The share of single parents and reconstituted families has substantially increased during the last century. These households tend to face higher risk of poverty and deprivation. Within these households, the particular ‘status’ of children in shared custody requires methodological development. In most surveys, these children are fully recorded in the surveyed household, independently of the amount of time they spend in this household. Additional data on the time spent by children with their respective parents were collected for the first time at the EU level in the 2021 EU-SILC ad-hoc module and could be used to refine the existing analyses. The project aims at investigating the custody arrangements of children and at this information in a broader analysis of risks factors of child deprivation in Belgium, which will also include parents’ joblessness, education, country of origin, (re-)equivalised income, housing tenure status and regions.
