MISSING AND/OR INCONSISTENT INFORMATION
In these cases, the true record pair was present in the pool of possible links but it was not identified because there was a high level of inconsistency between information on the death registration and Census record or key linking fields were missing. As a special case, while a resident in a nursing home or hospital may have been included on a Census summary form for that institution, there would be insufficient information on such a form to establish a link to a death registration.
Address information was crucial in narrowing the search for and differentiating between true and false links. The fact that a person could relocate in the time period between Census enumeration and death increased the difficulty of linking the equivalent records to each other, and added uncertainty to clerical review.
Address information from the pool of linked records provides some insight into why the Aboriginal and Torres Strait Islander deaths may have been more difficult to link than non-Indigenous deaths. Linked Aboriginal and Torres Strait Islander death registrations had a higher rate of disagreement for geographic areas such as Mesh Block (30%) and SA2 (17%) than linked non-Indigenous death registrations (21% and 11% respectively).
