Data on consumer price indices, published in the First Release of 5 February 2021, are published at a more detailed level in the SiStat Database.



METHODOLOGICAL NOTE

Due to the second wave of the coronavirus epidemic, SURS is still faced with difficulties in data collection.

In January 2021, we collected retail prices of non-food goods and services to a greater extent by phone and through the websites of providers. Higher quality of the indices was ensured by using scanner data, as we continue to obtain them weekly.

Where prices could not be collected or services were not provided, data were compiled in accordance with Eurostat recommendations, so in some subgroups the published indices are less reliable than usual. The missing prices were imputed by using the price changes of similar products. In some cases, where there are reasons to expect that the prices will be the same once the situation will revert back to normal, the carry forward method was used. For series with seasonal patterns (package holidays and some accommodation services), imputation with monthly change of the previous year was used. The share of imputed data represents 6.7% of the total harmonised index of consumer prices and 8.6% of the total consumer price index. A detailed overview of the subgroups where the indices are less reliable and what method was used can be found here.


New developments and methodological changes in 2021

As in the previous years, weights were changed; they are now based on the average of expenditure from the 2018 Household Budget Survey recalculated to December 2020 prices. We also took into account major changes in HICP weights, which were made on the basis of estimated national accounts data on household expenditure for 2020.

The COVID-19 epidemic has a significant impact on household consumption expenditure. Weights for the harmonised index of consumer prices are compiled in accordance with Eurostat recommendations. They are based on the data for 2019 and estimated data from national accounts for 2020 and recalculated to the difference between the average of 2020 and December 2020, which is also the price reference period.

At the same time, we also updated the list of other goods and services and the outlets where prices are collected.
