STATISTICAL LINKAGE KEY
Technical name: Record - linkage key, code 581 XXXXXDDMMYYYYN
METeOR identifier: 349895
METeOR link: <http://meteor.aihw.gov.au/content/index.phtml/itemId/349895>
METeOR definition: A key that enables two or more records belonging to the same individual to be brought together. It is represented by a code consisting of the second, third and fifth characters of a person's family name, the second and third letters of the persons' given name, the day, month and year when the person was born and the sex of the person, concatenated in that order.
Scope
Inclusions: For all children enrolled in a preschool program, include in the following order:
- the second, third and fifth letters of the child's family name.
- the second and third letters of the child's given name.
- the day, month and year of birth of the child, concatenated in that order to form the child's date of birth.
Exclusions:
- Children not enrolled in a preschool program.
- Exclude the following components:
- the first, fourth, sixth, and any subsequent letters of the child's family name.
- the first, fourth, and subsequent characters of the child's given name.
- hyphens, apostrophes or spaces which may form part of a child's family name or given name.
Underlying Concepts
Concept: Statistical Linkage Key 581.
Nominal definition: Consistent with METeOR definition.
Operational definition: Consistent with METeOR definition.
Supporting data elements: The following data elements are used to develop the statistical linkage key:
Conceptual issues:
- The statistical linkage key enables counting the number of children and the preschool programs they received, without counting the same child more than once. The intention of this data element is to create a unique key for each child; however in practice it is possible for a derived SLK to exactly match the derived SLK of another child or children. In this small percentage of cases, additional available data can be used to confirm the validity of a match. For more information on matching SLKs and how the ABS recommends they are flagged, see Chapter 1, Collection Specifications.
