Reference metadata describe statistical concepts and methodologies used for the collection and generation of data. They provide information on data quality and, since they are strongly content-oriented, assist users in interpreting the data. Reference metadata, unlike structural metadata, can be decoupled from the data.

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.
11.2. Quality management - assessment
The system for measurement and monitoring of performance quality implemented at Statistics Lithuania allows making expeditious decisions, based on impartial information, which are important for the improvement of performance, detection and elimination of drawbacks.
Statistics Lithuania uses the following tools for quality monitoring and assurance:
- Monitoring of performance indicators (comprising ESS quality indicators, the response burden and indicators related to time used for different statistical processes),
- Self-assessment of survey managers (based on DESAP (European checklists for survey managers)),
- Statistical audits,
- Testing of previously approved statistical questionnaires.
Collecting information is submitted to the quality requirements, consistent with the standard quality components of European Statistical System, namely: relevance, accuracy, timeliness and punctuality, accessibility, clarity, comparability, coherence.
12.1. Relevance - User Needs
The main users of statistical information are State and municipal authorities and agencies, Eurostat, international organisations, the media, research and business community, students, whose needs are satisfied without a breach of the confidentiality principle. The index of number of persons employed is used for analytical, planning, forecasting, market research purposes.
12.2. Relevance - User Satisfaction
Since 2005, user opinion surveys have been conducted on a regular basis. The Official Statistics Portal traffic is monitored, website visitor opinion polls, general opinion poll on the products and services of the State Data Agency, 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 opinion surveys and results thereof are published in the User Surveys section on the State Data Agency website.
12.3. Completeness
All STS indicators are compiled and published to the extent defined in the legislation governing their compilation and publication. More detailed statistics are compiled according to individual user requests.
13.1. Accuracy - overall
The survey is carried out by sampling method. The sampling plan is compiled on the basis of the information of the Statistical Register of Economic Entities on the type of economic activity of the enterprise, the number of employed persons and the annual turnover. Enterprises are stratified by type of activity and number of persons employed. Non-response rate is low. Data are revised by collecting data for all periods of the reporting year (new information is received - data from administrative sources, respondents revise the reports submitted). Data processing errors are avoided by analyzing primary information when communicating with respondents. The coefficient of variation (CV) is used to evaluate the accuracy of the results.
13.2. Sampling error
Population is divided into 4 strata: enterprises with Value Added Tax payers, enterprises with no Value Added Tax payers, enterprises with high turnover of the reference year, estimation domain which have less than 3 enterprises. For the first two strata probability sample is used. Two another strata – completely enumerated.

13.3. Non-sampling error
Non-sampling errors do not significantly affect the results. Some cases of little scope appear due to data changes or appearance of the new enterprises in the Statistical Register of Economic Entities (when the enterprise is significant and has 50 and more employees data is recalculated at the end of the year). There are not many cases of non-receipt of data from respondents, therefore the non-response rate is low and did not exceed 2.3% in 2024.
Estimates of errors not related to the sample are negligible. Under-coverage, over-coverage impact is insignificant, we cannot evaluate exactly. In the case of a large enterprise, it is included in the sample with a weight 1.
14.1. Timeliness
Statistical information is published on the 60th day after the end of the reference month.
The rate of data publications at SL and transmissions to Eurostat on time is equal to 100 per cent.
15.1. Comparability - geographical
Statistical information is comparable between EU countries.
15.2. Comparability - over time
Data for some activities are available from January 2015. The HTNXK time series is comparable from January 2021.
15.3. Coherence - cross domain
The statistical information (change rates) of sales of service enterprises is comparable with the structural business survey data. Differences may occur due to different statsistical units.
15.4. Coherence - internal
The values of the indicators are internally coherent. The aggregated values of the indicators are derived from lower-level values in accordance with an established procedure. The full coherence of monthly, quartely and annual indicators of service enterprises is ensured.
The cost is determined for statistical survey in total and it is not possible to calculate for separate indicators.
In 2024 total cost (NSI) 17 963 hours per year for all variables of STS on services - turnover, persons employed, hours worked, wages and salaries.
Total burden (respondents) 20 9496 hours per year.
The same revision policy is applied for the data released nationally and transmitted to Eurostat.
Long-term planned (major) revisions are conducted after amendments in legal acts, due to changes in the base year, methodology and classifications entail revisions.
17.2. Data revision - practice
There are two main reasons why The Index of services production is being revised:
1) Revision of sales income (turnover) in services. When publishing data for the 12th month of the reporting year, the sales income for all periods of the two previous years are revised. Previous-year income declarations from natural persons engaged in individual economic activities or working with business certificates are obtained from the State Tax Inspectorate (STI). Data are sorted according to NACE Rev. 2. activities, and are included in the final statistical information of that year, and become the basis for the forecast of income of natural persons of the previous and current year;
2) Gap of Service producer price indices (SSPI) that are quarterly.
Changes in The Index of services production revisions (Mean revision (MR), Mean Absolute Revision (MAR)) will be monitored and calculated from next year when the HTNXK time serie will be sufficient.

18.1. Source data
Main statistical data source - a monthly statistical sample survey on the activities of service enterprises (sample – 4 430 respondents, i.e. 12,4 per cent of all economic entities). Statistical indicators of accommodation activity (division I55) are evaluated using statistical data of the survey of accommodation services (census survey, 422 respondens). Statistical indicators of food and beverage activities (division I56) are evaluated using statistical data of the monthly statistical sample survey of trade and catering enterprises (sample – 487 respondents, i.e. 14,8 per cent of all economic entities).
The Index of services production is based on deflated index of service turnover. Different price indices are used in calculating the index: Service producer price indices (SSPI), Consumer price indices (CPI).

Monthly
18.3. Data collection
The data are collected using the Business Services Enterprise Activity Statistical Questionnaire (PS-20) via the Internet, through the Electronic Statistical Business Data Preparation and Transmission System e.Statistics.
18.4. Data validation
To ensure the quality of statistical data, statistical data analysis, data verification and validation, editing and recording of missing values at the level of statistical data arrays are performed. Statistics are checked as they are entered and processed. Arithmetic, logical and compatibility statistics control, comparison of data with the data of the previous period and the corresponding period of the previous year is provided. Statistics are corrected taking into account the type of error: mandatory and ignored (warnings to respondents about possible errors). Reminders are sent to respondents who have not provided statistics, reasons for non-reporting are clarified.
18.5. Data compilation
The Index of services production consists of a number of indices calculated as monthly Turnover index at current prices (from monthly statistical sample survey on the activities of service enterprises) / monthly Index on Price (from SSPI, CPI).
n order to eliminate the influence of season and/or the number of working days, seasonal adjustment of the indicator time series is performed using the TRAMO / SEATS method, JDemetra + (version 2.2.2) Program. The seasonal adjustment model for the time series of the statistical indicator shall be established for one year and updated once a year, with all periods for the reference year. The horizon revision covers 4 years: the current year and 3 years backwards. Seasonal and calendar factors are used in the modelling, regressors of working/non-working days, lifting years are used; exceptions are identified and adjusted; the calendar of Lithuanian public holidays is taken into account. Statistical significance of the variables, number of exclusions, statistical characteristics of the residues (seasonality of the residues, independence, normality, etc.) are checked during validation. Seasonal adjustment and balancing is performed following recommendations laid down in “Handbook on Seasonal Adjusment (2018)“.
The Index of services production is a business cycle indicator which measures the monthly changes of the price adjusted output of the services industries.
