SUMMARY RESULTS OF THE CDE STUDY

The number of Census and death registration records eligible for linking and the percentage of death records linked are presented in Table 3.1. The linking process used 177,380 death records and 22,485,854 Census records. These Census counts are different from the estimated resident population, as discussed in Chapter 2: Population estimates of Aboriginal and Torres Strait Islander Australians.

Of the 177,380 death records, 159,657 (90.0%) records were linked to one of 22,485,854 eligible Census records. Of the 3,246 Aboriginal and Torres Strait Islander death records, 2,315 (71.3%) were linked.

(a) Excludes residents temporarily overseas on Census night, imputed records and Census net undercount adjustment.
(b) Deaths which occurred between 09 Aug 2016 and 28 Sep 2017.
(c) According to Indigenous status reported on death registration form.

The number and percentage of death records linked to Census records by selected characteristics of deceased persons are presented in Table 3.2. A slightly higher linkage was achieved for females (91.4%) compared with males (88.6%). The linkage rate varied considerably by age, being lowest for 0-14 year old deceased persons (63.4%). This may be due to the comparatively high Census undercount rate in this age group. The linkage rate was highest for 75 years and older deceased persons (92.9%).

The linkage success varied by state of usual residence as reported on the death registration form. Rates were highest for South Australia (91.5%) and lowest for the Northern Territory (72.9%). All other states and territories had linkage rates between 88.8% and 90.9%. The low linkage rate for the Northern Territory reflects comparatively low linkage rates for both the Aboriginal and Torres Strait Islander and non-Indigenous populations. The linkage rate was similar for married and widowed persons (92.2 and 92.6% respectively). The linkage rate was lower for deaths which occurred within six months of the Census (88.8%) than those which occurred beyond six months after the Census (91.0%).

The linkage success also varied by Indigenous status recorded on the death registration form. People of non-Indigenous origin on the death registration form had a considerably higher linkage success (90.4%) compared with people of Aboriginal and Torres Strait Islander origin (71.3%). A more strict approach to implementing the 2016 linkage clerical review resulted in a lower, but more accurate linkage rate then in 2010-2012.
