and percentage changes.

 

Index point change  
Current index 106.7
Less previous index 103.7
Equals index point change 3.0
   
Percentage change  
Index point change 3.0
Divided by the previous index 103.7
Equals 0.0289
Result multiplied by 100 0.0289 x 100
Equals percentage change 2.9

 

Estimating Contributions

A contribution represents the amount of the overall percentage change in the All Items CPI which is accounted for by any given category.  It can be estimated for any category in the CPI (e.g. the twelve COICOP 2-digit divisions) and for any period of time.

Data Required:

  1. Base weight for the category for which you wish to estimate the contribution.
  2. Current index for the category in question (same base period).
  3. Previous index for the category in question (same base period).
  4. All Items CPI for the previous period in question (i.e. the start period).

Example:

To estimate the contribution of Food & Non-Alcoholic Beverages (COICOP 01) to the overall annual percentage change in the CPI up to July 2006 you would need the following data

 

1 Base weight for COICOP 01 (base:December 2001=100) 14.092%
2 Current Index (i.e. July 2006) for COICOP 01 103.7
3 Previous Index (i.e. July 2005) for COICOP 01 102.1
4 All Items CPI for the previous period (i.e. July 2005) 111.3

                        

Steps in the calculation

Step 1 Multiply the base weight by the current index 14.092 x 103.7
  Equals (1) 1461.3404
Step 2 Multiply the base weight by the previous index 14.092 x 102.1
  Equals (2)  1438.7932
Step 3 Subtract figure (2) from figure (1) 1461.3404 - 1438.7932
  Equals (3) 22.5472
Step 4 Divide figure (3) by the All Items CPI for the previous period 22.5472 / 111.3
  Equals Contribution 0.20

                                                                                                                                              

Therefore your estimated contribution of Food & Non-Alcoholic Beverages to the percentage change in the CPI for the year to July 2006 is 0.20.  The actual published figure was 0.19.  The difference is due to the fact that actual published contributions are calculated using data to more decimal places.

It is more complicated to estimate contributions where more than one base period is involved, as the base weights will have changed (e.g. to estimate a contribution for the period January 2000 to January 2005 involves the November 1996=100 base and the December 2001=100 base).  For assistance in this regard please contact the CPI section.
