Executive Summary

The project was aimed at obtaining new administrative data sources that would help to improve the quality of population statistics in the Slovak Republic while complying with the international methodology. The impulse for these activities is the fact that data sources on the population show long-term discrepancies between statistical data of the Statistical Office of the Slovak Republic (SO SR) and data from administrative data sources (ADSs), in particular at the level of the smallest statistical units (LAU 2). The ongoing consultations with Eurostat on the methodology for the processing of data on foreign-born children and on foreign migration were also an impulse. The activities were carried out with the aim of obtaining relevant ADSs, analysing them, identifying the causes of discrepancies between the official state statistics and ADSs data, and developing a systematic procedure for the use of ADSs. The relevant ADSs for the purposes of the project were as follows: the special select from the Register of Natural Persons and two new ADSs: the ´Special Civil Register´ and the ´Register of Foreigners´. The activities resulted in the creation of the following integrated databases:

on the population stock and demographic structures at municipality level (LAU 2),

on children born abroad to mothers with usual residence in the Slovak Republic,

on foreigners immigrated to the Slovak Republic from abroad.

Introduction Administrative data are most often defined as data that have not been primarily

collected for the statistical purposes. Their main function is to provide reliable

information for the state administration and self-government in various spheres of

public life, in particular, in the areas of planning, budgeting, taxes, education, health

and social insurance. The police and the judiciary draw data from administrative

sources, too.

The population registers have a wide range of uses. According to their focus, they

enable the registration of population in various extents and details, they can be the

basis for population estimates, and they serve also as a sampling frame for population

sample surveys.

The use of administrative data for the statistical purposes is a current trend and it has

several significant advantages. However, it is important to say that administrative data

can never completely replace the direct collection of data through statistical surveys,

but these two approaches can complement each another.

The project is focused on improving the quality of the population statistics, which is

processed and provided by the Statistical Office of the SR, by means of administrative

data sources.

1. Objective and Strategy Objective The aim of the project is to harmonize data on the population number and demographic structures in relevant data sources on population in the Slovak Republic in compliance with the international methodology, and thus to increase the quality of the population statistics in the SR. There are two main groups of data sources on population in the Slovak Republic. On one hand, the official state statistics (statistical surveys) – namely, the population statistics processed by the Statistical Office of the SR – and, on the other hand, administrative data sources. The population data sources have long shown mutually different data, especially at the level of the smallest statistical units (LAU 2). Our intention is to identify the causes of differences between data from the official state statistics and administrative data sources (´ADSs´), and to develop a systematic procedure for the use of ADSs with an emphasis on improving the quality of statistics and (possibly) reducing costs. Strategy The review of available ADSs

Obtaining of relevant ADSs The analysis and statistical adjustment of relevant ADSs

The routine use of ADSs Strategic objectives

The elaboration of a mechanism for the integration of selected ADSs and data from population statistics of the SO SR

The creation of the integrated source database (IZBD)

The feasibility study on the mechanism for harmonization of data from demographic statistics and ADSs at municipality level (LAU 2) in terms of long-term sustainability.

3. Official Names of Eurostat Reporting Obligation

for which Admin Data are Going to be Used

The Statistical Office of the SR collects, processes and provides data of demographic statistics, including data on children born abroad to mothers with permanent residence in the SR, in accordance with the Regulation (EU) No. 1260/2013 of the European Parliament and of the Council of 20 November 2013 on European demographic statistics. The Statistical Office of the SR collects, processes and provides data of migration statistics, including data on migration of foreigners, in accordance with the Regulation (EC) No. 862/2007 of the European Parliament and of the Council of 11 July 2007 on Community statistics on migration and international protection and repealing Council Regulation (EEC) No. 311/76 on the compilation of statistics on foreign workers.

4. Population Data

4.1 Statistical surveys conducted by the Statistical Office of the SR Population censuses and statistical surveys on demographic population changes (vital events and migration) are the basic data sources for the population statistics in the Slovak Republic. These surveys are provided and conducted by the Statistical Office of the SR. Population Census The population census is historically the oldest source of population data. The year 1715 is considered to be a beginning of organized statistical surveys in Slovakia, when countrywide registering of population was conducted in Hungary. Since the mid-19th century, censuses have been conducted by official statistical authorities. At present, the population census is the most extensive statistical survey. It provides data on the number of population living in the Slovak Republic, data on its demographic, cultural, educational, social and economic structure. The population census is an exhaustive statistical survey, which is carried out at ten-year intervals since the establishment of the independent Slovak Republic in 1993, under a separate law for each census and in accordance with European law. Demographic Statistics The registration of demographic population changes in Slovakia goes back to the 18th century. The constitution of the State Statistical Office in 1919 and, especially, the establishment and build-up of the Department of Population Statistics was particularly important for the systematic development of demographic statistics. Currently, demographic statistics is collected by way of statistical survey on demographic population changes conducted each year by the Statistical Office of the SR by means of statistical reports OBYV1-5/12: OBYV1-12 (Statistical Report on the Conclusion of Marriage), OBYV2-12 (Statistical Report on Birth), OBYV3-12 (Medical Report and the Statistical Report on Death), OBYV4-12 (Statistical Report on Divorce), OBYV5-12 (Statistical Report on Change of the Address of Permanent Residence/Report on Migration). The survey covers the whole population of the SR including foreign citizens. It is an exhaustive survey conducted under the Programme of National Statistical Surveys. The Programme of National Statistical Surveys is a legislative document imposing the reporting duty concerning all statistical surveys on reporting units according to § 18, Par. 3 of Act No. 540/2001 Coll. on State Statistics. The reporting units for demographic events include civil registers for births, marriages and deaths, competent courts for divorces, and residence registration offices of municipal and city authorities as well as competent departments of the Ministry of Interior of the SR for the migration of foreigners.

The population census and demographic statistics In the Slovak Republic, demographic statistics is built upon results of population censuses. In the intercensal period (i.e. between two subsequent censuses), the number of population is calculated by means of the balancing method. Figure 1 Demographic balancing equation

4.2 Administrative Data Sources (ADSs) Under the conditions of the SR, there is a significant number of ADSs with data on population. ADSs on the population are significantly differentiated in terms of both the content of population data and population coverage. Similarly, the very organization of information systems of individual managers of ADSs, which ensures data warehouses is very differentiated. Data warehouses of ADSs contain data often obtained from several operating systems, data from external sources, and they do not have the same types of operations defined. For the purposes of the project, there was no special research on the available administrative sources of population data. We used information from the research carried out by the Department of Population Statistics of the SO SR for its own purposes in 2015. The identification of suitable data sources for the purposes of population statistics was based on the aforementioned research on the available administrative sources of population data and on the legislation on the population data recorded by individual ministries. The main criterion was the completeness of coverage of the SR population of interest. In order to improve the quality of population statistics, the following ADSs have proved to be the most appropriate at present:

Register of Natural Persons

Information System ´Register of Foreigners´

Special Civil Register (i. e. the register of birth, marriage and death of citizens of the SR, which occurred outside the SR).

Their suitability arose from the identified problem areas for the purposes of improving the population statistics. The main problem areas in which there is a scope for improving the population statistics include:

Population numbers at the municipality level (LAU 2)

Completeness of the statistical reporting on foreigners

Processing of statistics on children born abroad to mothers with usual residence in the SR.

Register of Natural Persons The Register of Natural Persons (hereinafter referred to as ´RFO´) is the basic register of public administration containing a set of data on natural persons. Data on natural persons recorded in the RFO shall be considered complete and corresponding to reality until proven otherwise. A person who relies in good faith on the data entered in the RFO cannot be disputed by another person that the data are incomplete or do not correspond to reality.

12

The RFO contains data on:

a) citizens with usual residence in the Slovak Republic, b) citizens without usual residence in the Slovak Republic, c) foreigners registered for residence in the Slovak Republic and foreigners granted asylum in the Slovak Republic, d) foreigners without residence in the Slovak Republic, who are registered in information systems operated under a special regulation. The Ministry of Interior of the SR is the manager of the RFO. Special Civil Register In the Slovak Republic, the civil register is the state registration of the personal status of natural persons who were born, married or died in the territory of the Slovak Republic, and of SR citizens who were born, married or died abroad. The civil register consists of a book of births, a book of marriages and a book of deaths. The birth and death books are kept separately for each municipality; the book of marriages is kept jointly for the territorial district of a civil register. Recordable events (i. e. vital events of marriage, birth, death) that have occurred in the SR are registered by the municipality (LAU 2). Recordable events that have occurred outside the SR are registered by the Special Civil Register. The Special Civil Register is a body with a nationwide competence, whose main task is the state registration of birth, marriage and death of citizens of the Slovak Republic, which occurred on: (a) the territory of a foreign country, b) the embassy of the Slovak Republic abroad, c) a ship or an aircraft outside the territory of the Slovak Republic, (d) territory not belonging to any country. Entry into the Special Civil Register shall be made upon a written application accompanied by a birth certificate, a marriage certificate or a death certificate issued by a foreign country, proof of citizenship of the Slovak Republic, record of birth, marriage or death written by a representative office or by a civil register, or other document or other similar proof of vital event. The Special Civil Register is managed by the Ministry of Interior of the SR. The Information System ´Register of Foreigners´ Information systems of the police force keep the following registers in relation to foreigners: a) foreigners’ entry, residence and exit of the country; b) visa applicants, granted or non-granted visa; c) applicants for residence, third country nationals with granted residence and

refused applications for the granting of residence;

13

d) applications for the registration of Union citizens and Union citizens registered for residence;

e) applications for the issuance of documents of residence of the family members of Union citizens and about issued documents of residence of family members of Union citizens;

f) applicants for the issuance of foreigner’s passports and foreigner’s travel documents and about the extension of validity of these documents;

g) third country nationals with invitation letters verified by the police department and about persons inviting third country nationals;

h) lost and stolen travel documents and travel documents and travel documents declared invalid or stolen by issuing state bodies;

i) personas non-grata; j) foreigners, obtained during the provision of border control; k) foreigners with unauthorised residence. The information system ´Register of Foreigners´ is managed by the Bureau of Border and Foreign Police of the Presidium of the Police Force.

5. Road to the Use of New ADSs

The road to the use of relevant ADSs for the purposes of population statistics was divided into 5 basic stages:

1. Obtaining of ADSs 2. Analysis and statistical adjustment of ADSs 3. Creation of the integrated database 4. Routine use of ADSs

5.1 Obtaining of ADSs Register of Natural Persons The Register of Natural Persons has been provided for the SO SR since 2016 annually, in January, on the reference date of 31 December of the previous year. It is used by several statistical areas, and it is suitable also for the purposes of population statistics. Based on the agreement between the MI SR and the SO SR, data are provided on external storage media. Data are imported into ORACLE schemes of the SO SR´s information system. Special Civil Register In order to obtain data from the ADS ´Special Civil Register´, the SO SR initiated and conducted negotiations between the representatives of the SO SR and the MI SR. The main goal of the session was to agree on providing data on foreign-born children in electronic format from the information system of the Special Civil Register in the following two steps:

As a first step, the Special Civil Register will provide an initialization data set for the reference years 2012 – 2018,

The second step will be the creation of an online system for the permanent automated transfer of data on foreign-born children from the information system of the Special Civil Register to the information system of the SO SR.

Following the conclusions of the 1st session, the SO SR sent an official written request to the MI SR, asking for the provision of electronic data on foreign-born children for the reference years 2012 – 2018 in the form of an initialization data set. The first initialization data set from the Special Civil Register was delivered to the SO SR in April 2019. After importing and analysing of the data set, shortcomings were found there. Namely, some of the required variables were missing, and the completeness of available variables was insufficient or was not according to the defined structure. Therefore, the SO SR again requested the Special Civil Register to provide a new data export in a higher quality. The Special Civil Register delivered the data set again in May 2019. After analysing that data set, there were still erroneous entries there. They were corrected as part of the third data set that was delivered to the SO SR in June 2019. The MI SR provides data on external storage media on the basis of a take-over certificate (receipt form). Data are imported into ORACLE schemes of the SO SR´s information system.

15

IS Register of Foreigners In order to obtain data from the ADS ´ECU´, two working sessions of the representatives of the SO SR and the UHCP PPZ took place, in October and December 2018, with the aim to agree and to establish the electronic transfer of data on residence of foreigners from the UHCP PPZ´s information system named ´Register of Foreigners (ECU)´. For the purposes of population statistics, the SO SR asked for two types of data batches from the ECU, as follows:

Stock of foreigners on 31 December

Monthly data on migration of foreigners (to / from the SR and within the SR). Negotiations were complicated. Initially, the UHCP PPZ proposed that the SO SR draw data on foreigners directly from the ADS ´Register of Natural Persons´. However, the RFO contains limited data on foreigners registered for residence in the SR and on foreigners granted asylum in the SR (i. e. only to the scope of data in the document on residence). So the RFO does not contain all the necessary data for the statistical processing of migration flows. In particular, the following data are missing: country of birth, country of previous residence, level of (completed) education, marital status, nationality and country of emigration. The SO SR submitted to the ECU manager the complete list of necessary variables for monthly and annual electronic data collections on foreigners. The first task of the ECU manager was to provide a test export of data on immigrated / emigrated foreigners for the year 2018 for the purpose of comparison with the data that were delivered to the SO SR within its statistical survey on migration by means of statistical reports ´OBYV5-12´ in 2018. Until 31 July 2019, the abovementioned data requirement was met only partially: the ECU provided only data on immigrants in 2018 on a monthly basis. The data were provided on the basis of the SO SR´s official request to the MI SR. The data were imported into ORACLE schemes of the SO SR´s information system. The main reason for not providing of data in the required scope is the need to do sophisticated selections of micro-data from the ECU information system, which requires special expertise, extra processing time and extra financial resources.

5.2 Analysis and Statistical Adjustment of ADSs

5.2.1 ADS – Register of Natural Persons

The RFO contains about 100 variables. For the purpose of harmonisation of the

population number at municipality level (LAU 2), only the following RFO data were

analysed: identification variable (personal identification number), basic variables for

demographic structures, i. e., sex (sex code, sex name) and age (date of birth), and

the residence variable (municipality code, municipality name).

Personal identification number Completeness of PIN records Total records 6 848 316

of which

Completed records 6 256 126

Uncompleted records 592 190

The completeness of the personal identification number (PIN) is one of the key factors affecting the capability to link the RFO as a reference administrative source of data on natural persons with other data sources. The most numerous group of natural persons without completed PIN are foreigners without residence in the SR who came into contact with the public administration. However, for the purposes of demographic statistics, this group of persons is irrelevant. Logical checks:

modulo 11 – each correct PIN must be divisible by 11 without the remainder

admissible values in the 3rd position – the 3rd figure in the PIN indicates the sex of the natural person. The numbers 0 and 1 indicate the male, the numbers 5 and 6 indicate the female.

the existence of duplicates in the PIN – mainly because there are records on various types of residence of a natural person, as well as multiple records of foreigners who came into contact with the public administration.

Completeness of PIN records for the purpose of harmonisation of the population number

Total records 5 610 425

Uncompleted records 0

Sex Completeness of sex records

Logical checks: There is not such a case where if the verbal name of sex is filled in, the numerical code of sex is not filled in. Sex can be added also from the PIN: if the 3rd place in the PIN (SUSR_ID) is ‘5‘ or ‘6‘, the sex is female. However, in the data source, there is not such a case where the sex is missing and the PIN is filled in. The correctness of the sex record was verified via PIN, i. e., if the figures 5 and 6 appear in the PIN in the 3rd place, the sex must be female, otherwise male. There is no error of this type throughout the database. Completeness of sex records for the purposes of harmonisation of the population number


of which



Age (Date of birth) The separate variable ´age´ is not in the RFO. Thus, the SO SR calculates it from the date of birth and from the PIN. Completeness of age records


of which



Logical checks:

´Date of birth´ format – in all records it was ´YYYY-MM-DD´

There can be only digits 1-31 in ´DD´ and only 1-12 in ´MM´´– the values were correct in all records

The date of birth was derived from the PIN in 6 255 856 records (only those PIN that had the format XXXXXX/XXX or XXXXXX/XXXX) – a check between the date of birth and the date of birth derived from the person´s PIN showed a total of 919 records that did not correlate. In some cases there is an inconsistency between the PIN and the date of birth, in other cases the PIN is bad, e. g., although it contains 10 or 11 characters including a slash, there are dots (14.12./1980) in its record, or the birth number consists of ´fictional´ 10 characters – the latter is especially in the case of foreigners).

Logical adjustments: In terms of completeness, the database contained 20 records with PIN but without date of birth. After the analysis, the date of birth can be added in all 20 records. Completeness of age records (date of birth) for the purposes of harmonisation of the population number

Completeness of records on the municipality of usual residence Total records 6 848 316

Of which



Logical checks:

There is not such a case where if the verbal name of the municipality of residence is filled in, the numerical code of the municipality is not filled in.

Numerical and verbal items were verified; verbal names of municipalities correctly correspond to the numerical codes of municipalities

The data set from the Special Civil Register contains records on births abroad in the period 1916 – 2018.

21

The statistical processing of data on foreign-born children by year of birth can be divided into 2 main groups:

records for the years 1916 – 2011 The statistical processing was carried out in such a way that all the children who were born abroad to mothers with the usual residence in the SR, and who were registered with a Special Civil Register, were included in the birth statistics.

records for the years 2012 – 2018 The statistical processing was carried out in such a way that children born abroad to mothers with the usual residence in the SR were included in the immigration statistics, but only if the child was registered with a Special Civil Register and also registered for the permanent (usual) residence in the SR. This change in methodology was implemented in accordance with the Act No. 253/1998 Coll. on Reporting of Residence of Citizens of the Slovak Republic and on the Register of Citizens of the Slovak Republic, as amended. The completeness of variables required from the Special Civil Register in electronic format varies. The highest level of completeness is found for the variables ćountry of birth of the child´, ´date of birth of the child´, ćhild's sex´, ´vitality´, ćountry – mother's / father's usual residence´ (100% completeness). The PIN of the child is not filled in only 4 records, the child's citizenship is not filled in only 476 records. There is also a relatively high level of completeness for the variables on parents: country of birth and citizenship (completeness in the range of 97 – 99%). The father's PIN is filled in about 70% and the mother's PIN in 90%. The lowest level of completeness is for the variables ´highest educational level achieved by mother / father´ (5 – 9%). Father's nationality is filled in 37% and the mother's nationality in 51%.

Chosen analyses are in Annex 1. The issue of foreign-born children is a problem currently being addressed at the EU level. The methodological approach applied by the Slovak Republic since 2012 is not considered correct. Therefore, one of the aims of this project is to prepare data in such a way that the approach recommended by Eurostat could be applied in the SR. This means that the following data sets will be created:

Children born in the SR to mothers with the permanent (usual) residence in the SR

Children born in the SR to mothers with the permanent (usual) residence outside the SR

Children born abroad to mothers with the permanent (usual) residence in the SR

Children born abroad to mothers with the permanent (usual) residence in the SR and, at the same time, registered for the permanent (usual) residence in the SR.

22

These data sets will allow:

all children born abroad to mothers with permanent (usual) residence in the SR are included in the SR birth statistics

or

children who were born abroad to mothers with permanent (usual) residence in the SR and, at the same time, registered for permanent (usual) residence in the SR, are included in the SR birth statistics

or

children born abroad to mothers with permanent (usual) residence in the SR and, at the same time, registered for permanent (usual) residence in the SR, are included in the immigration statistics

and also

to provide Member States with data on children born in the SR to mothers with usual residence in their country.

5.2.2.1 The Estimation of Birth Weight, Birth Length and Pregnancy Week The most serious problem in the development of this data processing system is the absence of medical data on the childbirth that took place outside the SR, namely the ´birth weight´, the ´birth length´ and the ´pregnancy week´. Therefore, the SO SR has developed and applied the methodology for adding these data to every record of foreign-born child. In order to estimate the birth weight, birth length and pregnancy week in the database on children born abroad to mothers with permanent residence in the SR, data from the SO SR´s source database ZBD OBYV 2-12 for the years 2012 – 2018 have been analysed. The estimation of the birth weight The variable ´mother´s age at childbirth´ is not in the data file from the Special Civil

Register (Table 2). Nevertheless, the Special Civil Register provides the personal

identification number (PIN). The PIN can be used to derive the ´date of birth of the

mother´. Subsequently, the DATE function can be used to calculate the mother´s age

at childbirth. The calculated variable ´mother´s age at childbirth´ is in the integrated

source database Natality (IZBD Natality, Annex 5, Table 5.1).

Appropriate (5-year) age intervals of mothers and appropriate birth weight

intervals were determined (according to the standard code-list used for the

processing).

From OBYV 2-12 data, the percentage of new-born children at determined birth weight intervals were calculated for each age group of mothers.

Tables were created for each year of birth of child (2012, 2013, ...) with the numbers of mothers by age groups (15 – 19, 20 – 24 etc.), who gave birth abroad.

The percentage of children born to mothers in the respective age group at individual birth weight intervals (from Obyv 2 - 12) was applied to the data from step 3 so that the ratio could be maintained at individual age and birth weight intervals. This step gave expert estimates of the numbers of foreign-born children at their individual birth weight intervals.

Estimated values to add the weight (in grams) of a child born were imputed to each age of mother using the RANDBETWEEN function, which returns a random number from the selected interval. Then these weights were rounded to tens of grams.

The child's birth weight was imputed solely on the basis of a correlation with the mother´s age, provided that the usual residence of the mother is in the Slovak Republic. Other variables that could correlate with the birth weight have:

either a low level of completeness (the highest level of completed education of the mother – 13.24%),

or, as for the country of birth of the mother, only 3.23% of mothers were born in the

country other than the SR, and, as for the citizenship of the mother, only 1.49% of mothers had the citizenship

other than the SR.

24

Only the biological characteristic (mother´s age) was taken into account, and not socio-economic factors. The underlying tables for imputations for each of the years 2012 – 2018 are in Annex 2. The estimation of birth length and pregnancy week For the imputation of the birth length (in cm) and pregnancy week, the LOOKUP function was used to assign the corresponding birth length and pregnancy week to the respective birth weight according to data from Obyv 2-12.

Thus, each birth record was matched with the birth weight, birth length and the pregnancy week. The individual imputation steps were used for each reference year.

5.2.3 ADS – Register of Foreigners

The Statistical Office of the SR asked the manager of the ADS ´Register of Foreigners´ to provide data in the structure meeting the requirements of migration statistics.

Metadata for the data in question were analysed as well. The following variables were discussed:

´Date of registration´ – the item actually represents the date of submission of the application for a residence permit

´Reason for migration´ – the ADS manager does not record this piece of data; there are negotiations on the possibility of introducing this item into the UHCP´s information system

28

Éducation´ – it will be provided according to the UHCP´s code-list, which the SO SR will transform into its code-list

Ćitizenship´ – a 3-letter acronym from the SO SR´s code-list will be used, and a maximum of 4 citizenship records will be registered

Ńationality´ – the UHCP´s code-list will be used, which the SO SR will transform into its code-list

An item to indicate any additional changes in the file (whether it is a change in the date of registration, date of birth, etc.) will be added into the required structure of the monthly collection of data on foreigners from the ECU information system.

As a standard, the SO SR receives data on the number of foreigners from the IS ECU as of 31 December of the reference year. The new structure and form of provision of these data were discussed.

5.3 Creation of Integrated Databases

The mechanism for the integration of ADSs into databases of the SO SR

The proposal for the mechanism of the integration of ADSs consists in:

identification of variables suitable for integration,

creation of variables for integration,

transformation of variables into uniform formats,

determination of the method of data linkage through variables. The integration of ADSs for the project purposes includes three separate integrations of databases:

Linking of SO SR data from the source database ´Bilancie2018´ with data from the RFO.

Linking of SO SR data from the source database ´Migration (OBYV 5/12)´, namely, the select of data on foreign-born children registered for usual (permanent) residence in the SR, with data from the Special Civil Register.

Linking of SO SR data from the source database ´Migration (OBYV 5/12)´, namely, the select of data on immigrated/emigrated foreigners from/to abroad, with data from the IS ECU.

5.3.1 Integrated Source Database ´Balance´ (IZBD Balance)

The integration of the source database ´Bilancie2018´ and the RFO database (data as of 31 December 2018) was proposed in order to harmonize demographic statistics and data from ADSs at municipality (LAU 2) level in terms of long-term sustainability. The numbers of population in different data sources (SO SR, RFO, municipal records) vary, and there is a strong need to harmonize these data as much as possible. With the supply of new ADSs and integration of the existing databases, it would be possible to correct or, in some cases, even completely eliminate the discrepancies in the numbers of population at municipality level. The preparation of the data set of the source database ´Bilancie2018´

The source database ´Bilancie2018´ contains 5 450 421 records on inhabitants with usual (permanent) residence in the SR; 1 record in the database represents just 1 inhabitant.

The source database ´Bilancie2018´ does not contain duplicate records, and its completeness is 100%.

There is no need for logical checks and logical adjustments because they are running in the process of creation of this database.

The source database ´Bilancie2018´ consists of 13 basic variables.

The variables are filled in with standard code-list values used by the SO SR; there is no need to transform the code-list values in the variables. Only the date of birth was modified – to the format ´DDMMYYYY´.

For the needs of data linking, the variables ´date of birth´, ´age´, ´sex´, ´municipality of usual residence´ were selected.

31

The preparation of the RFO data set

The entire RFO database contains 6 848 316 records.

For the purposes of harmonization, only unique records on persons with usual (permanent) residence were selected.

Within the process of data preparation, the database was cleared of duplicate records.

The variables 'date of birth', 'sex' and 'municipality of usual residence' were selected for the data linking. The variable ´personal identification number´ was selected as an auxiliary variable.

´Date of birth´ was modified to the format ´DDMMYYYY´.

´Age of person´ was derived from the date of birth.

´Code of the municipality of usual (permanent) residence´ was transformed by the code-list of the SO SR No. 0051.

The database ready for the linking contained 5 610 425 records. The linking of databases Two basic databases were integrated. They should cover the total population of the SR. The source database of the SO SR ´Bilancie2018´ contained 5 450 421 records and the RFO database contained 5 610 425 records. Due to the absence of a unique identifier in both databases (the personal identification number as a unique identifier of a person is only in the RFO database), identifiers were created to link the databases. The identifiers were created for each record in both databases: Table 7 Types of identifiers for the integration of databases

Identifier Variables used Example of identifier

ID1 Date of birth, sex, municipality of usual residence, serial number of identifier

0101195015299471

If the created identifier was unique, it was complemented by the number ´1´ following after the series of variables. If there were several identical identifiers in databases, each identifier was assigned a serial number according to the order in the database;

32

ascending order by identifier ID1 in the first linking, or ascending order by identifier ID2 in the second linking. This ensured the uniqueness of created identifiers for individual records. The integration of databases was done in two steps:

Step 1 – Linking of databases via the identifier ID1. The identifier contained the variables: ´date of birth´, ´sex´, ´municipality of usual residence´, and ´serial number of record's occurrence´. All records in databases were linked.

Step 2 – Linking of databases via the identifier ID2. The identifier contained the variables: ´age´, ´sex´, ´municipality of usual residence´, and ´serial number of the record's occurrence´. We linked only those records in databases that were not matched in Step 1.

Identifier for integration Number of records

ID1 4 884 906

ID2 458 865

N1 106 650

N2 266 654

The identifier of record matches (ID) has 4 categories:

ID1 means that the record was matched in Step 1 – via the identifier ID1.

ID2 means that the record was matched in Step 2 – via the identifier ID2.

N1 means the unmatched record that is only found in the Bilancie2018.

N2 means the unmatched record that is only found in the RFO. The resulting database contains 3 types of data for each municipality:

data on inhabitants who are in both the RFO and Bilancie2018,

data that are only in Bilancie2018,

data that are only in the RFO. The database contains 11 items for each municipality:

Column A OBEC_TP_BIL municipality of usual residence of person by the SO SR

Column B POHLAVIE_BIL sex of person by SO SR data Column C DAT_NAR_BIL date of birth of person by SO SR data Column D VEK_BIL age of person by SO SR data Column E RC_RFO PIN of person by RFO data Column F OBEC_TP_RFO municipality of usual residence of person by the RFO Column G POHLAVIE_RFO sex of person by RFO data Column H DAT_NAR_RFO date of birth of person by RFO data Column I VEK_RFO age of person by RFO data Column J ID identifier of record matches Column K KOD_OBCE item for export containing the code of municipality

In connection with the data linking process, it should be emphasized that the data linking process is probabilistic due to the lack of a unique identifier in both databases. In other words: in Step 1, records of inhabitants with the same date of birth, sex and

33

municipality of usual residence were matched. In Step 2, records of inhabitants with the same age, sex and municipality of usual residence were matched. That means, if 2 persons with the same date of birth and sex reside in one municipality, it is not possible to match each one unambiguously within the data sources used. The integrated database was used also to create sub-files with data on municipalities´ inhabitants; for each individual municipality a separate sub-file containing data just on its inhabitants was created. The use of the integrated database On the basis of the offer made by the SO SR, municipalities can request the data file exported from the integrated database. The file details the differences between two basic population databases in the SR. Based on municipal records that can be understood as a secondary administrative source, and based on the SO SR´s analysis of the causes of possible differences (Table 9), this comparative activity can help municipalities to eliminate a significant part of the differences. Besides the causes, the SO SR lists also possible ways to eliminate data discrepancies. At the same time, the SO SR recommends to implement this process by 2021, which is the year of population censuses in the EU. Table 9 Possible causes of differences in the numbers of inhabitants at LAU2 level

5.3.2 Integrated Source Database Ńatality´ (IZBD Natality)

The integration of databases, part ZBD OBYV5-12 (Children born abroad and registered for residence in the SR) and the database from the Special Civil Register (Children born abroad), was proposed to create a 'flexible' database on children born abroad to mothers with usual (permanent) residence in the SR. Flexibility lies in the ability to divide the set of births into the disjoint subsets:

children born abroad and registered for residence in the SR

children born abroad and not registered for residence Records from databases for the reference period 2012 – 2018 were used for the integration; it is the period from the last population census and also the period of the methodology change implemented by the SO SR. The preparation of the data file ´ZBD OBYV 5-12´

Data on children born abroad who registered for usual (permanent) residence were selected from OBYV5-12 databases. These children have the value ´9´ in the serial number of record, which distinguishes them from children born abroad to mothers who are not resident in the SR.

The total number of records to be linked was 14 409

Variables ´personal identification number´, ´date of birth´, ´sex´ and ćountry of birth´ were used for the linking. ´Date of birth´ was prepared in the format ´DDMMYYYY´. The preparation of the data file ´Special Civil Register´

There was no special need to select records in the database of the Special Civil Register. The whole set of records was linked.

The total number of records to be linked was 58 972.

Variables ´personal identification number´, ´date of birth´, ´sex´ and ćountry of birth´ were used for the linking.

´Date of birth´ was modified into the same format as in the OBYV 5-12 database (DDMMYYYY). Ćountry of birth´ was assigned the numerical code by the code-list. The linking of databases The linking of the databases was done in three steps. In the first step, the records were linked via the personal identification number. In the second and third step, unmatched records were linked via the created identifiers ÍD1´ and ÍD2´. The method of the construction of identifiers is in Table 10.

In the construction of identifiers, the variables ´date of birth´, or ´year of birth´, ´sex´ and ´country of birth´ were joined and, subsequently, sorted in ascending order. After sorting, the identifiers were assigned a serial number by the number of occurrences in the database, i. e., if the identifier occurred only once in the database, it was assigned the number 1; each successive occurrence of the same identifier was assigned a serial number by the number of occurrences. This ensured the uniqueness of the identifiers created. Table 11 Matches of records of ZBD OBYV5-12 (children born abroad and registered for residence in the SR) and Special Civil Register database

Unmatched - ZBD OBYV5-12 92

Unmatched - Special Civil Register 44 655

The number of records in the database of the Special Civil Register is significantly higher than the number of records from the ZBD OBYV5-12 file. The main reason is that ZBD OBYV 5-12 includes only those foreign-born children who were also registered for usual (permanent) residence in the SR. With respect to the SO SR database, a total of 14 317 records from the Special Civil Register were matched with the ZBD OBYV5-12. 92 unmatched records remained in the ZBD OBY5-12 database, and 44 655 unmatched records in the database of the Special Civil Register. Most of the matched records were matched via the personal identification number (49.8%). The use of the integrated database The integrated database allows for a flexible breakdown and, at the same time, it meets other requirements such as the maximum coverage and necessary demographic structures. The maximum coverage is ensured by data source itself, which is the Special Civil Register. The Special Civil Register records all applications for

38

registration immediately into the IS. After the integration, demographic structures were processed to fit both birth statistics and migration statistics. This is particularly the case of imputations of medical data (Chapter 5.2.2). These procedures have made it possible to statistically process this part of population according to any methodological guideline, whether in migration statistics or birth statistics, using the whole file or the selected part.

5.3.3 Integrated Source Database ´Migration´ (IZBD Migration)

The integration of databases, part ZBD OBYV5-12 (immigrants/emigrants from/to abroad) and the IS ECU was proposed to improve the quality of statistics on foreign migration, especially with regard to completeness. Given the problems caused especially by technical difficulty to export data from the IS ECU, it was possible to integrate only data on immigrants to the SR. Data in both databases, SO SR and UCPCP PPZ, contain only records for the reference year 2018. The preparation of the data file ´ZBD OBYV 5-12´

The data file ´ZBD OBYV 5-12´ for the reference year 2018 contains a total of 108 965 records.

The data file ´ZBD OBYV 5-12´ contains both internal and foreign migration, immigrants and emigrants for/from usual (permanent) residence in the SR irrespectively of citizenship.

For the purposes of the project and comparison of data with IS ECU data, it was first necessary to select from ZBD OBYV5-12 only immigrants who had ćountry of previous residence´ other than the SR and ćountry of new residence´ was the SR. This file contained 7 253 records (all immigrated foreigners and citizens of the SR). In the second step, the selection was limited to immigrants who had ćitizenship´ other than the SR – thus, 2 869 records were selected (only foreigners).

The preparation of the data file from the IS ECU – immigrants

The ECU file contains records on immigrants (12 687) who have the citizenship other than the SR; the citizenship is not filled in in 171 records only.

Immigrants for usual (permanent) residence in the SR were selected from the file; i. e., foreigners who had moved within the SR were excluded. After processing, the file contained 6 814 records.

´Date of birth´ format was unified to ´DDMMYYYY´.

Codes of citizenship were transformed by the code-list of the SO SR No. 0088. The linking of databases The actual comparison of records in both databases shows that the ECU database contains a larger number of records on immigrants from abroad than the SO SR receives from OBYV5-12 reports. Databases were linked in 3 steps. In the first step, they were linked via personal identification number, which is a unique identifier for natural persons in the SR. In the second and third steps, they were linked via created identifiers. Table 12 Types of identifiers for the integration of databases

The linking of databases via personal identification number has proved to be ineffective at present due to the completeness in ZBD OBYV 5-12: there were only 87 complete personal identification numbers in ZBD OBYV 5-12 in the year 2018. Therefore, in order to link databases, identifiers were created from the variables that identify the person as close as possible, and have a relatively high completeness.

In the second step, in both databases, an identifier was created from the variables ´date of birth´, ´sex´ and ´citizenship´. After sorting, identifiers were assigned a serial number by number of occurrences in the database. If the identifier was only once in the database, it was assigned the number 1. Each subsequent occurrence of the same identifier was assigned a serial number by number of occurrences. This ensured uniqueness of created identifiers.

In the third step, records were linked via the identifier ´ID2´ (age, sex and citizenship).

After three linkages, a total of 2 762 records were matched, which is 96.3% with respect to the ZBD OBYV5-12 database. 107 unmatched records remained in the OBYV 5-12 database and 4 052 unmatched records remained in the ECU file.

Unmatched ZBD OBYV5-12 107

Unmatched ECU 4 052

Unmatched data in ZBD OBYV5-12 are the result of minor errors that occur in filling in OBYV5-12 reports or in typing data from paper form of OBYV5-12 into electronic form.

The rate of unmatched ECU data is statistically very high. Part can be explained by time shifts in the fulfilment of reporting duty, but it seems real that it is either the result of failure to report to the SO SR or an erroneous export from the IS ECU. Therefore, it is necessary to continue analyses of data for the next reference periods in future. The comparison of matched records For the analysis of matched records, the municipality of usual (permanent) residence of the migrant and the date when the migrant was registered on residence were compared.

41

In all matched records, the municipality of usual residence was filled in within both databases. Table 14 Compliance of the municipality of usual residence between ZBD OBYV5-12 (immigrants from abroad) and ECU records

Municipality of usual residence Number Filled-in municipality - ZBD OBYV5-12 2 762

Filled-in municipality - ECU 2 762

Identical municipality of usual residence 2 142

Different municipality of usual residence 620

In records where the municipality of usual residence does not comply between ZBD OBYV5-12 and ECU databases, this is usually the case where only a district (LAU1) is listed in the ZBD OBYV5-12 database and a municipality itself (LAU2) - where the person registered for usual residence - is listed in the ECU database. The municipality listed in the ECU falls in the district listed in the ZBD OBYV5-12 database. Date of registration for residence was compared in matched records. Date of registration was filled in in all matched records (2 762 records). 2 133 records (77,2%) had the same date of registration for residence in both databases. Discrepancies in municipality of immigration and in date of registration may affect the demographic balancing (calculation of population changes) at municipality level and the monthly demographic balancing. The analysis showed that ECU has more precise data than those obtained through OBYV 5-12 reports.

5.4 Routine Use of ADSs

The selected ADSs have potential to be routinely used for the purposes of population statistics. The Register of Natural Persons is provided routinely to the SO SR; after the delivery of a data batch, this is imported into SO SR´s Oracle schemes in a standard manner. Its acquisition was not the subject of the project, but the subject was to examine its use for the needs of population statistics and its improvement at municipality level. The process has been started but it is long-term, and the first relevant results will be measurable around 2021 (the year of the population census). The Special Civil Register supplied the initialization file for the years 2012 – 2018, an annual data batch is agreed for the future. For now, this is the provision of data through indirect integration, i. e., via external data media or FTP. The data allow the processing of birth statistics in different variations. The Register of Foreigners supplied only a part of the necessary data, which was analysed. Their potential for improving the quality of population statistics is high especially in terms of completeness but also in terms of administrative burden. In case of a routine data provision, whether by direct or indirect integration, it would be possible to eliminate paper-based reporting on migration of foreigners (by means of OBYV5-12 reports in paper format), and thus to eliminate the performance of reporting units (filling in and sending paper reports) as well as of the SO SR (digitization of paper reports). Negotiations and other activities will continue, the next negotiation between the SO SR and UHCP PPZ is expected in September 2019.

Conclusions – Sustainability of the Project´s Achievements In terms of long-term sustainability, the use of administrative data sources ´Register of Natural Persons´ and ´Special Civil Register´ have been set up for the routine processing. The integration of the RFO and ´Bilancie2018´ launched the process of harmonisation of the number and demographic structures of population at municipality level (LAU2). Its completion is expected by the 2021 Population Census. The integration of data from the Special Civil Register and SO SR data on the demographic population change created conditions for the flexible processing of data on births in various variants. When definitive methodological guidance is provided by Eurostat, the SO SR is able to prepare data on births in required structures with retroactive effect (i. e. since 2011). The challenge for these ADSs is the transition from the indirect integration to a direct integration. In the case of the administrative data source ´Register of Foreigners´, the process continues. The ambition is a direct integration of data on immigrated and emigrated foreigners into the IS of the SO SR. Within the project, we have managed to test data on immigrants. Their suitability has been confirmed. The process will continue by obtaining and testing data on emigrants to abroad. The biggest obstacles to immediate integration are the organisations of data warehouses, from which data are selected. In order to meet the arising requirements, there is often a need for technological adjustments, which have to be solved systemically, and thus they are time consuming. In the case of a successful integration of ECU data on immigrants and emigrants, not only will the data quality increase (particularly in terms of completeness), but also the costs of data digitization in the SO SR´s environment will decrease.

45

Basic Data Configuration In terms of the KOMUSO data configuration typology, this is the Configuration 2: Overlapping data sources. Data characteristics:

Data sources consist only of micro-data (data of the SO SR and data from administrative sources),

Data cover the entire target population,

Data are surveyed as of 31 December

Some variables overlap between different data sources.
