Donor assumption forecast dataset explained Place Forecast Feature

Referenced by 2 other explainers

The donor assumption forecast dataset is an axiomatic dataset. It is a council dataset that banks demographic behaviour captured from a donor area: fertility, mortality and migration rates by age and sex, plus the age and sex mix of in-migrants.

Each behaviour is held at its own latest estimated year, which is why the columns on the detail page carry different years.

A recipient small area names one of these donations on a Donor row in the housing and dwelling assumptions. An area does this when it holds too few people per age and sex cell for its own rates to be stable. The donation replaces the area's rates from the first projected year. Donated out-migration rates start later, in the first year no published estimated resident population covers. Until then the area's own out-migration rates split its migration in the years the ABS has already estimated.
