LSAC
Growing Up in Australia: The Longitudinal Study of Australian Children. A nationally representative longitudinal study of child development that commenced in 2004. Data is collected from study children, and their parents, carers and teachers, and through linkage with other national datasets.
Parent 1
The child's primary parent, defined as the child's primary caregiver, or the parent who knows the child best. In the majority of cases, this is the child's biological mother, but can also be the father or another guardian.
Parent 2
The child's second parent, usually the partner of the primary parent. In most cases, this is the child's biological father, but can also be the mother, another partner of the primary parent, or another guardian.
Study child (or child)
The sampling unit for LSAC is the study child, so "child" refers to the child selected for inclusion in the study. Data collected and reported relate to this child.
