SOEP-Core soep.v33.1

1 Deletion of incorrectly conducted interviews in the IAB-BAMF-SOEP Survey of Refugees

In the process of preparations for the next wave of the IAB-BAMF-SOEP Survey of Refugees, the survey institute determined that an interviewer had not conducted interviews correctly, affecting six percent of the household interviews in the sample. These households were removed from the dataset, but are available upon request for survey methodological analysis at a guest work station at the SOEP Research Data Center. In addition to deleting these lines of all affected datasets, we also made the following modifications:

• Due to the deletion of household and individual interviews, the weights had to be updated (dataset HHRF and PHRF) to take the slightly reduced number of cases in the 2016 survey year into account.
• The new weights were updated or included in the dataset BGPEQUIV.
• Imputation of monthly household net income (I[1-5]HINC16) was redone for this sample in BGHGEN and in the dataset MIHINC.
  
  

2 Update INTID in BG files

Datasets from the current BG wave contained errors in the assignment of interviewer IDs. These were corrected.

3 Corrected number of entries in `$$KIND' (2014-2016)

Inconsistencies between key variables on population assignment in the PPFAD and $$KIND datasets were corrected. There was an error of one year in the definition of the target population in the $$KIND datasets from 2014 to 2016. In some cases, this led to a lack of information on the year of birth in files on children:

• bekgjahr: 1998 for all samples
• bfkgjahr: 1999 for all samples
• bgkgjahr: 1999 only for samples M3 and M4 in 2016

These corrections also affect the number of cases in the file KIDLONG, which was corrected correspondingly.

3.1 Change in the $$NETTO codes in 96 cases (children) in the years 2014-2016

In the process of data checks, the $$NETTO codes in PPFAS were also compared and corrected. In survey years 2014 to 2016, some children had been incorrectly assigned the code 20 instead of 30 on the variable $$NETTO in the PPFAD dataset. This error has been corrected in v33.1 with the correction of the variable $$NETTO. The update also made it necessary to correct person weights in the affected survey years (dataset PHRF), because the determination of which individuals in interviewed households should be assigned a valid weight is based on the variable $$NETTO. The updated weight is also contained in v33.1.

4 Update BIOPAREN

In BIOAPREN, a number of missing values in the flag variables for parental (professional) education and the years of death of the parents were updated and filled in.

5 Update MIGSPELL

The algorithm for imputation of missing dates in the spells were optimized. As a result, in v33.1, the imputed variables and the variables imputed from these were changed, specifically all variables with the suffixes _imp and the variable staytime. The changes affected a total of 349 of 15,640 spells.

6 Update AUSB16 in BGPGEN

The variable AUSB16 (“profession requires vocational training”) from BGPGEN were updated. The correction substantially decreased the number of missings [-1].

1. Dataset $PGEN: Variable casmin$$

A missing parenthesis in programming led to individuals in CASMIN category 6 (“(2c_gen) general maturity certificate”) being mistakenly placed in CASMIN category 7 ("(2c_voc) vocational maturity certificate").

For wave BG, this means that of the 4,553 observations in category 7, 1,976 actually belong in category 6 and 2,577 in category 7.

This can be corrected with the existing variable in the $PGEN data. For wave BG, it can be done as follows:

2. Dataset [BE-BG]PGEN: Variable [be-bg]pbilla ("Vocational Degree Outside Germany") 

The variable $$pbilla (foreign degrees – vocational education) in SOEP v33 was expanded retrospectively to include information on whether the degree had been completed. This revision failed, however, to take into account some of the information covered in certain modules. A correction can be made with the existing variables in the $PGEN data, as shown here: Statement | TXT, 2.72 KB

3. Dataset BIOAGEL: Variable bioage

In the dataset BIOAGEL,the data type was not adjusted for the variable bioage. The variable shows which questionnaire the row of data was taken from. Since the variable bioage has included values > 99 since v33, this led to values > 99 being cut off in Stata. The cut-off values are:

4. Dataset CIRDEF: Variable rgroup

The variable rgroup divides the SOEP sample into 20 equally sized groups. It is used to select the 50% sample. Since the new samples M3 and M4 were incorrectly assigned, there are no cases from these samples in the teaching version of the SOEP data.
