| 2.1 Concepts and definitions | 2.1.1 Concepts and definitions Definition: CPI is a relative indicator characterizing the overall change in the value of the purchased buyer's purchased goods and the amount of the service purchased. |
| 2.2 Scope | 2.2.1 Scope • Scope of the data • Population coverage: Consumption costs of the population used to calculate the Consumer Price Index cover all private households except for foreigners and stateless persons living in Azerbaijan. • Geographical coverage: Price observation is conducted in 58 cities (regions) of the country, so the index covers all territory of the Republic of Azerbaijan. • Item coverage: The CPI calculation is based on prices of 528 products and services (food - 151, non-food - 274 and services - 103) •Exceptions to coverage Goods (services): Conventionally calculated rent for owner-occupied housing |
| 2.3 Classification/ sectorization | 2.3.1 Classification/sectorization • Classification: Goods and services are classified according to the national version of “Classification of Individual Consumption According to Purpose” (COICOP) • Relationship with international guidelines: The CPI calculation is based on the international standards, including the 2004 "Consumer Price Index Guidelines: Theory and Practice" methodological manual adopted by the UN, IMF, ILO, Eurostat, OECD and the World Bank |
| 2.4 Basis for recording | 2.4.1 Valuation Types of prices: CPI characterizes the change in actual prices reflecting the VAT, excise and other direct taxes on the goods (service) in the free market, as well as the cost and profit of the commercial organizations 2.4.2 Recording basis Timing of Price Observation: Consumer price registration is implemented ‘three times a month in food products (ten days interval), non-food products and paid services for the population in the third decade. |
| 3. Accuracy and reliability | |
| 3.1 Source data | 3.1.1 Source data collection programs • Source of weights: Data on household budget surveys related to the structure of final consumption expenditures of the population are used. •Timing of current weights: Available weights refer to 2019. •Frequency of weight updates: The weights are updated every April to calculate the CPI. • Item selection: Regularly traded local production and import goods are involved in observation in accordance with medium purchaser power consumer basket. •Outlet selection: Representative selected outlets of all property and organizational-legal forms, markets as well as places where goods are sold and services are provided to citizens, are involved in observation taking into account the regularity, popularity of goods sold, services rendered to and the sale of local and imported goods. • Sample size: Prices of more than 500,000 goods and services from 5283 outlets are observed every month. •Price collection methods: Data on 8 large trade networks, which make 20 per cent of the trade turnover in Baku, are obtained in an electronic form (scanned) directly from the trade network, and from other outlets - in a tradition way by relevant experts of local statistical agencies through tablet computers in online mode. •Item/service specification: Detailed description of each item and service specification is provided in the list of goods (services) included in the consumer basket formulated for price observation. |
| 3.3 Statistical techniques | 3.3.1 Source data statistical techniques •Computation of lowest level indices: The geometric mean is used for computation of lowest level indices. •Aggregation: A modified Laspeyres formula is used to calculate the aggregate price indexes. •Linking reweighted index to historical index: "Reweighted" price index is divided into "historical" price index and coefficient is derived and used for linking indexes. • Reference period: 2010=100. 3.3.2 Other statistical procedures • Treatment of missing prices: In order to avoid the effects of seasonal factors on the consumer price index and to ensure continuity of price indices,"conventionally" calculated prices are used for commodities which disappear or their sale is sharply limited in the consumer market for certain periods of the year (imputation method) • Adjustments for quality differences: Quality differences are taken into account during the calculation of price indexes. • Introducing new products Key condition to introduce goods (services) to sample (consumer basket) is that it should have a high share in the consumer market and consumption expenditure structure. •Seasonal items: Conventionally calculated prices are applied to products which disappeared due to seasonal factors. • Owner occupied housing: The price index of conventionally calculated rent for owner-occupied housing is not calculated. However, price indices in the housing market and the price indices of goods and services used to maintain and repair of private housing in the structure of CPI are calculated. |

When there is a doubt whether any of the primary data included in the database within the reference period is reflecting the truth, this information is verified once again and adjusted if necessary. •Verification of processing: All the stages of the data processing are monitored and checked |
