Generations and Gender Survey Belgium Wave 1

Alternate Title

GGS Belgium Wave 1


The Generations and Gender Survey (GGS) provides micro-level data with the aim of significantly improving the knowledge base for social science and policymaking in Europe and developed countries elsewhere. In Europe 2020, the European Union develops a strategy "to help us come out stronger from the crisis and turn the EU into a smart, sustainable and inclusive economy delivering high levels of employment, productivity and social cohesion". The economic crisis affects not only day-to-day decisions, but also fundamental choices at all stages of people's lives: marriage and childbearing, the combination of employment and caring responsibilities for the young and the old, retirement, housing, and ageing well. The GGS has been developed to provide scientists with high-quality data to contribute scientifically grounded answers to these key policy questions. Survey content focuses on intergenerational and gender relations between people, expressed in care arrangements and the organization of paid and unpaid work. Key feature of the survey are:

  • Cross-national comparability. In each country data is collected on the basis of a common international questionnaire and guidelines about the methodology. Data processing includes central harmonization of national datasets.
  • A broad age range. It includes respondents between the ages of 18 and 80.
  • A longitudinal design. It has a panel design, collecting information on the same persons at three-year intervals.
  • A large sample size. It has an average of 9,000 respondents per country at Wave 1.
  • A theory-driven and multidisciplinary questionnaire. It provides data for policy relevant research by demographers, economists, sociologists, social policy researchers, social psychologists and epidemiologists. The questionnaire is inspired by the theory of planned behavior.
  • Possibility to combine the survey data with macro data provided by the GGP Contextual Database. This combination enables analyses of individuals and families in their cultural, economic, political, social and policy contexts.
The Belgian questionnaire includes some questions that are not present in the international questionnaire. These questions regard disability of household members in daily activities, fertility treatments and any eventual problems during previous pregnancies.

Data Collection

Data Collection Date
Mode of Data Collection

Method: Face-to-Face (personal interview). Technique: Computer-Assisted (CAPI).

Collection Situation
  1. Interviewers
  • Interviewer training: Interviewers were informed about general basic rules of interviewing. During the training, the following topics were dealt with: contacting procedure, confidentiality issues, before interview protocols (including techniques to persuade contacts to participate to the survey), interviewing method and best practices. Interviewers were also provided with relevant documentation concerning the survey.
  • Control of performance: To monitor the work of interviewers during the fieldwork, a follow-up was organized on a weekly basis, through the so-called "group monitor". In case of doubt about the work and the good intentions of the interviewer, he/she could be asked to give his/her group to another interviewer.
  1. Contact protocols 2.1 Advance letter: No. Interviewers could announce their visit visit by a letter. But this was not compulsory. 2.2 Cold contacts: Face-to-Face 2.3 Scheduling / scattering: Yes. To get the highest response rate, contacts attempts were scattered over different days of the week and different parts of the day. 2.4 Contact history: Yes. For each contact attempt, the interviewer had to report the date, the time and the outcome in a contact form. 2.5 Min number of contacts: 3 (at least one time at the individual's home, at least one time in the evening and one in the weekend). 2.6 Max number of contacts: 10.

  2. Questionnaire localization

  • Pre-test: a pilot study was carried out in June 2007, on a random sample of N=1000. However, only 107 individuals accepted to participate and, of them, only 72 were actually interviewed. As a result, the pilot was really biased in terms of age and education profiles. This experience suggested asking respondent with an informed consent form.
  • Lenght of interviews: median duration equal to 69 minutes. The optional modules on "Housing" and "Nationality & Ethnicity" were only partially implemented in Belgium. The “Housing” module overlaps with the Belgian censuses that are carried out since 2001. In order to make the GGS international questionnaire compliant with the Belgian National Law, some questions have been modified/omitted. Some response categories have been modified. Once translated in French, Dutch and German, the questionnaire was not re-translated back in English.


Time Method


Sampling Procedure
  1. Sampling frame: The total Belgian population was equal to 10,666,866 individuals (source: STATBEL), as of 1 January 2008 when the sample was drawn; the survey population was equal to 7,828,470 persons at that moment. This is 73% of the total Belgian population at that moment.

  2. Sampling method: On the one hand, a random sample, i.e. a stratified two-stage sample using the National Register as basis; 17,836 people in total were selected this way. On the other hand, corrections were implemented through weighting factors, after analysis of the non-response (at interview as well as at item level).
