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. 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. 

After the defined the resident population number by the Population and Housing Census of the Republic of Lithuania, it is compared with estimated resident population number, and if it is the big difference - revised. Population and its composition is also revised in inter-census period. 

The data about children under 1-year visits to the medical doctor from Compulsory Health Insurance Information System (Sveidra) under the National Health Insurance Fund under the Ministry of Health is used for the improving of the estimation of the number of live births. In the number of live births are included only those children born abroad who visited to the medical doctor at least once during the year after birth. Number of live births is compared with the final results of the Population and Housing Census of the Republic of Lithuania, in case of discrepancy number of live births is recalculated. 

After processing the annual mortality data, analysis is performed. Mortality data by permanent place of residence produced by Statistics Lithuania are compared with causes of death data produced by Institute of Hygiene. In case of discrepancies, checks of source data are performed, taking in account the changes of permanent place of residence in the Population Register. 

 Monthly (provisional) statistical data are processed according to declaration of change of place of residence (from Lithuania to foreign country, from foreign country to Lithuania) and following the statistical rules, by merging databases of international migration of demographic statistics and the Population and Housing Census 2011, considering whether an international migrant is included in the database of the Population and Housing Census 2011 and taking into account the international migration history of person. 

Annual (final) statistical data are based on monthly (provisional) data and taking into account that: 

• immigrant who has declared his or her arrival is attributed to annual immigrants if by the end of the reference year he or she has not declared the departure from Lithuania; 
• emigrant who has declared his or her departure is attributed to annual emigrants if by the end of the reference year he or she has not declared the return to Lithuania. 

The results are compared with the results of previous year. If there are significant deviations, reasons for deviations are considered. 

The number of emigrants was revised after the Population and Housing Census of the Republic of Lithuania. The number of emigrants by various breakdowns was also revised in inter-census period.
