Fertility, migration, and the ageing of the population--an analysis of the official projections.

Abstract

"As we move through the demographic transition, an older age structure is inevitable but future possible scenarios vary.... The paper analyses nine different population projections produced by the ABS [Australian Bureau of Statistics], four in 1996 and five in 1998. The highest projection...adds an extra ten million people by the year 2051 while the lowest...adds none."
