Abstract:
A consistent correction procedure is used to determine improved, consistent estimates by sex of census age distributions, intercensal births, and intercensal deaths and net immigration by age for the Aboriginal populations of the Northern Territory, South Australia and Western Australia during the period 1986-91. Undercount estimates for the censuses, registered births and registered deaths, and life tables derived from the results show the Aboriginal populations to have lower coverage of censuses and of vital events and much higher death risks than the total Australian population. Interregional net migration estimates show that component of change may no longer be ignored.
