Classification structure
2 (a)Please describe the structure of the classification: How many levels does the classification have? (Please provide labels, such as “Division”, “Class”) How many categories exist at each level?Consumer goods and services included in the Consumer Price Indices (CPIs) and Household Expenditure Survey (HES) statistics are classified into a hierarchical system which consists of four levels, namely, section, group, sub-group and item. In the 2009/10-based CPIs, there are nine commodity/service sections,
94 groups, 241 sub-groups and 980 items.
2 (b)Please provide examples of the coding system used at each level.For HKCC, a particular commodity/service item is assigned with a 7-digit code, where the first digit denotes the section, the first three digits denote the group and the first five digits denote the sub-group.
 
Relationship to international standards
3 (a)Is this classification based on (or linked to) an international standard classification? If yes, please describe.When analysing the CPIs and HES statistics, Hong Kong has all along adopted a classification system for commodities/services (i.e. Hong Kong CPI Classification) which has evolved over time to meet user requirements and local situation.
In addition to the HKCC, the CPIs and HES statistics based on the Classification of Individual Consumption According to Purpose (COICOP) are also compiled to facilitate international comparison. In particular, annual rates of change in the CPIs based on COICOP at division level from reference year 2006 onwards have been published; and the average monthly household expenditure statistics by COICOP division have been published in the 2004/05 and 2009/10 rounds of HES.
3 (b)Is the classification structure identical to the international standard or, if not, how does it differ? (e.g. have additional levels been added to the international standard or have changes been made within the level of the international structure, such as aggregations or additional breakdowns)No. The HKCC includes 9 commodity/service sections such as "Food", "Housing", "Electricity, gas and water", "Alcoholic drinks and tobacco", "Clothing and footwear", "Durable goods", "Miscellaneous goods",
"Transport" and "Miscellaneous serivces".
3 (c)Please describe deviations from the international standard (in terms of structure, methodology or application rules). Please use examples, if a general statement is not possible.The classification on the basic necessaries, viz clothing, food, housing, and transport, are similar under HKCC and COICOP, with only minor difference in the number of food-related and housing-related sections. For instance, there is only a single "Food" section in HKCC which covers both basic food and food consumed at restaurants, but there are 2 separate food-related sections, namely "Food and nonalcoholic beverages" and "Restaurants and hotels" under COICOP. On the other hand, expenditure on
"Housing" and "Electricity, gas and water" are classified into 2 separate sections in HKCC, but combined into a single section in COICOP.

The major difference between the two classifications in fact lies on the classification of the non-basic necessaries. Instead of classifying the non-basic necessaries into goods and services in HKCC (i.e. "Durable goods", "Miscellaneous goods" and "Miscellaneous services"), they are classified into 6 divisions, namely "Furnishings, houshold equipment and routine household maintenance", "Health", "Communication", "Recreational and culture", "Education" and "Miscellaneous goods and services", in
COICOP according to the purpose of transactions. For example, "medicines" and "medical services" are classified under "Miscellaneous goods" and "Miscellaneous services" separately in HKCC but grouped under a single division "Health" in COICOP. Similarly, "Video and sound equipment" and "Package tour" are classified under "Durable goods" and "Miscellaneous services" respectively in HKCC but grouped
under a single division "Recreation and culture" in COICOP.

3 (d)At what level of the international standard can data be reported for international comparison? (Please provide examples of programmes / indicators if reporting takes place at different levels of the classification.)COICOP at division and group levels.
3 (e)If no links to international classifications exist or no international standard is used, please state if there are plans to use international norms in the future.Not applicable.
 
Classification uses
4 (a)Please state for which statistical purposes (surveys etc.) this classification is used and if there are users outside of the Statistical Office. Please indicate at which level the classification is used for data collection and for data publishing.The HKCC is used for compilation of CPIs and demarcation of household expenditure in HES. While more detailed classification of commodities/services at item level is used for data collection, broader classification at section and group levels is used for data publishing.
4 (b)Please give the names of institutions that use the classification for non-statistical purposes (as opposed to statistical purposes in question 4(a)). Also indicate the kind of use (e.g. tax offices, social security, customs, enterprise register, employment services, work permits etc.)Not applicable.
4 (c)Please indicate if alternative classifications are used by other institutions of the economy. Are these classifications available and useful for the Statistical Office?Not applicable.
 
Implementation / revision status
5 (a)Please state the date of the official adoption of the classification. If not yet adopted, please indicate the current state (e.g. in development, sent for approval, in printing, ready to be distributed etc.)The CPIs have been published according to the HKCC since 1973/74-based CPIs.
Annual rates of change in the CPIs based on COICOP at division level since reference year 2006 have been published in the form of feature article in the Hong Kong Monthly Digest of Statistics (HKMDS) and also included in the Annual Report on the Consumer Price Index. Further breakdowns at COICOP group level are also available upon request.
5 (b)Please state the date of use of the classification for individual statistical programmes.Not available.
5 (c)Are there existing plans for revision or update of the current classification?The framework of HKCC together with the goods and services covered in the CPI basket will be reviewed regularly every 5 years by making reference to the results of the Household Expenditure Survey (HES). The currently adopted classification of CPI is 2009/10-based which was reviewed based on the results of the 2009/10 HES.
5 (d)Name of former (previous) national classification (full name in both national tongue and in English with acronyms in brackets, should be given)Not applicable.
5 (e)Please describe the link of the former classification to international classificationsNot applicable.
5 (f)Please describe the structure of the former classification and indicate the number of items at each level of the classification. (similar to question 2(a))Not applicable.
5 (g)Do conversion tables exist between the former and current classification?Not applicable.
5 (h)When was the former classification implemented?Not applicable.
5 (i)Are statistical data still collected or published according to the former classification? Please indicate if this statistical data is collected or published by the Statistical Office or elsewhere.Not applicable.
