| The basis of the family relations data within Lifelines consists of information from the municipal registries (Basisregistratie Personen (BRP)). Based on this information, researchers from the [[ugli|UGLI-consortium]] have optimized the family relations using recoded surname data (for privacy purposes) and data from questionnaires ([[family_composition|Family composition]]). The process of this optimization has been documented and can be found here: {{ :lifelines_familyreconstruction.pdf | Family relations reconstruction}}. | The basis of the family relations data within Lifelines consists of information from the municipal registries (Basisregistratie Personen (BRP)).
