Some of these questions are consistent with content of the independent Youth Questionnaire (for detailed information on the Youth Questionnaire, see chapter 13). The expanded questionnaire asks respondents of all ages to describe aspects of their life at the age of 15, including their relationship with parents, grades in school, the federal state where they last attained educational qualifications, detailed information on vocational qualifications, as well as intentions to complete further education or vocational training. Questions concerning military and alternative services are also included in this data set. As these questions are a part of the standard Biography Questionnaire, they are only asked once. Some of these questions can, however, be followed up by the regular data collected in the Individual Questionnaire. For example, if someone was too young to have completed his educational career when the Biography Questionnaire was conducted, the user can look at the yearly data in later years or at the BIOEDU dataset to track the complete educational career of a sample member. 1 Replaces earlier versions by Henning Lohmann and Sven Witzke; Jürgen Schupp and Michael Frühling; Bettina Isengard and Thorsten Schneider and Mila Staneva. survey year frequency 2000 246 2001 8,819 2002 552 2003 2,328 2004 450 2005 299 2006 223 2007 2,232 2008 336 2009 196 2010 2,038 2011 14,797 2012 2,855 2013 5,370 2014 552 2015 2,129 2016 4,892 2017 7,072 Total 55,368 sample frequency A: Germans (west) 977 B: Foreigners (west) 270 C: Germans (east) 655 D: Immigrants 19841993 136 E: Supplement 1998 263 F: Innovation 2000 9.911 G: High-Income 2002 2.279 H: Supplement 2006 2.217 I: Incentivation 2009 1,870 J: Supplement 2011 5,504 K: Supplement 2012 2,620 L: Family Samples 11/12 10,131 M: Migrants 14,835 N: Supplement 2017 3,718 Status: up to wave BH (2017) SOEP Survey Papers 749 1 SOEP v34 The data set BIOSOC contains information on all sample members that entered the sample via refreshments or household formation since 2000. These are 55,368 persons. Biographical data collected before 2000 are stored in the dataset BIOL. The dataset BIOL contains additional 26,259 persons from 1984 to 1999. In 2014, Data from the SOEP-related FID-study from the years 2010 to 2014 has been integrated in the SOEP (Sample L). Therefore, the number of cases in BIOSOC has increased with SOEP Version 31 retrospectively for the years 2011 to 2013, compared with previous versions. You might want to use the psample-variable as filter, if you want to exclude these cases and reproduce your old sample. 1 Structure of the Data Set BIOSOC Respondents are given the Biography Questionnaire only once in a lifetime. Some of the information stored in the new data set BIOSOC is invariant (such as the relationship to parents at the age of 15) or is not surveyed to such an extent in the regular questionnaire (such as last school grades). Consequently there is only one record for each person and updates are not intended for this data set. The variable SYEAR makes it possible to quickly identify the year of the survey. Using the variable BSGEBJAH, which contains the year of birth, the user can determine the respondent’s age. If the respondent is of a certain age, one can assume that some of the variables are constant. This applies to variables such as last school grades or military service. In Table 1 (at the end of the chapter) all variables of the data set BIOSOC are listed. The first column contains the name of the variable, the second a brief specification of its content. The third column contains the number of the question as it appears in the Biography Questionnaire of wave Q (2000). The columns four to eight contain the question numbers in waves R to BG (2001-2016). The next four columns list question numbers of the Migration Questionnaire. The penultimate column contains the number of question for the refugee samples. In the last column the corresponding variable in the BIOAGE17 data set is given, if available. A minus sign means that the variable is not available in a given years and a question number in parenthesis indicates limited comparability. 2 Special Features of Some Questions and Variables - The interviewees were asked if they did sports in their youth. If a respondents answer was positive, (s)he were asked to include the sport they participated in most frequently. This information was re-coded to a numeric variable and categorised. Some categories could easily be coded, such as soccer, whereas for others this was not SOEP Survey Papers 749 2 SOEP v34 possible. For users interested in specific research questions on sports in youth, the original plain text answers can be provided upon request. - Respondents were asked: “When was the last year you attended school?” (Question 46). If they were still attending school, they had the opportunity to report that they were students. Unfortunately in the years 2001 to 2003, individuals who reported being students or who did not provide any answer to this question skipped over numerous questions due to the questionnaire design. Consequently, for these individuals there is no information on the number of foreign classmates2, on the school degree aspired to, or planned vocational qualifications. Their record also lacks information on past vocational qualifications. However, this should prove less problematic since most of the students were enrolled in regular school programs throughout the entire time. - In 2011, the Biography Questionnaire was integrated in the Individual Questionnaire for the samples J and K. For these samples a new variable was introduced – BSDAUER3 – which shows the interview duration with the integrated questionnaire version. All other samples are coded with “-6” on this variable. - In 2012, sample M containing only respondents with migration background was added in SOEP (SOEP Survey Paper 216). This sample was surveyed with a modified version of the Biography Questionnaire which focuses on the immigration history and therefore misses some of the standard questions from the original Biography Questionnaire (SOEP Survey Paper 218). The last column in Table 1 gives an overview of the variables in BIOSOC available for the migration sample. A minus signs means that the variable is not available for sample M (in the Data, we used the missing code “-5” in such cases). A question number in parenthesis indicates that the question in the Migration Questionnaire is comparable, but not identical to the question in the original Biography Questionnaire. - In 2016 a new refugee sample was integrated into BIOSOC. The questions about vocational training and university degree acquired abroad were asked in loops: Questions about the application and result of the recognition process were asked for every acquired degree. Therefore, the variables BSBAAEND and BSBAAZEU are the condensed variables. - Besides the simplification of educational information for the sample M, we harmonized also different versions of questions. Especially the whole questions about occupational training and university acquired abroad have different answer categories in the questionnaire for samples A – L, M1/M2 and M3/M4/M5. 2 Most persons with no valid information on foreign classmates are not students but individuals who finished school abroad. This is because the question only targets those in German schools. SOEP Survey Papers 749 3 SOEP v34 - Concretely, the variable BSBAAZEU was harmonized. The core samples were asked if they received a certificate for their degree with the option to answer yes or no. The samples M1 and M2 were only asked if they completed their occupational training / university degree successfully. M3, M4 and M5 had three answer categories (did not complete the training, ended without qualification and ended with qualification). To unify all the answers we used the core questionnaire as a starting point. The category “yes” of the variable BSBAAZEU are the category “completed successfully” for M1/M2 and the category “ended with qualification” for M3/M4/M5. For the answer “no” of BSBAAAZEU we had to recode the categories “ended without qualification” and “did not complete the training” for M3/M4/M5 into one category. - The variables BSBAAABA, BSBAAARA, BSBAAAMB, BSBAAAMJ and BSBAAAGA were not generated for the Migration samples. The above mentioned variables are repeated in the Individual Questionnaire. These variables are stored in the data set $P. If you are interested in the status of recognition, please use the current data set $P.
