The objective of the indicator - index of hours worked by employees -  to approximate the development of hours worked by employees in the enterprises of INDUSTRY, CONSTRUCTION, TRADE and SERVICES.

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

Hours worked by employees is the total number of hours worked by employees during the reference quarter. This covers all hours worked including overtime, night work, working on weekends and public holidays; time spent on preparation for work, short rest periods; time spent at the place of work during which no work is done (due to technical obstacles) but for which payment is made in accordance with legislation or collective agreement. Hours paid but not worked (such as sickness, strike, annual leave) are excluded.

Index of hours worked by employees is a relative indicator showing the change in the time worked during the reference quarter.

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.

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.

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. 

Since 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 opinion surveys and results thereof are published in the User Surveys section on the Statistics Lithuania website.

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 (only in Lithuanian).

Frame population is carried our from the Statistical Business Register (SBR). To define frame population main variables are: economic activity, number of persons employed and turnover of enterprises. Sampling design – simple random stratified sample. Strata are conducted according to the kind of activity and the number of persons employed. Non response rate is low (data can be submitted electronically). Impact of measurement and processing errors is eliminated by finding outliers, contacting with the reporting units, using editing procedures to the raw data, analysis. The overall accuracy is high. The measure of the estimates – coefficient of variation.

The coefficient of variation is calculated on the value of hors worked by employees each quarter:

Estimates of errors not related to the sample are negligible.

Statistical information for INDUSTRY, TRADE, SERVICES is published  on the 90th day,  for CONSTRUCTION - on the 60th day after the end of the reporting quarter as well as sent to Eurostat.

Statistical information is published in accordance with Official Statistics Calendar, also is sent to Eurostat according with the approved Release Calendar.

The rate of data publications at SL and transmissions to Eurostat on time is equal to 100 per cent.

Statistical information is comparable between EU countries.

INDUSTRY, CONSTRUCTION

Quarterly time series are comparable since first quarter of 1998.

TRADE, SERVICES

Quarterly time series are comparable since first quarter of 2010.

The data are comparable with Labour statistics.

The values of the  indicators are internally coherent. The aggregated values of indicators are derived from lower-level values in accordance with an established procedure.

The cost is determined for statistical survey in total and it is not possible to calculate for separate indicators.

INDUSTRY

Total cost 13 750 hours per year. Total burden (respondents) 19 184 hours per year.

CONSTRUCTION

Costs 4 880 hours per year. Total burden (respondents) 5 894 hours per year.

TRADE

Costs 16 545 hours per year. Total burden (respondents) 20 395 hours per year.

SERVICES

Costs 8 229 hours per year. Total burden (respondents) 7 914 hours per year.

Revisions of statistical indicators are performed in accordance with the General Principles behind the Performance, Analysis and Announcement of Revisions of Statistical Indicators. Users are informed about scheduled revisions in advance through a Calendar of Scheduled Revisions of Statistical Indicators.

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. The time series from first quarter 1998 (INDUSTRY, CONSTRUCTION) or first quarter 2010 (TRADE, SERVICES) are back-casted.

After amendments in legal acts, changes of the base year and classifications, detection of significant errors, revisions of statistical indicators are performed. Users are informed about the results and changes.

Data source of statistical information on variable hours worked is monthly or quartely surveys in each sector.

INDUSTRY

Questionnaire for sections B and C: Monthly statistical report on industrial enterprises P-11.

Questionnaires for sections D and E: Monthly natural gas supply questionnaire PD-11, Monthly electrical energy generation questionnaire PEG-11, Monthly electrical energy transmission questionnaire PEP-11, Monthly electrical energy distribution and supply questionnaire PET-11, Monthly heat generation and distribution questionnaire PŠ-11, Monthly water collection and distribution questionnaire PV-11.

SERVICES

Quartely statistical questionnaire on business services (PS-20). Statistical indicators of accommodation activity (Division I55) are evaluated using statistical data of the survey of accommodation services.

Quarterly variable in the monthly questionnaires for enterprices of INDUSTRY, CONSTRUCTION, TRADE and quartely questionnaire for enterprises of SERVICE.

Statistical data are collected through an electronic statistical data preparation and transfer system e-Statistics.

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.

 The estimates are computed using regular stratified random sampling formulae (ratio estimator). The index is calculated in comparison with the quarterly average of 2021 (base year). The process of the preparation of statistical information is described in the surveys methodologies (only in Lituanian):

Industrial enterprise activity statistical survey methodology

Construction enterprises activity statistical survey methodology

Monthly statistical survey on trade and catering enterprises methodology 

Methodology of the statistical survey on the activities of service enterprises

The time series of hours worked by employees are calendar day adjusted, using the TRAMO/SEATS method in JDemetra + (version 2.2.2). A direct method is used for this adjustment.

The model is chosen using a detailed analysis module. The logarythm of transformation is tested. Calendar factors are estimateds, 2 regressors (working days) and national holiday's calendar are used, leap year is adjusted. Reg/ARIMA is used for calendar adjustment.

The significance levels, the number of outliers and statistics on residuals (residual normality, residual assimetry, etc.) are controlled in the data series.

Calendar adjustment models and parameters are fixed for one year and revised once a year when the data of all reporting quarters is available. The horizon revision covers 4 years: the currenr year and 3 years backwards.

Alignment is performed using the manual Handbook on Seasonal Adjustment (2018).
