Slovenia - Consumer Price Index (CPI)

For Slovenia, the monthly national CPI organized by ECOICOP ver. 2.

The consumer price index measures changes of the level of retail prices of goods and services from the point of view of the expenditure structure, which the resident population intends for final consumption at home and abroad (national concept). The basket for calculating consumer price indices contains 711 representative products. The basket comprises the goods and services whose share in the total consumption of the households exceeds 0.1% and whose changes of prices best reflect the changes of prices or related products.

These attributes describe the as-reported time series, which we may enhance; we may also construct supplements.

Data on prices for representative goods and services are collected monthly by price collectors in Koper, Ljubljana, Maribor and Novo mesto in about 1,450 selected shops, marketplaces, at craftsmen and in other organisations. Some prices are also collected in other places in Slovenia, mostly by phone and via the Internet. On average about 18,000 prices are used for calculating the index every month.

Definitions

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 Slovenia (domestic concept).

Weighting has been based on the data from National Accounts on the structure of household final consumption expenditure. These data are also supplemented and verified with other statistical and non-statistical sources. Weights for 2016 are based on the data for 2014 recalculated to December 2015, which is also the price reference period.

It is the comparable index of consumer prices produced by each EU Member State and used for international comparison of consumer price inflation. Slovenia has been calculating it since 2001.

ECOICOP/HICP (Classification of Individual Consumption by Purpose / Harmonised Index of Consumer Prices) is a classification of products by purpose into 12 main groups, adapted to the needs of the harmonised index of consumer prices. The classification has been updated from COICOP/HICP as of January 2017.

Weights are shares of consumption of individual goods or services in the total consumption and are intended for measuring the impact of the change in the price of individual goods or services in the total change of the price.

Weight reference (base) period is the period, usually the selected year, to which the estimated values of consumption, used for calculating weights, refer.

Price reference (base) period is the period, the prices of which are in the index calculation compared to the prices of the current period. In our case the price base period is December of the previous year (since 1994).

Index reference (base) period is the period, usually the selected year, in which the index base is set to 100.

Non-durable goods are products with very short durability, usually up to one year (e.g. food).

Semi-durable goods are products with durability of about one year. They must not be very valuable (e.g. clothing and footwear).

Durable goods are products with long durability. At the same time they can be quite valuable (e.g. furniture, means of transport).

Seasonal products are goods and services that are available for purchase in some period of the year but are not available for purchase, or purchased in small or negligible volumes, for certain periods in a typical annual cyclical pattern. Before 2011, seasonal products in our case were fruit, vegetables and fishes.

In January 2011 we introduced changes in monitoring the prices of seasonal products. The methodology for monitoring the prices of seasonal products and calculating their indices was brought into line with the Regulation concerning minimum standards for the treatment of seasonal products in the Harmonized Indices of Consumer Prices, which came into force in January 2011. From January 2011 on seasonal products in our case include the following subgroups of goods and services; fresh fruit, fresh vegetables, women's clothing, footwear, household appliances, sports equipment and recreational services.

Fuels and energy is one of the special groups, which is composite from items for heating and lightning (045 Electricity, gas and other fuels) and motor fuels (0722 Fuels and lubricants).

Moody's Analytics supplements

For the all-items index we back-extend (1991m12 to 1999m12). For the all-items index and and "actual rent payments made," we construct SA counterparts using the X-13ARIMA-SEATS program.
