EU-SILC Description Target Variables Personal Register (R-file) RB010: Year of the survey BASIC DATA (Basic personal data) Cross-sectional and longitudinal Reference period: current Unit: all current household members (of any age) and former household members Mode of collection: interviewer Values year (4 digits) 2011 Operation - 1 - EU-SILC Description Target Variables Personal Register (R-file) RB020: Country BASIC DATA (Basic personal data) Cross-sectional and longitudinal Reference period: constant Unit: all current household members (of any age) and former household members Mode of collection: frame Values BE Belgique/Belgïe BG Bulgaria CZ Czech republic DK Denmark DE Deutschland EE Estonia IE Ireland GR Elláda ES España FR France IT Italia CY Cyprus LV Latvia LT Lithuania LU Luxembourg HU Hungary MT Malta NL Nederland AT Österreich PL Poland PT Portugal RO Romania SI Slovenia SK Slovak republic FI Suomi SE Sverige UK United Kingdom CH Switzerland HR Croatia IS Iceland NO Norway TR Turkey 2011 Operation - 2 - EU-SILC Description Target Variables Personal Register (R-file) RB030: Personal ID BASIC DATA (Basic personal data) Cross-sectional and longitudinal Reference period: constant Unit: all current household members (of any age) and former household members Mode of collection: frame, register or interviewer Values (cross-sectional) ID number see construction in chapter 'General description' RB031: Year of immigration BASIC DATA (Basic personal data) Cross-sectional and longitudinal Reference period: constant Unit: all current household members (of any age) and former household members Mode of collection: frame, register or interviewer Values 1890-year of the survey Note: If the person immigrated before 1890 the variable will be filled in with the value 1890. The purpose of this variable is twofold1: 1) to identify the people who entered the country in the last years (maximum duration = length of the rotational panel) to know if these people were in the sample frame at the time of the sample selection (for longitudinal weighting purposes); 2) to study the population of migrants in a broad sense, i.e. to evaluate the size and major characteristics of the people who entered the country when recording the last entry in the country. The considered period of immigration should be since the person was born. In case of major problems to obtain the information, the considered period can be limited to the panel duration of EU-SILC survey (i.e. last 4 years). In the case of boundary changed and the person lives at the same address, this is not considered as immigration and the flag -2 should be used. Reintegration in the country of origin or in the country of birth is considered as immigration for this variable. Only immigration between countries should be considered, immigration among regions within country should not be taken into account. 1 To collect this variable starting from the 2010 operation onwards was agreed during the 2009 Living Conditions Working Group meeting. Nevertheless, it was kindly asked to countries to already fill in this variable from the 2008 operation onwards as much as possible, knowing that in the majority of cases this information should be available from population registers. 2011 Operation - 3 - EU-SILC Description Target Variables Personal Register (R-file) RB040: Current household ID BASIC DATA (Basic personal data) Longitudinal Reference period: current Unit: all current household members (of any age) and former household members Mode of collection: frame, register or interviewer Values ID number see DB030 RB041: Personal ID BASIC DATA (Basic personal data) Cross-sectional Reference period: last wave Unit: all current household members (of any age) Mode of collection: frame, register or interviewer Values ID number see identification numbers This variable is to be filled by the countries implementing a rotational panel or a pure panel. It is only defined for the persons who have been eligible for follow-up as panel persons. Otherwise, the variable is coded missing and flagged with -2 (not applicable). RB041 provides for those persons the same identification code as for the year of their last interview so that we can merge the data of these two consecutive years. For each eligible person, RB041 results from concatenating the personal identification code (SILC variable RB030) for the year of the last interview with a digit accounting for the corresponding panel wave of the interview. The coding of RB041 is illustrated in the next figure. 2003 2004 2005 Year 2011 Operation - 4 - EU-SILC Description Target Variables Personal Register (R-file) Let Si, i∈{1,2,3,4}, denote the four sub-sample of « panel » persons in 2005, i.e. persons eligible for follow-up (in 2006). Let RB030(yy) denote the personal identification codes at year yy. Then, we have: - RB041(S1) = RB030(2004)!!2 - RB041(S2) = RB030(2004)!!2 - RB041(S3) = RB030(2004)!!1 - RB041(S4) = missing (RB041_F=-2) (!! means "concatenation") In fact RB041 = (RB030) of the previous year concatenated with the number of years the person is in the survey. So, in the 2010 datafile: 1) if the person was selected to be interviewed for the first time in the SILC operation 2009, RB041 for this person will be equal to (RB030) from the 2009 datafile concatenated with '1'; 2) if the person was selected to be interviewed for the first time in the SILC operation 2008, RB041 for this person will be equal to (RB030) from the 2009 datafile concatenated with '2'; 3) if the person was selected to be interviewed for the first time in the SILC operation 2007, RB041 for this person will be equal to (RB030) from the 2009 datafile concatenated with '3'. RB050: Personal cross-sectional weight BASIC DATA (Basic personal data) Cross-sectional Reference period: constant Unit: all current household members (of any age) and all former household members Mode of collection: constructed Values 0+ (format 2.5) weight (see bellow the required format) See construction of weights in chapter ‘Introduction’ Required format In principle, according to the regulation, these weights had to be coded with 2 integers and 5 decimals. But, that cause problems if the weights have at least 3 integers. That’s why, in practice, personal cross-sectional weights will be coded with at least one integer and 5 decimals. 2011 Operation - 5 - EU-SILC Description Target Variables Personal Register (R-file) RB060: Personal base weight BASIC DATA (Basic personal data) Longitudinal Reference period: constant Unit: all current household members (of any age) and former household members Mode of collection: constructed Values 0 (format 2.5) weight (see bellow the required format) See construction of weights in chapter ‘Introduction’ The personal base weight can have the value 0, namely for non panel persons. Required format In principle, according to the regulation, these weights had to be coded with 2 integers and 5 decimals. But, that cause problems if the weights have at least 3 integers. That’s why, in practice, personal base weights will be coded with at least one integer and 5 decimals. RB062: Longitudinal weight (two-year duration) BASIC DATA (Basic personal data) Longitudinal Reference period: constant Unit: all current household members (of any age) and former household members Mode of collection: constructed Values 0 (format 2.5) weight See construction of weights in chapter ‘Introduction’ RB063: Longitudinal weight (three-year duration) BASIC DATA (Basic personal data) Longitudinal Reference period: constant Unit: all current household members (of any age) and former household members Mode of collection: constructed Values 0 (format 2.5) weight See construction of weights in chapter ‘Introduction’ 2011 Operation - 6 - EU-SILC Description Target Variables Personal Register (R-file) RB064: Longitudinal weight (four-year duration) BASIC DATA (Basic personal data) Longitudinal Reference period: constant Unit: all current household members (of any age) and former household members Mode of collection: constructed Values 0 (format 2.5) weight See construction of weights in chapter ‘Introduction’ 2 RB070: Month of birth BASIC DATA (Demographic data) Cross-sectional and longitudinal Reference period: constant Unit: all current household members (of any age) and former household members Mode of collection: household respondent or register Values 1 - 12 month RB080: Year of birth BASIC DATA (Demographic data) Cross-sectional and longitudinal Reference period: constant Unit: all current household members (of any age) and former household members Mode of collection: household respondent or register Values 1890-year of the survey Note: If the person is born before 1890 the variable will be filled in with the value 1890 2 To construct this variable starting from the 2010 operation onwards was agreed during the 2009 Living Conditions Working Group meeting. 2011 Operation - 7 - EU-SILC Description Target Variables Personal Register (R-file) RB090: Sex BASIC DATA (Demographic data) Cross-sectional and longitudinal Reference period: constant Unit: all current household members (of any age) and former household members Mode of collection: household respondent or register Values 1 Male 2 Female RB100: Sample person or co-resident BASIC DATA (Basic personal data) Longitudinal Reference period: current Unit: all current household members (of any age) Mode of collection: household respondent or register Values 1 sample person 2 co-resident Sample persons: Means all or a subset of the members of the households in the initial sample who are over a certain age. Initial sample: Refers to the sample of households or persons at the time it is selected for inclusion in EU- SILC. Age limit used to define sample persons: In case of a four-year panel, this age limit shall not be higher than 14 years. In countries with a four-year panel using a sample of addresses or of households, all household members aged 14 and over in the initial sample shall be sample persons. In countries with a four-year panel using a sample of persons, this shall involve the selection of at least one such person per household.
