This report is the result of a unique project: the Belgian Gender and Income Analysis (BGIA). Its objective was to produce a gender-aware analysis of the existing income data and the development of gender and income indicators. This was necessary for several reasons. The first and probably most obvious reason is gender mainstreaming: adequate policy preparation demands that the situations of men and women are taken into account in every domain. This is most certainly the case in the field of the prevention of and the fight against poverty, where income indicators have been well-established for a long time. A second important reason is to further explore the possibilities of existing income data. The collection and processing of high quality statistics gains value when maximum use is made of these data. The third reason is a scientific one. The field of tension between the analysis of data on a household level or an individual level is a recurrent theme in science. Both approaches have their merit. In poverty research the analysis on an individual level has hitherto been lacking. Among other things within the context of the debate on the individualization of social security rights it is important to be able to compare both analyses.
