In 2014, for the first time, the children themselves answered the “Pupils” questionnaire. In addition, the data from the Families in Germany (FiD) study was integrated into the SOEP in 2014 as well. There are six different “Mother & Child” and “Parent” questionnaires and two “Pupils” questionnaires (see Table 1). Two additional questionnaires (biage02 and bioage10b) were only surveyed in FiD but are integrated into the bioagel data set, too. Table 1: Overview of bioage data, corresponding age group, and respondents Bioage Classification by Age Respondents First Wave Bioage01 0-1 years old Mothers only 2003 Bioage02 (FiD only) 1-2years old Mothers only 2010 Bioage03 2-3 years old Mothers only 2005 Bioage06 5-6 years old Mothers only 2008 Bioage08a 7-8 years old Parent 1 2010 Bioage08b 7-8 years old Parent 2 2010 Bioage10 9-10 years old Parent 1 (SOEP & FiD) 2012 / 2010 (FiD) Bioage10b (FiD only) 9-10 years old Parent 2 (FiD only) 2010 Bioage12 11-12 years old Children 2014 Bioage14 13-14 years old Children 2016 The “Mother & Child”, “Parent” and “Pupils” questionnaires aim to follow and observe future generations of the SOEP and collect all information in age-specific files, even though the data come from different survey years. As we try to make this process as comprehensive and gapfree as possible, we begin following and documenting the development of children in SOEP households from birth onwards. Since many questions overlap, all bioage data files are covered in this chapter, rather than dedicating a separate chapter of this document to each bioage data 1 This documentation is based on earlier versions of documentation materials on bioage data sets and has benefited from previous work by Sebastian Frischholz, Anne Fromm, Stefanie Lenuweit, Katharina Mahne, Christian Schmitt, and Jürgen Schupp. file. By doing so, we are able to provide you with an overview of all variables covered in the bioage data files. Starting with the v31 data distribution, all available data is now provided in one data set: bioagel. The separate bioage data files are no longer part of the data distribution. 2 Respondents in the ‘Bioagel’ Data Set The values of the BIOAGE variable in the bioagel data file reflects the age of the children when the respective questionnaire was taken by their parents (e.g., bioage = 6 covers children who turned six that survey year, producing a range in ages between 5 years and 1 month and 6 years and 11 months, depending on the birth month and interview month). For information on the questionnaires used with each age group, please see Table 1. Except for bioage08b, bioage12, and bioage14 (and – FiD only – bioage10b), it is usually the mother who completes the questionnaire. In the exceptional case that a mother cannot complete the questionnaire, the father does. The respondents’ personal ID numbers (regardless if fathers, mothers or other care takers) are provided in the variable PERSNRESP in the bioagel data set. Note that while the parents are the actual respondents (except for bioage12 & bioage14, covering the “Pupils” questionnaire), the data are organized under the child’s unchanging personal ID number (PERSNR). Bioage01: “Mother and Child” Questionnaire, Children Aged 0-1 years The questionnaire is given to all women who gave birth to a child in the current or previous survey year, and to all women whose non-biological child was born in the same period. The questionnaire contains information on pregnancy, childbirth, childcare, and child health. In the exceptional case that a mother is unable to complete the questionnaire, the father responds. Bioage02: “Your child between the ages of one and two”, Children Aged 1-2 years (FiD only) The questionnaire is given to all mothers whose child turns two in the current survey year. In the exceptional case that a mother cannot complete the questionnaire, the father responds. Bioage03: “Your child between the ages of two and three”, Children Aged 23 years The questionnaire is given to all mothers whose child turns three in the current survey year. In the exceptional case that a mother cannot complete the questionnaire, the father responds. Bioage06: “Your child between the ages of five and six”, Children Aged 5-6 years The questionnaire is given to all mothers whose child turns six in the current survey year. In the exceptional case that a mother cannot complete the questionnaire, the father responds. Bioage08a and Bioage08b: “Parent” Questionnaire, children aged 7-8 years The questionnaire is given to both mothers and fathers of children turning eight in the current survey year. Data of parent 1, which is usually the mother, can be found in bioage08a. Data of parent 2, which is usually the father, can be found in bioage08b. Bioage10: “Your child between the ages of nine and ten”, Children Aged 910 years (only FiD: Bioage10b) The questionnaire is given to all mothers (FiD: and fathers) whose child turns ten in the current survey year. In the exceptional case that a mother cannot complete the questionnaire, the father responds. Data of parent 1, which is usually the mother, can be found in bioage10a. Data of parent 2 (FiD only), which is usually the father, can be found in bioage10b. Bioage12: “Pupils between the ages of eleven and twelve”, Children Aged 11-12 years The questionnaire is given to all children themselves who turn(ed) twelve in the survey year. Bioage14: “Pupils between the ages of thirteen and fourteen”, Children Aged 13-14 years The questionnaire is given to all children themselves who turn(ed) fourteen in the survey year. Number of Children and Twins in the Bioage Data Sets The data set has grown over the years and now contains data on 13,363 children. At the moment (2016), there are 66 children for whom information has been provided through all of the “Mother & Child”, “Parent”, and “Pupils” questionnaires (bioage01, bioage03, bioage06, bioage08a/b, bioage10, bioage12, and bioage14). Data are available for 170 children from seven questionnaires, 339 children from six questionnaires, 1,044 children from five questionnaires, 2,149 children from four questionnaires, for 2,031 from three questionnaires, and for 3,269 children from two questionnaires. For 4,295 children, data are available from one questionnaire. An overview of the number of children in each data set is given in Table 3.

Note that there might be more children in the household than indicated here: these children are not in the age range of the “Mother & Child”, “Parent”, and “Pupils” questionnaires and therefore not covered by the bioagel data set.

Bioage01 contains 103 pairs, bioage02 57 pairs, bioage03 109 pairs, bioage06 80 pairs, bioage08a 85 pairs, bioage08b 53 pairs, bioage10 72 pairs, bioage10b 24 pairs, bioage12 29 pairs of twins, and bioage14 8 pairs. 3 Topics and Variables The bioage data contain information regarding  Pregnancy and childbirth  Child health  Childcare situation  Changes in living circumstances since birth of child  Child’s abilities  Parenting experiences  Expectations about the child’s success in school  Educational goals and aspirations of the parents  Educational behavior of the parents  Self-conception of the role of parents  Self-report: independence and social experience  Self-report: importance of social contacts  Self-report of savings  Self-report: interest in politics The rules used to generate the variables from the questionnaires are consistent over the various bioage questionnaires. In the new integrated bioage long data set, the data is presented in “long” format, i.e. this dataset contains information from bioage01, bioage03, bioage06, bioage08a and bioage08b, bioage10, bioage12 as well as bioage14. In addition, all variables from the FiDStudy are included as well: if there was a corresponding SOEP Variable, the data was combined into the SOEP variable; if there was no corresponding SOEP Variable or if the data was coded differently, the information is provided in separate variables with the suffix _fid. A few variables are generated by combining the information from two or more variables. The present documentation provides detailed information on variables generated using information from other files. An overview of the specific variables and the rules by which they were generated is given in section 10.4 “Generated Variables”.
