Family blending
About this topic
Family blending classifies couple families with children according to whether the children are shared by both partners, from a previous relationship, or a mix of both. It applies only to couple families with children, not to all family types or all households.
This topic can help show patterns of repartnering and family complexity within an area. It should be interpreted with household type and households with children, because it is a specialised family-structure measure rather than a summary of all families.
Interpretation notes
- This derived family view applies only to couple families with children, not all families or all households.
- It classifies whether children are shared, step, or blended within the couple family, so it should not be compared directly with headline household totals.
