Information on the number of population and key demographic indicators provide data on population number by various demographic characteristics and key demographic indicators – number of marriages and divorces, number of births and deaths etc.

For the production of population statistics, a methodology based on statistical classification was elaborated in 2012. The statistical classification divides the number of population registered in Latvia into two classes (groups): those actually living in Latvia (usually resident population of Latvia), and those actually living abroad. The model of statistical classification has been developed applying the logic regression analysis.

In order to estimate the number of population, the CSB uses data of the administrative registry:

  • Data of the Office of Citizenship and Migration Affairs (OCMA);
  • State Revenue Service (SRS) data;
  • State Social Insurance Agency (SSIA) data;
  • Ministry of Education and Science (MES) data;
  • Agricultural Data Centre (ADC) data;
  • Rural Support Service (RSS) data;
  • National Health Service (NHS) data;
  • State Employment Agency (SEA) data;
  • Data on students provided by the 30 largest higher education institutions in Latvia;
  • Data of the Road Traffic Safety Directorate;
  • Data of the Social Aid Administration Application (SOPA);
  • Data of the Latvian Prison Administration. 

The CSB believes that additional individual data that may be used as a base for developing explanatory variables allowing to improve precision of the model developed and being suitable for the quality control of the estimates might include the following:

  • individual data available to Latvian libraries about persons who have used library services;
  • individual data of the Administration of Studies and Research about persons who have received a study/ student loan for studies abroad;
  • data of the Ministry of Education and Science about children at school age who have not been registered with any of the educational institutions;
  • individual data of the Riga municipal limited liability company “Rīgas satiksme” about personalised e-tickets;
  • persons who have participated in the largest household surveys.

Determination of the actual place of residence in Latvia

In the third quarter of 2016, during the carrying out of the project "Acquisition of territorial statistics (mainly urban)", the existing algorithm for calculation of the territorial disposition of population – the actual place of residence – was revised. Algorithm was updated, ensuring more accurate population estimation in parishes, counties, cities and regions. At the beginning of 2016, recalculation of the indicators was carried out according to the new algorithm. Consequently, the indicators in certain parishes, counties, cities and regions are not comparable with the ones of the previous years.

For determination of the residence of the usual residents in Latvia, the actual place of residence specified in the 2011 Census and the changes in the residence after 1 March 2011, according to the information in the Population Register is taken into account:

  • if the person's declared residence has not changed after the census, the residence is determined according to the actual residence specified in the census on 1 March 2011;
  • if the person's declared residence has been changed after the Census, or if the person has not participated in the Census, the residence is determined according to the declared residence in the Population Register on 1 January 2016.

In the previously used algorithm, the changes in the declared residence were determined by comparing a person's residence – administrative territories or territorial units of municipalities – on 1 March 2011 and on 1 January 2016.

The changes of the declared residence in the extended algorithm are determined, taking into account the reasons and the date of the changes of the residence specified in the registry of OCMA. The usual residence is changed, if records of the changes of the residence of the person are entered in the OCMA databases after 1 March 2011 (for example, the residence is declared, information on the residence is specified orally).

This allows to specify changes more accurately of residence of the person within Latvia, including the cases when the person changes their residence within one administrative territory or territorial unit of municipality, or returns to the previous residence after a stay in another administrative territory or territorial unit of municipality.

The actual residence of certain groups of the population are determined as follows:

  • for persons in prison – the place of detention is determined to be the actual residence;
  • for persons in social care institutions – the social care institution is determined to be the actual place of residence. Starting with 01.01.2016, the usual residence of the persons, who have received pensions or allowances according to the SSIA data and reside in social care institutions, have been clarified. According to Article 2 of the Regulation of the European Parliament and of the Council on European demographic statistics (5) the usual residence of these persons is the respective social care institution. Comparing the information of 2011 Census with the data in the Population Register at the moment of Census, 73 % of the persons in the social care institution had declared it as their residence. So, starting with 01.01.2016, using the individual data on persons provided by SSIA for persons in social care institutions – the social care institution is determined to be their actual residence.

In 2016, more detailed analysis of the declared places of residence of Latvia population was performed by geo-referencing and visualising the respective data cartographically. The analysis allowed detecting places with large number of persons having declared their place of residence at the workplace thereof, therefore the method used to project usually resident population was improved, and, in line with the internationally adopted definition, the number of persons having declared their place of usual residence at their workplace (enterprise registered in Latvia) but being foreigners and not living in Latvia actually (e.g., lorry drivers, who are guest workers from other countries) was excluded from the number of usually resident population. The changes were introduced starting from the data on 2017.

Due to the mentioned reason the population change, e.g., in Mārupe county indicates an increase of 5 % in 2015, whereas in 2016 a decline of 0.5 %. The actual population increase in 2015 and 2016 constitutes 2–3 %. Similar situation may be observed in Riga and Carnikava county, however population change in these regions is smaller.

Usually resident population by declared place of residence

In 2017, CSB will be publishing population number estimates* not only in the breakdown by region, county and city under state jurisdiction based on the actual place of residence detected by the CSB, but also based on the declared place of residence in line with the information of the Population Register of the Office of Citizenship and Migration Affairs. Such an approach was chosen because starting from 2021 the demography statistics will be estimated solely based on the CSB population number estimate made in line with the declared place of residence. The declared place of residence will be revised only in exceptional cases (for persons in social care institutions and places of imprisonment, as well as for children that in line with the Population Register information are the only persons declared in the respective residence).

 

 

Definitions

State significance national and regional development centres have been identified in the sustainable development strategy of Latvia until 2030 (Latvia 2030). According to Latvia 2030 strategy, regional development centre category includes 21 cities: Aizkraukle, Alūksne, Balvi, Bauska, Cēsis, Dobele, Gulbene, Krāslava, Kuldīga, Limbaži, Līvāni, Ludza, Madona, Ogre, Preiļi, Saldus, Sigulda, Smiltene, Talsi, Tukums and Valka.

The average population during a calendar year is generally calculated as the arithmetic mean of the population on January 1 in two consecutive years (it is also referred to as the mean population).

Demographic burden is the ratio of the number of persons under working age and over working age per 1000 people of working age.

Demographic burden indicators have been calculated since 1990. Over time, the main age groups of the population have changed, and different age has been used for men and women. More details:

A marriage is regarded as divorced if the court ruling has become legally effective.

Since 1 February 2011 marriage in Latvia may be divorced also by a sworn notary.

Long-term migration implies movement of the population from one administrative territory to another with an aim to change the place of residence permanently or for a period of at least one year.

Migration is divided into external (international) migration and internal (within the territory of Latvia) migration.

Data on migration in breakdown by city and county also include internal migration between various administrative territories. However, if a person changes the place of residence within the boundaries of a town or county, the migratory movements of such a person are not counted, according to the recommendations of international organisations.

The population long-term migration during the time period from 2000 to 2010 has been recalculated on the basis of information on non-registered emigration compiled within the Population and Housing Census 2011.
 

The main age groups of usually resident population: under working age, of working age and over working age – are defined in compliance with the working age and retirement age set by the legislation of the respective years. 

The working age used in the age structure calculations since 1 January 2017 is assumed to be 15–62 years, under working age – 0–14 years, and over working age – 63 years and more.

Individual status of a person in relation to the family according to the national legislation.

Four standard categories are used: single (unmarried), married, divorced, and widowed.

In vital statistics population is classified by the marital status on the basis of the data of the Office of Citizenship and Migration Affairs.

Natural increase is the difference between the number of births and the number of deaths in a given period of time.

Number of births registered in the Republic of Latvia during a year, if at least one of the parents is a permanent resident of the Republic of Latvia.

Starting from 2000 the number of births has been recalculated including also children born outside Latvia to mother (permanent resident of Latvia) temporarily being abroad. In compliance with the methodology of the Statistical Office of the European Union (Eurostat) these children should also be included in the number of children born in Latvia. 

Number of deaths registered in the Republic of Latvia during a year.

This number is not specified, if person in a longer time period is declared to be dead.

Place in which person usually spends the rest period of the day, not considering short-term absence for entertainment, vocation, visit to friends or relatives, business, medical treatment or pilgrimage.

Breakdown of the population by urban and rural inhabitants is made according to their permanent place of residence. Urban population refers to those persons who live in cities and towns, i.e., in populated areas with at least 2 000 usually resident population. In a number of historically developed cities, the population may be less than 2 000.

Status of a city and town is assigned and cancelled by the Saeima with law. 

All the rest is considered rural population. 

Usually resident population – all inhabitants whose permanent place of residence is the respective administrative territory.

The following persons shall be considered to be usual residents of the respective administrative territory: those who have lived in their place of usual residence for at least 12 consecutive months before January 1 of the respective year, as well as those who arrived in their place of usual residence with the intention of staying there for at least one year.

Number of population from 1 January 2001 to 1 January 2011 has been re-calculated according to the results of Population and Housing Census 2011, taking into account non-registered emigration.

Starting with 1 January 2012 the number of population is determined according to new methodology, using logistic regression model. Data from more than 40 different national administrative registers were used in the model.

Additional information

Data on population number are shown (if not specified otherwise) within the current boundaries of Latvia in accordance with the Central Statistical Bureau calculations at the beginning of the year. In years when Population and Housing Census was conducted – 12 February 1935, 15 January 1959 and 1970, 17 January 1979, 12 January 1989 and 31 March 2000 – population number on the data of the Census is given. Data on population number and factors influencing it since Population and Housing Census 1989 are recalculated basing on results of the Population and Housing Census 2000. Population number from 2001 till the beginning of 2010 and long-term migration of population in 2000–2010 are recalculated basing on the results of the Population and Housing Census.

Recalculation of the population number on the time period 2001–2010 is based on the information on number of population on 1 January 2000, information on population number on 1 January 2011 that has been recalculated in compliance with the Population and Housing Census 2011 results, official information on natural movement and immigration during 10 years, as well as official information on emigrants acquired within the framework of the Population and Housing Census 2011. Population number on the time period 2001–2010 was recalculated in a way to achieve compliance among the number of population on 1 January 2000 and 1 January 2011, natural movement and migration during 10 years. Emigration estimates in breakdown by years during the time period 2000–2010 were changed significantly. Emigration estimates were based on the information on emigration year in emigrant data officially registered within the framework of the Population and Housing Census 2011. This information was extrapolated on all emigrants with the help of raking-ratio calibration method, achieving concordance with emigrant number in gender groups and number of emigration times in birth year and gender groups during the time period 2000–2010.

Population number in time period from 01.01.2001 till 01.01.2011 is recalculated in compliance with the results of the Population and Housing Census 2011, considering non-registered emigration. Moreover, breakdown of population by administrative territory is based on actual place of residence indicated by the person in Census.

Due to the recalculation of population number from 2001 till 2010, also the indicators calculated per 100, 1 000 or 10 000 population change.

Due to specifics of electronic data processing technologies and rounding adjustments, minor differences may occur between published indicators and data calculated by users.

Data collection

Survey method and data source

For the production of population statistics, a methodology based on statistical classification was elaborated in 2012. The statistical classification divides the number of population registered in Latvia into two classes (groups): those actually living in Latvia (usually resident population of Latvia), and those actually living abroad. The model of statistical classification has been developed applying the logic regression analysis.

The statistical classification model: data, model development, application, calculation formulas, model improvement can download here (pdf) (updated 28.06.2017)

Recalculation of population number and international migration for the time period 01.01.2000–01.01.2011

Emigration estimates are based on three data sources – emigration stated in the Population Register, emigration indicated in the results of the Population and Housing Census 2011 and estimated emigrants based on both administrative registers and Population and Housing Census 2011. With the help of this information the number of emigrants is acquired on the time period 2000–2010. Number of emigrants has been recalculated in a way to ensure that several demographic indicators in gender and birth year groups are harmonised in time, i.e.:

  • Birth number from 2000 till 2010;
  • Death number from 2000 till 2010;
  • Immigration from 2000 till 2010;
  • Population number at the beginning of 2000 and 2011.

As Population Register and Population and Housing Census 2011 provides information on emigrant’s gender, birth year, emigration year and emigration times, while administrative sources on estimated emigration give information only on birth year and gender, thus to estimate the total number of emigrants in breakdown by year a "raking ratio" calibration method is used1.

The calibration method is based on the data regarding each emigrant’s emigration year in Population Register and Population and Housing Census 2011 as well as total all emigrants’ number of emigrations during the time period from 2000 till 2010 that have been calculated with the help of equation

where

P2011 – population number at the beginning of 2011;

P2000 – population number at the beginning of 2000;

DZ2000-2010 – birth number from 2000 till 2010;

M2000-2010 – death number from 2000 till 2010;

IM2000-2010 – immigration from 2000 till 2010;

EM2000-2010 – emigration from 2000 till 2010.

As a result, weights in gender and birth year groups were calculated for each emigrant stated in the Population Register and Population and Housing Census 2011, and they were used to estimate the total emigrant number in breakdown by year.

It should be considered that in cases, when emigrant was stated in both Population Register and Population and Housing Census 2011, a decision was made to use the emigration year mentioned in the Population and Housing Census 2011.

Data revision

When publishing monthly population number, only registered population change is taken into account (both natural increase and net migration). In the 2nd quarter of the following year, the population number at the beginning of the year and in previous month is specified considering non-registered migration as well as fertility and mortality data in line with the actual month of the event.

Number of live births

The data on registered number of live births occurred during the corresponding month in the database short-term statistical data section are published in the last reference year. It means that statistics on the number of births includes part of the births occurred during the previous month, but not all births occurred during the respective month are included in the statistics, as in line with the Law On Registration of Civil Status Documents a child shall be registered within a month after the birth thereof. In June of the following year, the data on all live births occurred during the previous year are compiled and published based on the actual month of the birth. Starting from 2000, the number of births includes also children born to mother (usually resident of Latvia) while temporarily abroad. In line with Eurostat methodology, such children shall be included in the number of children born in Latvia.

Number of deaths

The data on registered number of deaths occurred during the corresponding month in the database short-term statistical data section are published in the last reference year. It means that statistics on the number of deaths includes part of the deaths occurred during the previous month, but not all deaths occurred during the respective month are included in the statistics,as in line with the Law On Registration of Civil Status Documents the death shall be registered within a six working days after it took place. In June of the following year, the data on all deaths occurred during the previous year are compiled and published based on the actual month of the death.

Number of marriages

The data on registered number of marriages concluded during the corresponding month in the database short-term statistical data section are published in the last reference year. It means that statistics on the number of marriages includes also part of marriages concluded by citizens of other countries (not usually residents of Latvia) and does not include marriages registered by clergies of the confessions provided for in the Civil Law. In June of the following year, the data on all marriages concluded during the previous year are compiled and published based on the actual month of the marriage, by supplementing marriage number also with the marriages concluded by citizens of other countries if one of the spouses is usually resident of Latvia.
