Data on long-term migration provide information on the number of persons arriving to the country for permanent residence or for at least one year, the number of persons departing from the country for permanent residence or for at least one year, as well as data on internal long-term migration.

A long-term emigrant is a person departing to another country (international emigrant) or other administrative territory of Latvia for permanent residence or at least for one year.

A long-term immigrant is a person arriving from another country (international immigrant) or another administrative territory of Latvia for permanent residence or at least for one year.

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.
 

Net migration is the difference between the total number of persons arriving in a definite administrative territory for permanent residence and the total number of persons departing from their permanent place of residence during a set period of time.

Classifications

Data on long-term migration are collected and published in compliance with following classifications:

  • Classification of Administrative Territories and Territorial Units of the Republic of Latvia (CATTU);
  • Classification of Ethnicities;

Data collection

Survey method and source data

International long-term migration flows were estimated in 2011 and 2012 by using the statistics of other countries on immigrants from Latvia (mirror statistics), trends in registered migration, as well as the information on migration compiled from the Population and Housing Census 2011.

In order to prepare population statistics, a methodology based on statistical classification was developed in 2012. The model was created by using logistic regression analysis. International long-term migration flows were estimated by using the respective model.

By breaking down the population into all of the administrative territories of the country, the actual place of residence of persons indicated in the census was taken into account.

Long-term migration of the population for the period from 2000 to 2010 has been recalculated by taking into account the information on non-registered emigration compiled from the Population and Housing Census 2011.

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

Emigration estimates were 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. The 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.

Since the Population Register and Population and Housing Census 2011 provides information on an emigrant’s gender, birth year, emigration year and emigration times, while administrative sources on estimated emigration give information only on the birth year and gender, in order 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 on each emigrant’s emigration year registered in the Population Register and the Population and Housing Census 2011, as well as the total amount of emigrations of  allemigrants during the time period from 2000 to 2010 that have been calculated with the help of the following 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 an emigrant was identified in both the Population Register and the Population and Housing Census 2011, a decision was made to use the emigration year mentioned in the Population and Housing Census 2011.

Data revision

Short-term (quarterly and monthly) statistical data are revised after processing of annual statistical information. Short-term migration statistics is revised also after processing of quarterly statistical data.
