Box 15: The Working Age Population
The working age population is typically taken to be the population aged 15-64 years, even though relatively few people at the lower and upper bounds of this age group are - these days - actually in the labour force. The graph shows the growth and levelling off of this population in Tasmania over the past 37 years, and its projected peak around 2011 and thereafter slow decline. Of import to this scenario is that it is heavily dependent on the migration assumption of a sustained annual net gain of around 940 persons (and a birth rate of around 2.08 which will deliver new labour market entrants some 17-18 years later). Underlying the migration assumption is that the majority of the gain will be of youthful international students. Accordingly, users of these data should be aware that such persons may not be available to the labour market, in which case the projected decline may be greater than indicated.
