In 2014, for the first time, the children themselves answered the “Pre-teen” questionnaire. The “Early Youth” questionnaire was introduced in 2016. 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 questionnaires that are answered by the children themselves: the “Pre-teen” and the “Early Youth” questionnaires (see Table 1). Two additional questionnaires (biage02 and bioage10b) were only surveyed in FiD but are integrated into the bioagel data set, too.

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 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 v34 data distribution, all available data is now provided in two data sets: Bioagel and Biopupil. The separate bioage data files are no longer part of the data distribution. 2 Respondents in the ‘Bioagel’ and ‘Biopupil’ Data Sets The values of the BIOAGE variable in the bioagel and biopupil data files reflects the age of the children when the respective questionnaire was taken by their parents (bioage01 – bioage 10) or answered by themselves (bioage12 and bioage14). For example, 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 “Pre-teen” and “Early Youth” 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. SOEP Survey Papers 878 2 v35 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 and Biopupil Data Sets The data set has grown over the years and now contains data on 18,138 children. At the moment (2018), there are 174 children for whom information has been provided through all of the “Mother & Child”, “Parent”, “Pre-teen”, and “Early Youth” questionnaires (bioage01, bioage03, bioage06, bioage08a/b, bioage10, bioage12, and bioage14). Data are available for SOEP Survey Papers 878 3 v35 382 children from seven questionnaires, 1,717 children from six questionnaires, 3,306 children from five questionnaires, 4,876 children from four questionnaires, for 6,708 from three questionnaires, and for 10,278 children from two questionnaires. For 18,138 children, data are available from one questionnaire.

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”, “Pre-teen”, and “Early Youth” questionnaires and therefore not covered by the bioagel and the biopupil data set.

In the integrated bioage and biopupil data set, the data is presented in “long” format, i.e. the bioagel dataset contains information from bioage01, bioage03, bioage06, bioage08a and bioage08b, as well as bioage10 and the biopupil dataset contains information from 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.
