3.4. Statistical concepts and definitions | |||
Data on number of usual resident population at the end of the reference period (midnight of 31 December). Population and Housing Census 2011 resulted in specifying number of resident population of Latvia, and it notably – by 155 thousand or 7% – differed from the population number calculated in line with the information in Register of Natural Persons supervised by the Office of Citizenship and Migration Affairs. As European Union does not have common methodology for estimating population number, Central Statistical Bureau has worked out a new method for more precise estimation of population number in Latvia. The method is based on statistical classification and migration mirror statistics. Statistical classification aims at dividing Latvian population registered within the Register of Natural Persons of Latvia into two classes (groups) – persons actually living in Latvia (usual resident population of Latvia) and persons actually living abroad. The statistical classification model has been developed with the help of logistic regression analysis. Data from administrative data sources are used to determine the statuss. 12-month period is used for migration (actual). Total usual residence population transmitted by the national statistical offices to Eurostat in the framework of the Usual Residence Population data collection is used also in other Demographic domains and also household surveys (LFS, EU-SILC). |

18.1. Source data | |||
Apart from the OCMA data, population statistics is also produced by using other administrative registers available to the CSB. The information meeting the needs of the statistical model is that available starting from 2010. CSB has access to the data in administrative registers managed by the following institutions:
The CSB also has information from the Social Security Administration Information System (hereinafter –the SSAIS) on persons who have received social benefits from local governments The information is available from 2012 onwards (in 2012, there are no data on eight municipalities), therefore the SSAIS data are used for specifying population within the age group 18–30 years and for assessing the quality of the model. As of 2017, SSAIS data on people in local government long-term social care institutions and people using night shelter services are available. The CSB is continuously evaluating additional data sources that might be used for the production of official statistics, and, as a result, agreements were concluded on acquisition of additional administrative data that are suitable for the production of population statistics:
[1] Since 2018, RPIVA is a part of University of Latvia and Jāzeps Vītols Latvian Academy of Music. [2] Until 1 January 2016 – Rezekne Higher Education Institution. |
|||
18.2. Frequency of data collection | |||
Register of Natural Persons – each month. Other administrative data – once a year. |
|||
18.3. Data collection | |||
Individual data from administrative data sources are received electronically (via server) (according to the agreements signed between statistical institution and data providers). |
|||
18.4. Data validation | |||
After receiving data from administrative data sources, the number of records, lengh of ID codes (also number of double ID codes) are validated. |
|||
18.5. Data compilation | |||
The statistical classification model has been developed with the help of logistic regression analysis. The aim of the model is to predict the probability of being a resident for each individual. Necessary probability to be included in the usual resident population differs depending on age and gender. Data from Population Register and administrative data sources are used to determine the statuss. With the help of administrative register data, on each person registered within the Register of Natural Persons there are more than 200 characteristics variables developed. |
|||
18.6. Adjustment | |||
According to the Register of Natural Persons there were 2.052 million residents at 01.01.2023; according to the CSB estimation – 1.883 million usual residents – the difference was 175 000 or 9.3%. The reason for difference – non-registered migration (residents do not correct information in the register on their usual place of residence). The highest difference was in age groups 19–24. |
|
|||
The future work of the CSB on methodology of population estimate will continue in two directions – improvement of the existing logistic regression model for population estimate and migration flows, as well as work on development of a new methodology (model) of population statistics. The objective is to develop a methodology based on the data of administrative registers, but not directly using the 2011 Census data which become outdated over the years and less informative about the present situation. |
