3 Statistical presentation

Description of statistical information (main characteristics, purpose)

The purpose is to determine the overall change in service producer prices during a certain period. Price indices are necessary for calculating macroeconomic indicators at comparable prices, analysing inflation processes in the service sector, production of forecasts.


Classifications(s), classification system

National version (EVRK Rev. 2) of the Statistical Classification of Economic Activities in the European Community (NACE);

Statistical Classification of Products by Activity in the European Economic Community (CPA2.1)

3.3 Sector coverage

Economic activities listed in sections H, J, L, M and N (transportation and storage, information and communication, real estate activities, professional, scientific and technical activities, administrative and support service activities) of NACE Rev. 2.

3.4 Statistical concepts and definitions

Service producer price index (SPPI) is a relative indicator reflecting the overall change in prices for services provided for economic entities over a certain period of time.

Price index is a relative indicator showing the price change over a certain period of time.

Index reference period is the reference period with the index equated to 100 points. Having the time series of price indices calculated with a single index reference period, it is possible to determine the SPPI for different periods.

Price reference period is a reference period based on the price level in which the overall change in prices is measured.
Weight reference period is the reference period the data of which are used for calculating index weights.

Weight is the volume of services of a certain level of classification in value terms, compared to the volume of services of a higher level in value terms during the reference period. The higher the weight, the stronger the effect of change in prices for services of a certain classification level on the change in prices for services of the higher classification level.

12 Quality management
12.1 Quality assurance

The quality of statistical information and its production process is ensured by the provisions of the European Statistics Code of Practice and ESS Quality Assurance Framework

In 2007, a quality management system, conforming to the requirements of the international quality management system standard ISO 9001, was introduced at Statistics Lithuania. The main trends in activity of Statistics Lithuania aimed at quality management and continuous development in the institution are established in the Quality Policy. Monitoring of the quality indicators of statistical processes and their results and self-evaluation of statistical survey managers is regularly carried out in order to identify the areas which need improvement and to promptly eliminate the shortcomings.

12.2 Quality assessment

Data quality corresponds to accuracy, timeliness and punctuality, comparability and compatibility requirements. Statistical survey managers periodically perform self-assessment – to evaluate statistical survey processes; moreover, statistical questionnaire control testing is performed.

13 Relevance
13.1 User needs

The main users of statistical information are the Bank of Lithuania, Eurostat, state institutions and agencies, international organisations, the media, business and research communities, students, whose needs are satisfied without a breach of the confidentiality principle.

13.2 User satisfaction

From 2005, user opinion surveys have been conducted on a regular basis. Official Statistics Portal traffic is monitored, website visitor opinion polls, general opinion poll on the products and services of Statistics Lithuania, target user group opinion polls and other surveys are conducted. In 2007, the compilation of a user satisfaction index was launched. The said surveys are aimed at the assessment of the overall demand for and necessity of statistical information in general and specific statistical indicators in particular.

More information on user surveys and their results is available in section User surveys on the Statistics Lithuania website.


Completeness of statistical information

SPPIs are published according to NACE Rev. 2 sections, at the 2-digit level.


Data completeness - rate

100 per cent of information produced in accordance with the Official statistics programme Part I is published.

14 Accuracy and reliability
14.1 Overall accuracy

– A purposive sampling method is applied to the selection of legal units, service groups and representative services. Statistical data on the annual income of legal units providing services for the previous years are used in order that the income of the legal units selected for a statistical survey on service prices would make up not less than 90 per cent of total income of legal units in the respective economic activity. After the legal units sampled have been questioned, the income of the legal units which have responded should make up not less than 70–80 per cent of the total income in the respective economic activity.
– SPPI time series are calculated based on the 2010 index reference period and are accurate to ten decimal places. The results are rounded to four decimal places and published in the Database of Indicators (on the Official Statistics Portal) and provided for Eurostat. Quarterly, annual, average annual and other price changes are calculated using SPPI time series accurate to all decimal places and published rounded to one decimal place.

16 Coherence and comparability

Geographical comparability

SPPIs by economic activity according to NACE Rev. 2 are comparable across the EU.


Comparability over time

Comparability is ensured.


Length of comparable time series

SPPIs are compiled since I quarter 2007.

For activity 51 (Air transport), SPPIs are compiled since I quarter 2010, for activity 52.29 (Other transportation support activities) - since I quarter 2011, for activity 58 (publishing activities) and real estate activities services (68) – since I quarter 2017, for activity 77 (rental and leasing activities) - since I quarter 2018.

17 Coherence

Cross-domain coherence


Internal coherence

Internal coherence is ensured. Lower-level price indices are aggregated to higher-level indices according to the Laspeyres formula, using base weights. Each higher-level price index is calculated as a weighted arithmetic mean of lower-level price indices.


Response burden

In 2016, the average time spent by a respondent on the filling in of statistical questionnaire KA-03 – 1 hr 30 min., KA-04 – 28 min.


Data revision

20 Statistical processing

Statistical data source

The main statistical data source – service producer price statistical survey (statistical questionnaire KA-04). The main source for weights – sample of representative producer services (statistical annual questionnaire KA-03). 


Periodicity of statistical data collection



Statistical data collection

Statistical data are collected through annual (KA-03) and quarterly (KA-04) statistical questionnaires.

Reporting forms: electronic statistical data preparation and transfer system e. Statistika, by fax, email, phone.


Statistical data validation

The specialists of data preparation divisions carry out the primary verification of the data received. The Price Statistics Division carries out the secondary verification and editing as well as validation of the data using a statistical price data control program. Data are compared to the data of previous periods. Reasons of changes (when changes are - +10 per cent - –10 per cent) in the prices of cost items are analysed. Particular attention is paid to quality changes, prices that do not change for a very long time, the lowest and the highest prices. Price trends are also checked against those in producer prices.

20.5 Data compilation

The SPPI is a Laspeyres-type price index. SPPIs are calculated from the lowest level, i.e. representative services, to the highest desirable level – by NACE class, group or division.

20.6 Adjustment

Statistical data are adjusted if the quality of the new (replacing) representative service considerably differs from that of the former (replaced) one; in such case, the impact of the change in quality on the price change is estimated. To maintain compatibility between the price of the replacing and the replaced product, service quality has to be adjusted: the price of the replaced product in the base period is adjusted by eliminating the impact of the change in quality. Methods applied: bridged overlap; overlap; expert estimation.
