In 2007, a quality management system, conforming to the requirements of the international quality management system standard ISO 9001, was introduced at Statistics Lithuania. 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 areas which need improvement and to promptly eliminate shortcomings.

More information on assurance of quality of statistical information and its preparation is published in the Quality Management section on the Statistics Lithuania website.

Quality of statistical results meets the requirements of accuracy, timeliness and punctuality, comparability and consistency.

According to the annually updated measurement plan of performance quality indicators of Statistics Lithuania, results of quality indicators of air transport statistical surveys monitored are presented in fields 14–17 of this metadata description. In 2017, a self-assessment of the head of the Air Transport Statistical Survey was carried out. It showed that the research results meet the requirements for the quality of statistical information. In 2017, the revision of the statistical form TOU-01 of aircraft, passenger and cargo flows at airports was carried out, the received recommendations were implemented.

When evaluating statistical indicators, quality of the obtained information is analyzed. Results of the calculation are compared with the results of the previous period and the previous year. Outstanding values of indicators are identified and analyzed. In the event of significant deviations, a data provider shall be contacted and the reasons for the deviation explained.

The main users of statistical information are State and municipal authorities and agencies, international organisations, the media, research and business communities, students, whose needs are satisfied without a breach of the confidentiality principle. Statistical information is used in forecasting and analyzing economic development.
