Last month the Department of Treasury and Finance released its latest population projections for Tasmania. The projections cover the period 2013-2062 and the medium series sees our population grow by around 65,000 people in the next 50 years. The low and high projections--which do not necessarily provide either higher or lower limits of population for the decades ahead--see Tasmania's population decline by 68,000 and grow by roughly 240,000 people, respectively.
Notably, the medium series projects that in 2062 Tasmanian men will outnumber Tasmanian women by around 6,600--the opposite of our current sex distribution. Mother nature has always ensured that more boys are born than girls (evolutionary demographers suggest this is due to men's increased health complications and risk taking behaviour), and it is likely this pattern will continue. What is unlikely however, is whether in the future Tasmania will 'rain' men.
Last year, men outnumbered women in all age groups in Tasmania except those between 35-59 (and those in the very old age groups due to women's increased life expectancy over men). Notably, the majority of this difference can be explained in terms of net migration losses to the mainland. In 2012, the largest group to leave the state were men aged between 35-59 years old--presumably for better employment/wage opportunities given Tasmania's current economic climate.
Unless effective policies can be designed and implemented in order to retain Tasmania's working age population, it is unlikely that Tasmania will 'rain' men in the foreseeable future.
