3.1. Data description

Data and metadata are transmitted to Eurostat by the Member States in the framework of the Unified Demographic Data Collection which is in accordance with Regulation (EC) No 862/2007 and Regulation (EU) No 1260/2013 and their implementing regulations.

This Euro SDMX Metadata Structure is used for the purpose of quality reporting. The definition of the quality concepts and guidelines are described in the European Statistical System Handbook for Quality Reports.

The objective of the Determination of the Usually Resident Population and its Composition statistical survey is to produce and provide for users statistical information on the number of the resident population and its structure by sex, age, citizenship, country of birth, marital status, territorial-administrative units (Capital Region, Central and Western Lithuanian Region, county, municipality (in total, towns/cities, urban/rural areas)) and other indicators. The usually resident population and its structure are determined using a cohort-component method (based on the results of the most recent population and housing census, statistical data on live births, deaths, individuals changing their usual place of residence, territorial-administrative changes).

The objective of the Fertility Statistical Survey is to produce and provide for users statistical information on the number of live births by sex, country of birth, citizenship, birth order, territorial-administrative units (Capital Region, Central and Western Lithuanian Region, county, municipality (in total, towns/cities, urban/rural areas)), also statistical information about parents (age, country of birth, citizenship, legal marital status, duration of marriage, etc.), the number of deliveries and other indicators. The survey is a total survey. For the survey, data from birth records in the Population Register and other data from the register on the baby's and its parents' place of residence, as well as data from identity documents issued in the Republic of Lithuania (document type, date of issue and expiry), are used.

The objective of the Mortality Statistical Survey is to produce and provide for users statistical information on the number of deaths by sex, age, country of birth, citizenship, legal marital status, territorial-administrative units (Capital Region, Central and Western Lithuanian Region, county, municipality (in total, towns/cities, urban/rural areas)), as well as the number of stillbirths by sex, birth order, urban/rural areas, age of mother and other indicators. The survey is a total survey carried out on the basis of the Population Register data. The survey population is formed on the basis of data from records of births and deaths from the Population Register and data from identity documents issued in the Republic of Lithuania (document type, date of issue and expiry).

The objective of the International Migration Statistical Survey is to produce and provide for users statistical information on the number of immigrants and emigrants, their composition by sex, age, citizenship, country of birth, last or next place (country) of residence, marital status, territorial-administrative units (Capital Region, Central and Western Lithuanian Region, county, municipality (in total, towns/cities, urban/rural areas)) and other indicators. The survey is a total survey. The main data source of immigration and emigration indicators is the data from the Population Register. The population of the survey is compiled based on the following data from the Population Register: declared place of residence in the Republic of Lithuania, date of arrival, country of departure, date of departure, county of destination. The main criteria for defining immigrants and emigrants are the change of a country of the usual residence and duration of stay or absence in case of intention to take up usual residence in a new place (country) for good or for a period, not less than 12 months.

The objective of the Marriage Statistical Survey is to produce and provide for users statistical information on the number of marriages and married persons by sex, age, mean age at marriage, previous marital status, citizenship, marriages by age differences of the newlyweds, territorial-administrative units (Capital Region, Central and Western Lithuanian Region, county, municipality (in total, towns/cities, urban/rural areas)) and other indicators. The survey is a total survey carried out on the basis of the Population Register data. The survey population is formed on the basis of data from records of marriage from the Population Register and data from identity documents issued in the Republic of Lithuania (document type, date of issue and expiry).

The objective of the Divorce Statistical Survey is to produce and provide for user’s statistical information on the number of divorces and divorced persons by sex, age, a number of common children, duration of the marriage, citizenship, territorial-administrative units (Capital Region, Central, and Western Lithuanian Region, county, municipality (in total, towns/cities, urban/rural areas)) and other indicators. The survey is a total survey carried out on the basis of the Population Register data. The survey population is formed on the basis of data from records of divorce from the Population Register and data from identity documents issued in the Republic of Lithuania (document type, date of issue and expiry).

The objective of the Annual Survey of health care establishments is to produce and provide for users statistical information on the resources and activities of health care institutions, including the number of abortions by ICD-10 code, age of women, urban/rural inhabitants.

Acquisitions/loss of citizenship

Includes the list of any categories of persons, who have acquired citizenship during the reference year and who might have been excluded from the figures reported (e.g. adopted children, non-nationals married to citizens of the reporting country, only naturalizations reported, etc.). A person must swear an oath of allegiance to the Republic of Lithuania within 6 months for stateless persons, and 2 years for persons who have the citizenship of another state from the day of entry into force of the Decree of the President of the Republic, whereby a person is granted citizenship of the Republic of Lithuania. So, if the citizenship was granted during the reference year and the person took the oath to the Republic of Lithuania during the period of 6 months for stateless persons, and 2 years for persons who have the citizenship of another state, it might be that this person is excluded from the figures of the reporting year and is included into the next year’s statistics.

3.2. Classification system

The regional breakdown of the Member States in the regional demographic tables is done under the most recent NUTS classification. There are agreements between Eurostat and Candidate countries as well as between Eurostat and EFTA countries, for which statistical regions have been coded in a way that resembles NUTS.

For more information on the versions in force, please see: https://ec.europa.eu/eurostat/web/nuts/.

12. Relevance

Top

12.1. Relevance - User Needs

Main users of statistical information on demographic and migration statistics are State and municipal authorities and agencies, international organizations, the media, research and business communities, students, Eurostat, whose needs are satisfied without a breach of the confidentiality principle.

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 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.

For more information on user surveys and their results, see section User surveys on the Statistics Lithuania website.

12.3. Completeness

All indicators established by the legislation and their components are published.

13. Accuracy

Top

13.1. Accuracy - overall

	Overall accuracy and special cases (Inclusion/exclusion of asylum seekers and refugees, persons living on an unauthorized or irregular basis, international students, persons who do not register/deregister)
Population	Annual usually resident population estimates are based on the most recent census round applying the cohort-component method (census data is updated by annual data on live births, deaths, migration) and administrative-territorial changes. Persons who have been granted subsidiary or temporary protection or refugee status in the Republic of Lithuania are considered as usually resident population of the Republic of Lithuania. Asylum seekers usually do not stay in the Republic of Lithuania for more than 12 months and they are not considered as the usually resident population of the Republic of Lithuania. The main data source for statistical data on live births, deaths, and migration is the Population Register. The quality of the Population Register data is good.

The difference between IM (International Migration) and RP (Residence Permits) flow statistics:

The number of immigrants estimated by the State Data Agency (Statistics Lithuania) is based on the intention to change the usual residence for a period not shorter than a year.

If a birth has occurred for a third-country national that holds a temporary residence permit in the Republic of Lithuania, a temporary residence permit is also issued for a newborn, including it in RP statistics. However, this newborn is included in birth statistics, but not in the IM.

The difference between IM (International Migration) and RP (Residence Permits) stock statistics:

The number of immigrants estimated by the State Data Agency (Statistics Lithuania) is based on the intention to change the usual residence for a period not shorter than a year.

IM from the third-country nationals who hold temporary residence permits for 12 months or more, but have declared their departure from the Republic of Lithuania during the reference year, are not included in the total number of immigrants, but are included in RP statistics.

If a newborn of a third-country national that holds a temporary residence permit in the Republic of Lithuania emigrates during the reference year, he/she is included in the total number of emigrants.
