3.1. Data description:Harmonised indices of consumer prices (HICPs) give comparable measures of inflation for Europe, as well as assess monetary value in the euro area. Every EU member country is obliged to produce the HICP.
3.2. Classification system:COICOP 1999; ECOICOP
3.3. Sector coverage:HICPs cover the whole household sector, more precisely the goods and services that are acquired by households (domestic concept).
3.4. Statistical concepts and
       definitions:
The Harmonized Index of Consumer Prices (HICP) measures changes in the level of retail prices of goods and services from the point of view of the expenditure structure, which consumers (domestic and foreign) intend for final consumption in the territory of Montenegro (domestic concept). The HICP is used for monitoring the movement of retail prices in EU Member States, comparing inflation rates between Member States and as the official rate of the European Central Bank (ECB) at ensuring price stability in the Economic and Monetary Union (EMU). Elementary aggregates represent products at the lowest level of aggregation i.e. products in all sales facilities in one geographical location. The monthly inflation rate (m/m-1) measures the change in the average prices of the current month compared to the average prices of the previous month. The annual inflation rate (m/m-12) measures the change in the average prices of the current month compared to the average prices in the same month of the previous year. The cumulative index (rate of change) measures the change in the average prices of the current month compared to the average prices in December of the previous year. The base index (rate of change) measures the average price change in the current month compared to the average of the base year. The average annual index (rate of change) measures changes in average prices from the beginning of the year to the current month compared to the same period of the previous year (e.g. Jan-May 16/Jan-May 15). The weights used for calculation of the HICPs represent a relative share of the selected goods and services in the total household?s consumption, in domestic territory. More precisely, they represent the importance of a particular product group in total household?s consumption in a specific reference period.
3.5. Statistical unit:Each published index or rate of change refers to the 'final monetary consumption expenditure' of the whole household sector of the corresponding geographical entity. Reporting units covers all types of retail shops (stores of all types and sizes, green markets, craft workshops, public service companies, catering, sports and cultural-educational facilities and the like) which have the highest turnover. The observation units are retail prices of final consumption products and services, which have a significant share in the total consumption of the average consumer. These products and services make the basket of goods and services, which includes mainly products and services, whose share in total consumption of the population exceeds 0.1%.
3.6. Statistical population:The target statistical universe is the 'household final monetary consumption expenditure' (HFMCE) within the economic territories of the countries compiling the HICP. HICP covers the consumption of all households at the national territory (residents and non-residernts).
3.7. Reference area:The HICP refers to the whole territory of Montenegro.
3.8. Time coverage:HICPs for Montenegro are available from January 2011.
3.9. Base period:The index reference period is 2015=100.

11.1. Quality assurance:Statistical Office has chosen the implementation of elements of TQM (Total Quality Management) model that foster development and improvement of functioning of: - Institution, - Official statistical result production, and - Individual. Within middle-term deadline, Statistical Office has chosen the TQM implementation through the following objectives: 1. Strong commitment to users and other interested parties, 2. Quality statistical processes and products, 3. Professional orientation of staff members, 4. Constant improvements, 5. Reduction of overburden of reporting units. Collected price data are checked and edited in several steps. First, the price collectors' notes and signal indications regarding model changes, missing prices etc. are reviewed. Checks are made for missing or duplicate price records. Then, lists for editing are iteratively produced and reviewed to check for unexpectedly deviating prices, etc. This is to ensure that such data are not due to mistakes in processing, and the data are edited as and when needed. The price collectors' judgmental valuations of quality changes are also reviewed in this process. There is no automatic rejection, all suspicious data are re-checked by collectors.The price collectors or outlets are contacted for further information on specific cases when necessary. Centrally collected prices are entered into the system by central office staff. Department for Price Statistics do validation, calculation and checking of the preliminary indices, comparing with the data from the previous periods. After detailed control and data analysis, the final data are prepared for publication and submitted to the supervisors for final verification.
11.2. Quality assesment:The quality of the HICP is assessed to be high considering that its concepts and methodology have been developed according to international standards and using consumer price statistics experience from all EU Member States. HICPs are considered to be sufficiently accurate for all practical purposes they are put into. Further work is ongoing to improve the quality and in particular comparability of the index.

15.1. Comparability -
          geographical:
HICP is produced based on HICP minimum standards. Requirements of EU regulations harmonizing HICP definitions and classifications have been implemented into Montenegrin HICP. There is some difficult areas which can be improved (particularly quality adjustment) in order to further improve the comparability. Definitions and classifications have been harmonised in a series of legal acts that have resolved conceptual disparities. HICPs are produced based on minimum standards, which may be applied with some flexibility as long as the effect on the value of the indicator remains below 0.1%.
15.2. Comparability over time:HICP data are considered to be comparable over time. MONSTAT has been produced HICP data from January 2011 and are available on website, within section Data.

15.3. Coherence - cross
          domain:
Differences between the HICP and national CPI Different population coverage: The HICP covers the consumption expenditure of non-residents and institutional households within the economic territory of the country, while they are not included in the national CPI. Different data sources for the calculation of weights: The main data source for the HICP weights is the National Accounts data, while the main data source for the CPI weights is the Household Budget Survey.
15.4. Coherence - internal:HICPs are internal coherent. Higher level aggregations are derived from detailed indices according to well-defined procedures.

17.2. Data revision - practice:The data are published as final and are not subject to any revision (unless an error or mistake is found), a fact which is noted in the publications. Major changes in the methodology (classification changes, index reference period, etc.) are announced in the frame of montlhy release Harmonised Index of Consumer Prices at the time the change is introduced.

                                                                                 18. Statistical processing                                                                 Top
18.1. Source data:The selection of weights: Weights are structure of household consumption obtained on the basis of HBS data. Selection of shops: Criteria for selection of number and type of shops in one town are: -Type of product or service for which prices are collected -Number of population -Turnover achieved -Price balance of the same product in different shops -Continuous supply of goods in shop -Consumer's habit -Location Number of population and product type are the main criteria for selection of number of shops by towns. Due to permanent presence in the field and facing real situation, price collectors, in cooperation with the Price Statistics Department, will take a final decision on selection of collecting places. Selection of shops for price collection is updated every year. Selection of products: The list of products for which the prices are collected is uniform for entire Montenegro. A final list for price collection is defined by Statistical Office, i.e. Price Statistics Department, after the consultation with price collectors, up to the end of November at the latest. Price collector selects a product that match to the product description from the product list. If in a shop there are several different products that correspond to the appropriate description, it is selected one that is sold the most in longer time period. Due to this, it is very important that when selecting a product, a sale person is consulted. When a product is selected for which the price will be collected, it is unchanged during an entire year.
18.2. Frequency of data
          collection:
For the purposes of calculation of the HICP, prices are collected once a month in the period from the 3rd to 25th of the month, except for the prices of fuel which are collected on a daily basis.
18.3. Data collection:Price data are collected on a monthly basis for selected goods and services, collected by engaged interviewers in 5 municipalities: Podgorica, Niksic, Bijelo Polje, Bar and Budva. A certain number of prices is collected at the centralized level in the Price Statistics Department. Collection methods are different and depend on type of product or service (phone interview, Internet or special questionnaires)
18.6. Adjustment:During a year, price adjustments due to quality changes are most frequently made for cars, PCs, major household appliances, clothing, and technical products. The following methods are used: - Explicit methods Direct price comparison: e.g. clothing - as required Option pricing: new cars - as required Judgmental QA: e.g. clothing, cars - as required Package size adjustment: e.g. food and medicaments Mixed approaches: - as required - Implicit methods Overlap: e.g. audio visual goods - as required Bridge overlap: e.g. PCs, technical products, household appliances - as required.
